"Where are you," I countered. "Or rather, where have you been?"

"Getting a bar to pry off these boards."

"A bar?" I echoed stupidly.

"A crowbar from the shed. These planks will have to come off to let us in."

"The devil you say!" I was exasperated. "There's some one in here now--or was a minute back. Show me the other way in."

I heard the ring of the steel bar as its end hit the hard graveled path.

"Some one in there? Jerry, you're seeing things."

"Sure I am," I agreed drily. "But you get me to that other door quick!"

"The only other door is locked. I tried it from the garage. You're dreaming."

For reply, I ran up to the door and thrust my fist through the canvas, ripping it away from its clumsy tacking.

"Who's in there?" I cried. "Answer me!"

Dead silence; then a click as Worth snapped on a flood of light from his pocket torch, saying tolerantly, tiredly,

"I told you there was no one. There couldn't be."

"I tell you, Worth, there was. I saw the shadow on the square of that canvas. Give me the torch."

I pushed the flashlight through the opening and played the light cone about the room in a quick survey; then brought the circle of white glow to rest upon one of the side walls; and my hand went down and back to grip fingers about the b.u.t.t of my revolver. There was, as Worth had said, but one other door to this room; but more, there was apparently no other exit; no windows, no breaks in the walls. My circle of light was on this second door; and the very heart of that circle was a heavy steel bolt on the door, the bar of which was firmly shot into the socket on the frame. The only exit from that room, other than the door through which I now leaned with pistol raised, was locked--bolted from the inside!

Worth was crowding his big frame into the opening beside me.

"Keep back," I growled. "Some one's inside," and I sent the light shaft into corners to drive out the shadows, to cut in under the desk and chairs. Worth's reply was a laugh, and his arm went by me to reach inside the door. Then, as his fingers found the b.u.t.ton, a light sprang out from a lamp upon the center desk.

"You're letting your nerves play the deuce with you, Jerry," he said lightly. "Make way for my crowbar and we'll get in out of the wet."

I made no answer, but for a long moment more I searched that room with my eyes; but it was the kind you see all over at a glance. Big, square, plain, it hadn't a window in it; the walls, lined with book shelves, floor to ceiling; a fireplace; a library table with drawers; a few chairs. No chance for a hideout. I glanced at the ceiling and confirmed the evidence of my eyes. There was a skylight, and through it had come that curious glow that first attracted my attention to the place.

Then I gave Worth room to wield his tools on the barred door, while I ran quickly back to the house, into the kitchen, and plumped down in the chair where I had sat before. The light showed on the fog, brightened and dimmed as the mist drifted past. There was no possibility of a mistake: some one had been in the study, had turned on the table lamp, had projected his shadow against the patched panel of the door, and had somehow left the room, one door bolted, the only other exit barred and nailed.

I went back and rejoined Worth who was standing where a brownish stain on the rug marked a spot a little nearer the corner of the table than it was to the outer door. A curious place for a suicide to fall. Behind the table was the library chair in which Thomas Gilbert worked when at his desk; beside it a small cabinet with a humidor on its top and the open door below revealing several decanters and bottles, whisky and wine gla.s.ses, a tray; between the desk and the fireplace were two other chairs, large and comfortable; but in front of the table--between it and the door--was barren floor.

It is a fact that most men who shoot themselves do so while sitting; some lying in a bed; few standing. The psychology of this I must leave to others, but experience has taught me to question the suicide of one who has seemingly placed the muzzle of a revolver against him while on his feet. Thomas Gilbert had stood; had chosen to take his life as he was walking from door to desk, or from desk to door.

"Worth," I said. "There was somebody in here just now."

"Couldn't have been, Jerry," he answered absently; then added, his eyes on that stain, "I never could calculate what my father would do. But when I talked to him last night, right here in this room, he didn't seem to me a man ready to take his own life."

"You quarreled?"

"We always quarreled, whenever we met."

"But this quarrel was more bitter than usual?"

"The last quarrel would seem the bitterest, wouldn't it, Jerry?" he asked. Then, after a moment, "Poor Jim Edwards!"

I caught my tongue to hold back the question. Worth went on,

"When I phoned him just now, he hadn't heard a word about it. Seemed terribly upset."

"Hadn't heard?" I echoed. "How was that?"

"You know we saw him at Tait's last night. He took the Pacheco Pa.s.s road from San Francisco; drove straight to his ranch without hitting Santa Ysobel."

I wanted another look at that man Edwards. I was to have it. Worth went on absently,

"He'll be along presently to stay here while I'm away Monday. Told me it would be the first time he'd put foot in the house for four years. As boys up in Sonoma county, he and father always disagreed, but sometime these last years there was a big split over something. They were barely on speaking terms--and good old Jim took my news harder than as though I'd been telling him the death of a near friend."

"Works like that with us humans," I nodded. "Let some one die that you've disagreed with, and you remember every row you ever had with them; remember it and regret it--which is foolish."

"Which is foolish," Worth repeated, and seemed for the first time able to get away from the spot at which he had stopped.

He went over to the empty, fireless hearth and stood there, his back to the room, elbows on the mantel propping his head, face bent, oblivious to anything that I might do. It oughtn't to be hard to find the way this place could be entered and left by a man solid enough to cast a shadow, with quick fingers to snap the light on and off. But when I made a painstaking examination of a corner grate with a flue too small for anything but a chimney swallow to go up and down, a ceiling solidly beamed and paneled, the gla.s.s that formed the skylight set in firmly as part of the roof, when I'd turned up rugs and inspected an unbroken floor, even tried the corners of book cases to see if they masked a false entrance, I owned myself, for the moment, beaten there.

"Give me your torch--or go with me, Worth," I said. "I'd like to take a scoot around outside."

He didn't speak, only indicated the flashlight by a motion, where it lay on the shelf beside his hand. I took it, unbolted the door, and stepped into the garage.

Everything all right here. My roadster; a much handsomer small machine beyond it; a bench, portable forge and drill made a repair shop of one corner, and as my light flashed over these, I checked and stared. Why had Worth gone to the shed hunting a crowbar to open the door? Here were tools that would have served as well. I put from me the hateful thought, and d.a.m.ned c.u.mmings and his suspicions. The shadow didn't have to be Worth. Certainly he had not first lit that lamp, for I had seen it from the kitchen with him beside me. Some one other than Worth had been in there when Worth put up the roadster. I'd find the man it really was.

But even as I crossed to Eddie Hughes's door, something at the back of my head was saying to me that Worth could have been in that room--that there was time for it to be, if he had taken the crowbar from the garage and not from the shed as he said he did.

At this I took myself in hand. The lie would have been so clumsy a one that there was no way but to accept this statement for the truth; and some one else had made that shadow on the canvas.

I tried the chauffeur's door and found it locked; called, shook it, and had set my shoulder against it to burst it in, when the rolling door on the street side moved a little, and a voice said,

"H-y-ah! What you doin' there?"

I turned and flashed my light on the six-inch crack of the sliding door.

It gave me a strip of man, a long drab face at top, solid, meaty looking, yet somehow slightly cadaverous, a half shut eye, a crooked mouth--if I'd met that mug in San Francisco, I'd have labeled it "tough," and located it South of Market Street.

Slowly, it seemed rather reluctantly, Eddie Hughes worked the six-inch crack wider by working himself through it.

"What the h.e.l.l do you want in my room for?" he demanded. The form of the words was truculent, but the words themselves slid in a sort of spiritless fashion from the corner of that crooked mouth of his, and he added in the next breath, "I'll open up for you, when I've lit the blinks."

There was a central lamp that made the whole place as bright as day.

Eddie fumbled a key out of his pocket, threw the door of his room open, and stepped back to let me pa.s.s him.

"Capehart tells me Worth's here," he said as we went in.
