And I reflected that the best men at New Scotland Yard had failed to pick up the slightest clue!

"The Hashishin, of whom that dreadful man is leader, are rich, or have supporters who are rich. The plan was to make them pay for the slipper."

"My G.o.d! it was playing with fire!"

She sat silent awhile. Emotion threatened to get the upper hand.

Then--

"Two days ago," she almost whispered, "he set out--to ... get the slipper!"

"To steal it?"

"To steal it!"

"From Ha.s.san of Aleppo?"

I could scarcely believe that any man, single-handed, could have had the hardihood to attempt such a thing.

"From Ha.s.san, yes!"

I faced her, amazed, incredulous.

"Dexter had suffered mutilation, he knew that the Hashishin sought his life for his previous attempts upon the relic of the Prophet, and yet he dared to venture again into the very lions' den?"

"He did, Mr. Cavanagh, two days ago. And--"

"Yes?" I urged, as gently as I could, for she was shaking pitifully.

"He never came back!"

The words were spoken almost in a whisper. She clenched her hands and leapt from the chair, fighting down her grief and with such a stark horror in her beautiful eyes that from my very soul I longed to be able to help her.

"Mr. Cavanagh" (she had courage, this bewildering accomplice of a cracksman), "I know the house he went to! I cannot hope to make you understand what I have suffered since then. A thousand times I have been on the point of going to the police, confessing all I knew, and leading them to that house! O G.o.d! if only he is alive, this shall be his last crooked deal--and mine! I dared not go to the police, for his sake! I waited, and watched, and hoped, through two such nights and days ... then I ventured. I should have gone mad if I had not come here. I knew you had good cause to hate, to detest me, but I remembered that you had a great grievance against Ha.s.san. Not as great, O heaven! not as great as mine, but yet a great one. I remembered, too, that you were the kind of man--a woman can come to..."

She sank back into the chair, and with her fingers twining and untwining, sat looking dully before her.

"In brief," I said, "what do you propose?"

"I propose that we endeavour to obtain admittance to the house of Ha.s.san of Aleppo--secretly, of course, and all I ask of you in return for revealing the secret of its situation is--"

"That I let Dexter go free?"

Almost inaudibly she whispered: "If he lives!"

Surely no stranger proposition ever had been submitted to a law-abiding citizen. I was asked to connive in the escape of a notorious criminal, and at one and the same time to embark upon an expedition patently burglarious! As though this were not enough, I was invited to beard Ha.s.san of Aleppo, the most dreadful being I had ever encountered East or West, in his mysterious stronghold!

I wondered what my friend, Inspector Bristol, would have thought of the project; I wondered if I should ever live to see Ha.s.san meet his just deserts as a result of this enterprise, which I was forced to admit a foolhardy one. But a man who has selected the career of a war correspondent from amongst those which Fleet Street offers, is the victim of a certain craving for fresh experiences; I suppose, has in his character something of an adventurous turn.

For a while I stood staring from the window, then faced about and looked into the violet eyes of my visitor.

"I agree, Carneta!" I said.

CHAPTER XXIX

WE MEET MR. ISAACS

Quitting the wayside station, and walking down a short lane, we came out upon Watling Street, white and dusty beneath the afternoon sun.

We were less than an hour's train journey from London but found ourselves amid the Kentish hop gardens, amid a rural peace unbroken.

My companion carried a camera case slung across her shoulder, but its contents were less innocent than one might have supposed. In fact, it contained a neat set of those instruments of the burglar's art with whose use she appeared to be quite familiar.

"There is an inn," she said, "about a mile ahead, where we can obtain some vital information. He last wrote to me from there."

Side by side we tramped along the dusty road. We both were silent, occupied with our own thoughts. Respecting the nature of my companion's I could entertain little doubt, and my own turned upon the foolhardy nature of the undertaking upon which I was embarked.

No other word pa.s.sed between us then, until upon rounding a bend and pa.s.sing a cl.u.s.ter of picturesque cottages, the yard of the Vinepole came into view.

"Do they know you by sight here?" I asked abruptly.

"No, of course not; we never made strategic mistakes of that kind.

If we have tea here, no doubt we can learn all we require."

I entered the little parlour of the inn, and suggested that tea should be served in the pretty garden which opened out of it upon the right.

The host, who himself laid the table, viewed the camera case critically.

"We get a lot of photographers down here," he remarked tentatively.

"No doubt," said my companion. "There is some very pretty scenery in the neighbourhood."

The landlord rested his hands upon the table.

"There was a gentleman here on Wednesday last," he said; "an old gentleman who had met with an accident, and was staying somewhere hereabouts for his health. But he'd got his camera with him, and it was wonderful the way he could use it, considering he hadn't got the use of his right hand."

"He must have been a very keen photographer," I said, glancing at the girl beside me.

"He took three or four pictures of the Vinepole," replied the landlord (which I doubted, since probably his camera was a dummy); "and he wanted to know if there were any other old houses in the neighbourhood. I told him he ought to take Cadham Hall, and he said he had heard that the Gate House, which is about a mile from here, was one of the oldest buildings about."

A girl appeared with a tea tray, and for a moment I almost feared that the landlord was about to retire; but he lingered, whilst the girl distributed the things about the table, and Carneta asked casually, "Would there be time for me to photograph the Gate House before dark?"

"There might be time," was the reply, "but that's not the difficulty.

Mr. Isaacs is the difficulty."

"Who is Mr. Isaacs?" I asked.

"He's the Jewish gentleman who bought the Gate House recently. Lots of money he's got and a big motor car. He's up and down to London almost every day in the week, but he won't let anybody take photographs of the house. I know several who've asked."
