It had but just gone midnight when the car slowed down before the house in Clarges Street. Here in company with his faithful henchman, Dollops, and attended upon by an elderly housekeeper and a deaf-and-dumb maid of all work, there dwelt under the name and guise of “Captain Horatio Burbage,” a superannuated seaman that strange and original genius who chose to call himself “Hamilton Cleek,” but who was known to the police of two continents by the sobriquet of “The Man of the Forty Faces.”

In the merest fraction of a minute Narkom was out of the limousine, had crossed the narrow pavement, mounted the three shallow steps, and was standing in the shadow of a pillared porch, punching a signal on the button of an electric bell. In all he could not have been kept waiting more than a minute, but it seemed forty times that length when he at last heard a bolt slip, and saw, in the gap of the open door, the figure of a slim, red-headed youth arrayed in a bed quilt, a suit of pink flannelette pajamas, and a pair of white canvas tennis shoes.

“Come in, sir, come in quick!” this young man whispered, in the broadest of Cockney accents, as he opened the door just wide enough for Narkom to sidle into the semi-dark passage.

“Where’s your master, Dollops?” put in the superintendent. “Speak up! Is he in? I’ve got to see him at once!”

The voice which answered came, not from Dollops, but from the dark top of the dim staircase.

“Come up, Mr. Narkom,” it said. “I thought that young beggar had gone to bed ages ago and was just coming down myself to let you in. Come along up. You know the way.”

Narkom acted upon the invitation so promptly that he was up the stairs and in the cozy, curtained, and lamp-lit room which Cleek called his den almost as quickly as his host himself. In fact, Cleek had scarcely time to sweep into the drawer of his writing table a little pile of something which looked like a collection of odds and ends of jewellery, bits of faded ribbon, and time-stained letters, and turn the key upon them, before the police official was at the door.

“Hullo!” said Cleek in a tone of surprise and deep interest as the superintendent came fairly lurching into the room. “What’s in the wind, Mr. Narkom? You look fairly bowled. Whisky and soda there at your elbow help yourself. I presume it is a case nothing else would bring you here at this time and in such a state. What kind is it? And for whom? Some friend of yours or for the Yard?”

“For both, I’m afraid,” replied Narkom, pouring out a stiff peg of whisky and nervously gulping it down between words. “God knows I hope it may be only for the Yard, but considering what I know Get your hat and coat. Come with me at once, Cleek. It’s a murder a mystery after your own heart. Lennard’s below with the limousine. Come quickly, do, there’s a dear chap. I’ll tell you all about it on the way. The thing’s only just been done within the hour out Wimbledon way.”

“I might have guessed that, Mr. Narkom, considering that you were to mingle duty with pleasure and spend the evening at Wimbledon with your old friend, Sir Philip Clavering,” replied Cleek, rising at once. “Certainly I will go with you. Did you ever know the time when I wouldn’t do all that I could to help the best friend I ever had yourself? And if it is, as you hint, likely to be in the interest of the friend of my friend ”

“I’m not so sure of that, Cleek. God knows I hope it’s a mistaken idea of mine; but when you have heard, when you have seen, how abominably things point to that dear boy of Clavering’s and to the girl that dead fellow was conspiring with her father to take away from him ”

“Oho!” interjected Cleek, with a strong rising inflection. “So there is that element in the case, eh? love and a woman in distress! Give me a minute to throw a few things together and I am with you, my friend.”

“Thanks, old chap, I knew I could rely upon you! But don’t stop to bother about a disguise, Cleek, it’s too dark for anybody to see that it isn’t ‘the Captain’ that’s going out; and besides, there’s everything of that sort in the limousine, you know. The street is as dark as a pocket, and there’s nobody likely to be on the watch at this hour.”

The curious one-sided smile so characteristic of the man looped up the corner of Cleek’s mouth; his features seemed to writhe, a strange, indefinable change to come over them as he put into operation his peculiar birth gift; and an instant later, but that he had not stirred one step and his clothing was still the same, one might have thought that a totally different man was in the room.

“Will it matter who watches?” he said, with just a suspicion of vanity over the achievement. “It will be let us see yes, a French gentleman whom we shall call ‘Monsieur Georges de Lesparre’ to-night, Mr. Narkom. A French gentleman with a penchant for investigating criminal affairs, and who comes to you with the strong recommendation of the Parisian police department. Now cut down to the limousine and wait for me, I’ll join you presently. And, Mr. Narkom?”

“Yes, old chap?”

“As you go out, give Dollops directions where and how to get to the scene of the tragedy, and tell him to follow us in a taxi as expeditiously as possible.”

“Oh, Molly ‘Awkins! There ain’t no rest for the wicked and no feedin’ for the ’ungry this side of Kensal Green and precious little on the other!” sighed Dollops when he received this message. “Not four weeks it ain’t since I was drug off in the middle of my lunch to go Cingalee huntin’ in Soho for them bounders wot was after Lady Chepstow’s ’Sacred Son,’ and now here I am pulled out of my blessed pajamas in the middle of the night to go ‘Tickle Tootsying’ in the bally fog at Wimbledon! Well, all right, sir. Where the gov’ner goes, I goes, bless his ’eart; so you can look for me as soon as I can get out of these Eytalian pants.”

Narkom made no comment; merely went down and out to the waiting limousine and took his seat in it, full of a racking, nervous impatience that was like a consuming fire; and there Cleek found him, ten minutes later, when he jumped in with his kit bag and gave the signal which set Lennard to speeding the car back on its way to the scene of the mysterious tragedy.

“Pull down the blinds and turn up the light, Mr. Narkom, so I can make a few necessary changes on the way,” he said, opening the locker and groping round in the depths of it as the limousine scudded around the corner and tore off up Picadilly. “You can give me the particulars of the case while I’m making up. Come on let’s have them. How did the affair begin, and where?”

Narkom detailed the occurrences of the night with the utmost clearness, from the moment when the shot and the cry attracted Lennard’s attention to that when the ghastly discovery was made in the semi-ruined cottage.

“Oho!” said Cleek, with one of his curious smiles. “So our friend the mysterious assassin disappeared in the middle of a sort of tunnel did he and with a man at either end? Hum-m-m! I see, I see!”

“Do you? Well, I’m blest if I do, then. There wasn’t a place as big as your hand to hide anything in, much less shelter a man; and the fellow who could do a diabolical thing like that ”

“That is a question which simply remains to be seen,” interposed Cleek. “The thing is not so supernatural as it appears at first blush. Once in the days that lie behind me, when I was the hunted and not the hunter in that old ‘Vanishing Cracksman’ time of mine, I myself did that ‘amazing disappearance’ twice. Once in an alley in New York when there was a night watchman and a patrolman to be eluded; and once in Paris when, with Margot’s lot, I was being hunted into a trap which would have been the end of one of the biggest coups of my career had I been nabbed that night.”

“Margot?” repeated Narkom. “Yes, I remember the Queen of the Apaches the woman with whom you used to consort. Said she’d get even with you when you turned down the old life and took sides with the law instead of against it, I recollect. And you tell me that in those old days you practised a trick such as this fellow did to-night?”

“Yes. Beat him at it if you will pardon the conceit for I vanished in the middle of a narrow passage with a sergeant de ville chasing me at one end and a concierge accompanied by a cabman and a commissionaire racing in at the other, I always fancied that that trick was original with me. I know of no one but Margot and her crew who were aware of the exploit, and if any man has borrowed a leaf from the book of those old times Oh, well, it will be the end of all your fears regarding any friend of ours, Mr. Narkom, for the fellow will stand convicted as a member of the criminal classes and, possibly, of Margot’s crew. We shall know the truth of that when we get to the scene of this mysterious vanishment, my friend.”

“Yes, but how was it done, Cleek? Where did he go? How did he elude the chasing keeper and the waiting constable? A man can’t vanish into thin air, and I tell you there wasn’t a place of any sort for him to hide in. Yet you speak of the trick as if it were easy.”

“It is easy, provided he had the same cause and adopted the same means as I did, my friend. Wait until we come to investigate that railway arch and you will see. Now tell me something, Mr. Narkom: How came you to be in the neighbourhood of Mulberry Lane at all to-night? It is nowhere near Clavering Close; and it was decidedly out of your way if, as you tell me, you were on the way back to town. It is peculiar that you should have chosen to go out of your way like that.”

“I didn’t choose to do it. As a matter of fact I was executing a commission for Lady Clavering. It appears that a jewel had been found by the maid-in-attendance lying upon the floor of the ladies’ room, and as Lady Clavering recollected seeing that jewel upon Miss Ailsa Lorne’s person to-night, she asked me to stop at Wuthering Grange and return it to her.”

“Ailsa Lorne!” A light flashed into Cleek’s face as he repeated the name, and rising into his eyes, made them positively radiant. “Ailsa Lorne, Mr. Narkom? You surely do not mean to tell me that Ailsa Lorne is in Wimbledon?”

“Yes, certainly I do. My dear fellow, how the name seems to interest you. But I remember: you know the lady, of course.”

Know her? Know the woman whose eyes had lit the way back from those old days of crime to the higher and the better things, the woman who had been his redemption in this world, and would, perhaps, be his salvation in the one to come? Cleek’s very soul sang hymns of glory at the bare thought of her.

“I did not know Miss Lorne would be in Wimbledon,” he said quietly, “or anywhere in the neighbourhood of London. I thought she had accepted a temporary position down in Suffolk as the companion of an old school friend, Lady Katharine Fordham.”

“So she did,” replied Narkom. “And it is as that unhappy young lady’s companion that she was at Clavering Close to-night. Lady Katharine, as you doubtless know, is Lord St. Ulmer’s only child.”

“Lord St. Ulmer?” repeated Cleek, gathering up his brows thoughtfully. “Hum-m-m! Ah-h-h! I seem to remember something about a Lord St. Ulmer. Let me see! Lost his wife when his daughter was a mere baby, didn’t he, and took the loss so much to heart that he went out to Argentina and left the girl to the care of an aunt? Yes, I recall it now. Story was in all the papers some months ago. Got hold of a silver mine out there; made a pot of money, and came home after something like fifteen years of absence; bought in the old family place, Ulmer Court, down in Suffolk, after it had been in the hands of strangers for a generation or two, and took his daughter down there to live. That’s the man, isn’t it?”

“Yes, that’s the man. He’s worth something like half a million sterling to-day lucky beggar.”

“Then why do you allude to his daughter and heiress as an ’unhappy young lady’? Surely with unlimited wealth at her command ”

“Which I dare say she would gladly give up to get back other things that she has lost,” interposed Mr. Narkom. “Her hopes of becoming young Geoff Clavering’s wife for one!”

“Young Geoff Clavering? The chap whose coming of age was celebrated to-day?”

“Yes, the son and heir of my friend, Sir Philip Clavering, as fine a boy as ever stood in shoe leather. He and Lady Katharine have almost grown up together, as her uncle and aunt, General and Mrs. Raynor, are close neighbours at Wuthering Grange. They were engaged at seventeen, a regular idyllic love match, old chap. Sir Philip and Lady Clavering were immensely fond of her and heartily approved the match. So apparently did her father, to whom she wrote, although she had not seen him since she was a baby. Even when he returned to England with a fortune big enough to warrant his daughter wedding a duke, he still appeared to approve of the engagement, and suggested that the wedding should be celebrated on the young man’s twenty-first birthday.”

“Which, as to-day is that day, and you still speak of her as Lady Katharine Fordham, I presume did not take place?”

“No, it did not. Some three months ago, a certain Count de Louvisan, an Austrian, appeared on the scene, claiming acquaintance with St. Ulmer; and it seems that after a subsequent interview, Lord St. Ulmer informed his daughter that her engagement with Geoff Clavering must come to an end, and that it was her father’s intention that she should become the wife of Count de Louvisan.”

“Oho!” said Cleek, in two different tones. “All of which goes to suggest that the count had some hold over the old gentleman and was using it to feather his own nest. Of course the girl couldn’t be compelled to marry the man against her will, so if she consented to the breaking of the engagement Did she?”

“Yes.”

“Then something must have been told her something which was either a lie or an appalling truth to make her take a step like that, for a woman does not break with the man she loves unless something more than life is at stake. And it is this Count de Louvisan, you tell me, that has been murdered? Hum-m-m!”

“Yes, the worst of it is,” said Mr. Narkom gloomily, “there was a scene between him and young Clavering but a couple of hours before the murder was discovered.”

“What’s that?” rapped out Cleek. “A ‘scene’! A quarrel do you mean? How and where? Or perhaps you don’t know?”

“As it happens, I do,” said Narkom, “for I happened to be at Clavering Close when it took place. You see, Lord St. Ulmer is laid up with a sprained ankle at Wuthering Grange, where he has been staying with his sister and brother-in-law, the Raynors. Lady Katharine seized the opportunity to say farewell to Geoff, and came over at about eight o’clock; and I hope, Cleek, I may never in my life again see anything so heartbreaking as was made those last few minutes of parting.”

“Few? Why few, pray?”

“Because they had not been together half an hour when the Count de Louvisan came over, posthaste, after his fiancee. Lady Katharine’s absence had been discovered from the Grange, and naturally he was the one who would come after her. You can guess what followed, Cleek. Young Clavering fairly flew at the fellow, and would have thrashed him but that his father and I got hold of him, and Hammond and Petrie hustled the count out of the room. But even so, nobody could prevent that wild, impetuous, excited boy from challenging the man, then and there. To that the count merely threw back a laugh and said, as Petrie and Hammond hustled him out of the room: ’Monsieur, one does not fight a fallen foe one merely pities him!’ And it took all his father’s strength and mine to hold the boy in check. ‘Pity yourself if ever I meet you!’ he shouted. ’There’ll be one blackguard the less in the world if ever I come within reach of you again, damn you! I had nine years of hope until you came, and I’ll put a mark on you for every one of them that you’ve spoilt!”

“’A mark’!” repeated Cleek, with some slight show of agitation. “A mark for every year? It is true that the barking dog is the last to bite but What were those figures that you tell me were smeared on the dead man’s shirt bosom 2-4-1-2, were they not? And that sum equals nine!”

“Yes,” said Narkom, with a sort of groan. “Just nine, Cleek, just exactly nine. That’s what cut the heart out of me when I saw that dead man spiked to the cottage wall, bearing the very mark he had sworn that he should bear.”

“I see,” murmured Cleek thoughtfully. “Of course, the wisest of men are sometimes mistaken, but somehow I took those numerals to stand for a sign of a secret society; but, as you say, the numbers do indeed total nine the years of young Clavering’s threat, but ”

His voice trailed off; he sat for a moment deep in thought.

“Then there is the ‘spike,’ that is an old Apache punishment. They spiked Lanisterre to the wall when he went over to the police. Which is it? The Apaches or this foolish, hot-headed boy lover?”

Narkom wisely refrained from comment. He knew the ways and methods of his famous ally only too well, and he sat silent therefore till Lennard pulled up the limousine sharply in front of Gleer Cottage.

“Here we are at the cottage unless you would like to see the arch first?”

“Oh, no,” Cleek smiled softly. “That part of the mystery, my friend, is quite simple. Lead the way, please.”

They alighted without further remark, and Narkom was followed by as complete a specimen of a French dandy as could be found in Paris, from the gardens of the Tuileries to the benches of the Luxembourg.
