And then an angel with a burning sword came and scourged me out of my Eden. And the angel was Burton, and the sword was a dripping umbrella.

"I hate to take you out," he said. "The bottom's dropped out of the sky; but I want you to make a little experiment with me." He caught sight of Margery through the portieres, and the imp of mischief in him prompted his next speech. "She said she must see you," he said, very distinctly, and leered at me.

"Don't be an a.s.s," I said angrily. "I don't know that I care to go out to-night."

He changed his manner then.

"Let's go and take a look at the staircase you fellows have been talking about," he said. "I don't believe there is a staircase there, except the main one. I have hounded every politician in the city into or out of that joint, and I have never heard of it."

I felt some hesitation about leaving the house--and Margery--after the events of the previous night. But Margery had caught enough of the conversation to be anxious to have me to go, and when I went in to consult her she laughed at my fears.

"Lightning never strikes twice in the same place," she said bravely. "I will ask Katie to come down with me if I am nervous, and I shall wait up for the family."

I went without enthusiasm. Margery's departure had been delayed for a day only, and I had counted on the evening with her. In fact, I had sent the concert tickets to Edith with an eye single to that idea. But Burton's plan was right. It was, in view of what we knew, to go over the ground at the White Cat again, and Sat.u.r.day night, with the place full of men, would be a good time to look around, unnoticed.

"I don't hang so much to this staircase idea," Burton said, "and I have a good reason for it. I think we will find it is the warehouse, yet."

"You can depend on it, Burton," I maintained, "that the staircase is the place to look. If you had seen Wardrop's face to-day, and his agony of mind when he knew he had a.s.sociated 'staircase' with 'shot,' you would think just as I do. A man like Schwartz, who knew the ropes, could go quietly up the stairs, unbolt the door into the room, shoot Fleming and get out. Wardrop suspects Schwartz, and he's afraid of him. If he opened the door just in time to see Schwartz, we will say, backing out the door and going down the stairs, or to see the door closing and suspect who had just gone, we would have the whole situation, as I see it, including the two motives of deadly hate and jealousy."

"Suppose the stairs open into the back of the room? He was sitting facing the window. Do you think Schwartz would go in, walk around the table and shoot him from in front? Pooh! Fudge!"

"He had a neck," I retorted. "I suppose he might have turned his head to look around."

We had been walking through the rain. The White Cat, as far off as the poles socially, was only a half-dozen blocks actually from the best residence portion of the city. At the corner of the warehouse, Burton stopped and looked up at it.

"I always get mad when I look at this building," he said. "My great grandfather had a truck garden on this exact spot seventy years ago, and the old idiot sold out for three hundred dollars and a pair of mules!

How do you get in?"

"What are you going in for?" I asked.

"I was wondering if I had a grudge--I have, for that matter--against the mayor, and I wanted to shoot him, how I would go about it. I think I should find a point of vantage, like an overlooking window in an empty building like this, and I would wait for a muggy night, also like this, when the windows were up and the lights going. I could pot him with a thirty-eight at a dozen yards, with my eyes crossed."

We had stopped near the arched gate where I had stood and waited for Hunter, a week before. Suddenly Burton darted away from me and tried the gate. It opened easily, and I heard him splashing through a puddle in the gloomy yard.

"Come in," he called softly. "The water's fine."

The gate swung to behind me, and I could not see six inches from my nose. Burton caught my elbow and steered me, by touching the fence, toward the building.

"If it isn't locked too tight," he was saying, "we can get in, perhaps through a window, and get up-stairs. From there we ought to be able to see down into the club. What the devil's that?"

It was a rat, I think, and it scrambled away among the loose boards in a frenzy of excitement. Burton struck a match; it burned faintly in the dampness, and in a moment went out, having shown us only the approximate location of the heavy, arched double doors. A second match showed us a bar and a rusty padlock; there was no entrance to be gained in that way.

The windows were of the eight-paned variety, and in better repair than the ones on the upper floors. By good luck, we found one unlocked and not entirely closed; it shrieked hideously as we pried it up, but an opportune clap of thunder covered the sound.

By this time I was ready for anything that came; I was wet to my knees, muddy, disreputable. While Burton held the window I crawled into the warehouse, and turned to perform the same service for him. At first I could not see him, outside. Then I heard his voice, a whisper, from beyond the sill.

"Duck," he said. "Cop!"

I dropped below the window, and above the rain I could hear the squash of the watchman's boots in the mud. He flashed a night lamp in at the window next to ours, but he was not very near, and the open window escaped his notice. I felt all the nervous dread of a real malefactor, and when I heard the gate close behind him, and saw Burton put a leg over the sill, I was almost as relieved as I would have been had somebody's family plate, tied up in a tablecloth, been reposing at my feet.

Burton had an instinct for getting around in the dark. I lighted another match as soon as he had closed the window, and we made out our general direction toward where the stairs ought to be. When the match went out, we felt our way in the dark; I had only one box of wax matches, and Burton had dropped his in a puddle.

We got to the second floor, finally, and without any worse mishap than Burton banging his arm against a wheel of some sort. Unlike the first floor, the second was subdivided into rooms; it took a dozen precious matches to find our way to the side of the building overlooking the club, and another dozen to find the window we wanted. When we were there at last, Burton leaned his elbows on the sill, and looked down and across.

"Could anything be better!" he said. "There's our theater, and we've got a proscenium box. That room over there stands out like a spot-light."

He was right. Not more than fifteen feet away, and perhaps a foot lower than our window, was the window of the room where Fleming had been killed. It was empty, as far as we could see; the table, neat enough now, was where it had been before, directly under the light. Any one who sat there would be an illuminated target from our window. Not only that, but an arm could be steadied on the sill, allowing for an almost perfect aim.

"Now, where's your staircase?" Burton jeered.

The club was evidently full of men, as he had prophesied. Above the rattle of the rain came the thump--thump of the piano, and a half-dozen male voices. The shutters below were closed; we could see nothing.

I think it was then that Burton had his inspiration.

"I'll bet you a five-dollar bill," he said, "that if I fire off my revolver here, now, not one of those fellows down there would pay the slightest attention."

"I'll take that bet," I returned. "I'll wager that every time anybody drops a poker, since Fleming was shot, the entire club turns out to investigate."

In reply Burton got out his revolver, and examined it by holding it against the light from across the way.

"I'll tell you what I'll do," he said. "Everybody down there knows me; I'll drop in for a bottle of beer, and you fire a shot into the floor here, or into somebody across, if you happen to see any one you don't care for. I suggest that you stay and fire the shot, because if you went, my friend, and n.o.body heard it, you would accuse me of shooting from the back of the building somewhere."

He gave me the revolver and left me with a final injunction.

"Wait for ten minutes," he said. "It will take five for me to get out of here, and five more to get into the club-house. Perhaps you'd better make it fifteen."

CHAPTER XXII

IN THE ROOM OVER THE WAY

He went away into the darkness, and I sat down on an empty box by the window and waited. Had any one asked me, at that minute, how near we were to the solution of our double mystery, I would have said we had made no progress--save by eliminating Wardrop. Not for one instant did I dream that I was within less than half an hour of a revelation that changed my whole conception of the crime.

I timed the interval by using one of my precious matches to see my watch when he left. I sat there for what seemed ten minutes, listening to the rush of the rain and the creaking of a door behind me In the darkness somewhere, that swung back and forth rustily in the draft from the broken windows. The gloom was infinitely depressing; away from Burton's enthusiasm, his scheme lacked point; his argument, that the night duplicated the weather conditions of that other night, a week ago, seemed less worthy of consideration.

Besides, I have a horror of making myself ridiculous, and I had an idea that it would be hard to explain my position, alone in the warehouse, firing a revolver into the floor, if my own argument was right, and the club should rouse to a search. I looked again at my watch; only six minutes.

Eight minutes.

Nine minutes.

Every one who has counted the pa.s.sing of seconds knows how they drag.

With my eyes on the room across, and my finger on the trigger, I waited as best I could. At ten minutes I was conscious there was some one in the room over the way. And then he came into view from the side somewhere, and went to the table. He had his back to me, and I could only see that he was a large man, with ma.s.sive shoulders and dark hair.

It was difficult to make out what he was doing. After a half-minute, however, he stepped to one side, and I saw that he had lighted a candle, and was systematically reading and then burning certain papers, throwing the charred fragments on the table. With the same glance that told me that, I knew the man. It was Schwartz.
