All in a moment a light seemed to break over Cleek's brain. The missing link had been supplied--the one thing that could make possible the wild thought which had come to him last night had been given into his hands.

Here at last was the key to the amazing mystery! He turned without a word and went with Arjeeb Noosrut.

"What an a.s.s!" he said to himself in the soundless words of thought.

"What an a.s.s never to have suspected it when it is all so clear!"

Meantime Ailsa and the boy, dismissed from any further need of service, walked on through the deepening dusk and turned their faces homeward.

But they had not gone twenty yards from the spot where Cleek had seen them last when the little boy set up a joyful cry and pointed excitedly to a claret-coloured limousine which at that moment swung in from the middle of the roadway and slowed down as it neared the kerb.

"Oh, look, Miss Lorne; here's mummie's motor-car; and I do believe that's Bimbi peeping out of it!" exclaimed the child--"Bimbi" being his pet name for Captain Hawksley--then broke, in wild excitement, from Ailsa's detaining hand and fled to a tall, military-looking man with a fair beard and moustache who had just that moment alighted from the vehicle. "It is Bimbi--it is!--it is!" he shouted as he ran. "Oh, Bimbi, I _am_ glad!"

"Ceddie, dear, you mustn't be so boisterous!" chided Ailsa, coming up with him at the kerb. "How fond he is of you to be sure, Captain Hawksley. You've come for us, I suppose? Ceddie recognized the car at once."

"Yes; jump in," he answered. "Lady Chepstow sent me after you. She's nervous, poor soul, every moment the boy's away from her. Jump in, old chap! Better take the back seat, Miss Lorne; it's more comfortable.

Quite settled, both of you? That's good. All right, chauffeur--Home!"

Then he jumped in after them, closed the door, dropped into a seat, and the motor, making a wide curve out into the road, pelted away into the fast-gathering darkness.

"Bimbi says maybe he's going to be my daddy one day--didn't you, Bimbi?"

said his little lordship, climbing up on to "Bimbi's" knee and snuggling close to him.

"I say, you know, you mustn't tell secrets, old chap!" was the laughing response. "Miss Lorne will hand you over to Nursie with orders to put you to bed if you do, I know. Won't you, Miss Lorne?"

"He ought to be in bed, anyhow," responded Ailsa gaily; and then, this giving the conversation a merry turn, they talked and laughed and kept up such a chatter that three-quarters of an hour went like magic and n.o.body seemed aware of it. But suddenly Ailsa thought, and then put her thoughts into words.

"What a long time we are in getting home," she said, and bent forward so that the light from the window might fall upon the dial of her wrist watch, then gave a little startled cry and half rose from her seat. For the darkness was now tempered by moonlight and she could see that they were no longer in the populous districts of the town, but were speeding along past woodlands and open fields in the very depths of the country.

"Good gracious! Johnston must have lost his senses!" she exclaimed agitatedly. "Look where we are, Captain Hawksley!--out in the country with only a farmhouse or two in sight. Johnston! Johnston!" She bent forward and rapped wildly on the gla.s.s panel. "Johnston, stop!--turn round!--are you out of your head? Captain Hawksley, stop him--stop him, for pity's sake!"

"Sit down, Miss Lorne." He made reply in a low, level voice, a voice in which there was something that made her pluck the child to her and hold him tight to her breast. "You are not going home to-night. You are going for a ride with me; and if---- Oh, that's your little game, is it?"

lurching forward as she made a frantic clutch at the handle of the door.

"Sit down, do you hear me?--or it will be worse for you! There!"--the cold bore of a revolver barrel touched her temple and wrung a quaking gasp of terror from her--"Do you feel that? Now you sit down and be quiet! If you make a single move, utter a single cry, I'll blow your brains out before you've half finished it! Look here, do you know who you're dealing with now? See!"

His hand reached up and twitched away the fair beard and moustache; he bent forward so that the moonlight through the gla.s.s could fall on his face. It had changed as his voice had now changed, and she saw that she was looking at the man who in those other days of stress and trial had posed as "Gaston Merode," brother to the fict.i.tious "Countess de la Tour."

"You!" she said in a bleak voice of desolation and fright. "Dear heaven, that horrible Margot's confederate, the King of the Apaches!"

"Yes!" he rapped out. "You and that fellow Cleek came between us in one promising game, but I'm hanged if you shall do it in this one! I want this boy, and--I've got him. Now, you call off Cleek and tell him to drop this case, to make no effort to follow us or to come between us and the kid, or I'll slit your throat after I've done with his little lordship here. Lanisterre!"--to the chauffeur--"Lanisterre, do you hear?"

"_Oui, monsieur._"

"Give her her head and get to the mill as fast as you can. Margot will be with us in another two hours' time."

III

Through the ever-deepening dusk Cleek and Arjeeb Noosrut moved onward together; and onward behind them moved, too, the same dilatory messenger boy who had loitered about in the neighbourhood of the Park, squandering his halfpence now as then, leaving a small trail of winkle sh.e.l.ls and trotter bones to mark the record of his pa.s.sage, and never seeming to lose one iota of his appet.i.te, eat as much and as often as he would.

The walk led down into the depths of Soho, that refuge of the foreign element in London; but long before they halted at the narrow doorway of a narrow house in a narrow side street that seemed to have gone to sleep in an atmosphere of gloom and smells Cleek had adroitly "pumped" Arjeeb Noosrut dry, and the riddle of the sacred son was a riddle to him no longer. He was now only anxious to part from the man and return with the news to Lady Chepstow, and was casting round in his mind for some excuse to avoid going indoors with him to waste precious time in breaking bread and eating salt. Suddenly there lurched out of an adjoining doorway an ungainly figure in turban and sandals and the full flower of that grotesque regalia which pa.s.ses muster at cheap theatres and masquerade b.a.l.l.s for the costume of a Cingalese. The fellow had bent forward out of the deeper darkness of the house-pa.s.sage into the murk and gloom of the ill-lit street, and was straining his eyes as if in search for some one long expected.

"Dog of an infidel!" exclaimed Arjeeb Noosrut, speaking in Hundustani and spitting on the pavement as he caught sight of the man. "See, well-beloved, he is of those 'others' of which I spoke when I first met thee. There are many of them, but true believers none. They dwell in a room huddled up as unclean things in the house there; they drink and make merry far into the night, and a woman veiled and in European garb comes to them and drinks with them. Sometimes a man of her kind is with her, and they speak a tongue that is not the tongue of our people; yet have I seen them go forth into the city and do homage as we to the sacred son."

Cleek sucked in his breath and, twitching round, stared at the dim figure leaning forward in the dim light.

"By George!" he said to himself; "if I know anything, I ought to know the slouch and the low-sunk head of the Apache! And a woman comes! And a man comes! And there are five lacs of rupees! I wonder! I wonder! But no--she wouldn't come here, to a place like this, if she had ventured back into England and had called some of the band over to help. She'd go to the old spot where she and I used to lie low and laugh whilst the police were hunting for me. She'd go there, I'm sure, to the old Burnt Acre Mill, where, if you were 'stalked,' you could open the sluice gates and let the Thames and the mill stream rush in and meet, and make a h.e.l.l of whirling waters that would drown a fish. She would go there if it were she. And yet--it is an Apache: I swear it is an Apache!"

He turned and looked back at Arjeeb Noosrut, then raised his hand and brushed it down the back of his head, which was always the sign "Wait!"

to Dollops, and then spoke as calmly as he could.

"Brother, I will go in and break bread and eat salt with thee," he said.

"But I may do no more, for to-night I am in haste."

"Come, then," the man answered; and taking him by the hand, led him in and up to a room at the back of the second storey, where, hot as the night was, the windows were closed and a woman, squatted before a lighted brasier, was dripping the contents of an oil cruse over the roasting carcase of a young kid.

"It is to shut out the sounds of the vile infidel orgies from the house adjoining," explained Arjeeb Noosrut, as Cleek walked to the tightly closed window and leant his forehead against it. "Yet, if the heat oppresses thee----"

"It does," interposed Cleek, and leant far out into the darkness as though sucking in the air when the sash was raised and the thing which had been only a dim babel of wordless sounds a moment before became now the riotous laughter and the ribald comments of men upon the verses of a comic song which one of their number was joyously singing.

"French!" said Cleek under his breath, as he caught the notes of the singer and the words of his audience, "French--I knew it!"

Then he drew in his head, and having broken of the bread and eaten of the salt which, at a word from Arjeeb Noosrut, the woman brought on a wicker tray and laid before them, he moved hastily to the door.

"Brother and son of the faithful, peace be with thee, I must go," he said. "But I come again; and it is written that thou shalt be honoured above all men when I return to thee, and that the true believers--the true sons of Holy Buddha--shall have cause to set thy name at the head of the records of those who are most blest of him!"

Then he salaamed and pa.s.sed out. Closing the door behind him, he ran like a hare down the narrow stairs. At the door Dollops rose up like the imp in a pantomime and jumped toward him.

"Law, guv'ner, I'm nigh starved a-waitin' for yer!" he said in a whisper. "Wot's the lay now? A double quick change? I've got the stuff here, look!"--holding up the package he was carrying--"or a chance for me to do some fly catchin' with me bloomin' tickle tootsies?"

The man in the Cingalese costume had vanished from the doorway of the adjoining house, and, catching the boy by the arm, Cleek hurried him to it and drew him into the dark pa.s.sage.

"I'm going to the back; I'm going to climb up to the windows of the second storey and see who's there and what's going on," he whispered.

"Lie low and watch. I think it's Margot's gang."

"Oh, colour me blue! Them beauties? And in London? I'd give a tanner for a strong cup o' tea!"

"Shh-h! Be quiet--speak low. Don't be seen, but keep a close watch; and if anybody comes downstairs----"

"He's mine!" interjected Dollops, stripping up his sleeves. "Glue to the eyebrows and warranted to stick! Nip away, guv'ner, and leave it to the tickle tootsies and me!" Then, as Cleek moved swiftly and silently down the pa.s.sage and slipped out into the sort of yard at the back of the house, he pulled out his roll of brown paper squares and his tube of adhesive, and crawling upstairs on his hands and knees, began operations at the top step. But he had barely got the first "plaster" fairly made and ready to apply when there came a rush of footsteps behind him and he was obliged to duck down and flatten himself against the floor of the landing to escape being run down by a man who dashed in through the lower door, flew at top speed up the stairs and, with a sort of blended cheer and yell, whirled open a door on the landing above and vanished.

In a twinkling other cheers rang out, there was the sound of hastily moving feet and the uproar of general excitement.

"Oh, well, if you won't stop to be waited on, gents, help yourselves!"

said Dollops with a chuckle. Then he began backing hastily down the stairs, squirting the contents of the tube all over the steps, and concluded the operation by scattering all the loose sheets of paper on the floor at the foot of them before slipping out into the street and composedly waiting.

Meantime Cleek, sneaking out through the rear door, found himself in a small, brick-paved yard hemmed in by a high wall thickly fringed on the top with a hedge of broken bottles. At one time in its history the house had been occupied by a catgut maker, and the rickety shed in which he had carried on his calling still clung, sagging and broken-roofed, to the building itself, its rotten slates all but vanished, and its interior piled high with mildewed bedding, mouldy old carpet, broken furniture, and refuse of every sort.

A foot or two above the roof-level of this glowed--two luminous rectangles in the blackness of darkness--the windows of the back room on the second storey; and out of these came floating still the song, the laughter, and the jabbered French he had heard in the house next door.

It did not take him long to make up his mind. Gripping the swaying supports of the sagging shed, he went up it with the agility of a monkey, crawled to the nearer of the two windows, and, cautiously raising himself, peeped in. What he saw made him suck in his breath sharply and sent his heart hammering hard and fast.

A dozen men were in the room, men whose faces, despite an inartistic attempt to appear Oriental, he recognized at a glance and knew better than he knew his own. About them lay discarded portions of Cingalese attire, thrown off because of the heat, and waiting to be resumed at any moment. The air was thick with tobacco smoke and rank with spirituous odours. Sprawled figures were everywhere, and on a sort of couch against the opposite wall, a cigarette between her fingers, a gla.s.s of absinthe at her elbow, her laughter and badinage ringing out as loudly as any, lay the lissom figure of Margot!

But even as Cleek looked in upon it the picture changed. Swift, sharp, and sudden came the rattle of flying feet on the outer stairs. Margot flung aside her cigarette and jumped up, the song and the laughter came to an abrupt end, the door flew open, and with a shout and a cheer a man bounced into the room.
