defeat in his voice. 'Nothing has been disturbed;'—he swept his arm around comprehensively—'papers and so forth you can examine at leisure.'
Presently we quitted that house upon which the fateful Chinaman had set his seal, as the suburb was awakening to a new day. The clank of milk-cans was my final impression of the avenue to which a dreadful minister of death had come at the bidding of the death lord. We left Inspector Weymouth in charge and returned to my rooms, scarcely exchanging a word upon the way.
Nayland Smith, ignoring my entreaties, composed himself for slumber in the white cane chair in my study. About noon he retired to the bathroom, and returning, made a pretense of breakfast; then resumed his seat in the cane armchair. Carter reported in the afternoon, but his report was merely formal. Returning from my round of professional visits at half past five, I found Nayland Smith in the same position; and so the day waned into evening, and dusk fell uneventfully.
In the corner of the big room by the empty fireplace, Nayland Smith lay, with his long, lean frame extended in the white cane chair. A tumbler, from which two straws protruded, stood by his right elbow, and a perfect continent of tobacco smoke lay between us, wafted toward the door by the draught from an open window. He had littered the hearth with matches and tobacco ash, being the most untidy smoker I have ever met; and save for his frequent rapping-out of his pipe bowl and perpetual striking of matches, he had shown no sign of activity for the past hour. Collarless and wearing an old tweed jacket, he had spent the evening, as he had spent the day, in the cane chair, only quitting it for some ten minutes, or less, to toy with dinner.
My several attempts at conversation had elicited nothing but growls; therefore, as dusk descended, having dismissed my few patients, I busied myself collating my notes upon the renewed activity of the Yellow Doctor, and was thus engaged when the 'phone bell disturbed me. It was Smith who was wanted, however; and he went out eagerly, leaving me to my task.
At the end of a lengthy conversation, he returned from the 'phone and began, restlessly, to pace the room. I made a pretense of continuing my labors, but covertly I was watching him. He was twitching at the lobe of his left ear, and his face was a study in perplexity. Abruptly he burst out:
'I shall throw the thing up, Petrie! Either I am growing too old to cope with such an adversary as Fu-Manchu, or else my intellect has become dull. I cannot seem to think clearly or consistently. For the Doctor, this crime, this removal of Slattin, is clumsy—unfinished. There are two explanations. Either he, too, is losing his old cunning or he has been interrupted!'
'Interrupted!'
'Take the facts, Petrie,'—Smith clapped his hands upon my table and bent down, peering into my eyes—'is it characteristic of Fu-Manchu to kill a man by the direct agency of a snake and to implicate one of his own damnable servants in this way?'
'But we have found no snake!'
'Karamaneh introduced one in some way. Do you doubt it?'
'Certainly Karamaneh visited him on the evening of his death, but you must be perfectly well aware that even if she had been arrested, no jury could convict her.'
Smith resumed his restless pacings up and down.
'You are very useful to me, Petrie,' he replied; 'as a counsel for the defense you constantly rectify my errors of prejudice. Yet I am convinced that our presence at Slattin's house last night prevented Fu-Manchu from finishing off this little matter as he had designed to do.'
'What has given you this idea?'
'Weymouth is responsible. He has rung me up from the Yard. The constable on duty at the house where the murder was committed, reports that some one, less than an hour ago, attempted to break in.'
'Break in!'
'Ah! you are interested? I thought the circumstance illuminating, also!'
'Did the officer see this person?'
'No; he only heard him. It was some one who endeavored to enter by the bathroom window, which, I am told, may be reached fairly easily by an agile climber.'
'The attempt did not succeed?'
'No; the constable interrupted, but failed to make a capture or even to secure a glimpse of the man.'
We were both silent for some moments; then:
'What do you propose to do?' I asked.
'We must not let Fu-Manchu's servants know,' replied Smith, 'but to-night I shall conceal myself in Slattin's house and remain there for a week or a day—it matters not how long—until that attempt is repeated. Quite obviously, Petrie, we have overlooked something which implicates the murderer with the murder! In short, either by accident, by reason of our superior vigilance, or by the clumsiness of his plans, Fu-Manchu for once in an otherwise blameless career, has left a clue!'
Chapter 10 THE CLIMBER RETURNS
In utter darkness we groped our way through into the hallway of Slattin's house, having entered, stealthily, from the rear; for Smith had selected the study as a suitable base of operations. We reached it without mishap, and presently I found myself seated in the very chair which Karamaneh had occupied; my companion took up a post just within the widely opened door.
So we commenced our ghostly business in the house of the murdered man—a house from which, but a few hours since, his body had been removed. This was such a vigil as I had endured once before, when, with Nayland Smith and another, I had waited for the coming of one of Fu-Manchu's death agents.
Of all the sounds which, one by one, now began to detach themselves from the silence, there was a particular sound, homely enough at another time, which spoke to me more dreadfully than the rest. It was the ticking of the clock upon the mantelpiece; and I thought how this sound must have been familiar to Abel Slattin, how it must have formed part and parcel of his life, as it were, and how it went on now—tick-tick-tick-tick—whilst he, for whom it had ticked, lay unheeding—would never heed it more.
As I grew more accustomed to the gloom, I found myself staring at his office chair; once I found myself expecting Abel Slattin to enter the room and occupy it. There was a little China Buddha upon the bureau in one corner, with a gilded cap upon its head, and as some reflection of the moonlight sought out this little cap, my thoughts grotesquely turned upon the murdered man's gold tooth.
Vague creakings from within the house, sounds as though of stealthy footsteps upon the stair, set my nerves tingling; but Nayland Smith gave no sign, and I knew that my imagination was magnifying these ordinary night sounds out of all proportion to their actual significance. Leaves rustled faintly outside the window at my back: I construed their sibilant whispers into the dreaded name—Fu-Manchu-Fu-Manchu—Fu-Manchu!
So wore on the night; and, when the ticking clock hollowly boomed the hour of one, I almost leaped out of my chair, so highly strung were my nerves, and so appallingly did the sudden clangor beat upon them. Smith, like a man of stone, showed no sign. He was capable of so subduing his constitutionally high-strung temperament, at times, that temporarily he became immune from human dreads. On such occasions he would be icily cool amid universal panic; but, his object accomplished, I have seen him in such a state of collapse, that utter nervous exhaustion is the only term by which I can describe it.
Tick-tick-tick-tick went the clock, and, with my heart still thumping noisily in my breast, I began to count the tickings; one, two, three, four, five, and so on to a hundred, and from one hundred to many hundreds.
Then, out from the confusion of minor noises, a new, arresting sound detached itself. I ceased my counting; no longer I noted the tick-tick of the clock, nor the vague creakings, rustlings and whispers. I saw Smith, shadowly, raise his hand in warning—in needless warning, for I was almost holding my breath in an effort of acute listening.
From high up in the house this new sound came from above the topmost room, it seemed, up under the roof; a regular squeaking, oddly familiar, yet elusive. Upon it followed a very soft and muffled thud; then a metallic sound as of a rusty hinge in motion; then a new silence, pregnant with a thousand possibilities more eerie than any clamor.
My mind was rapidly at work. Lighting the topmost landing of the house was a sort of glazed trap, evidently
