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 Saturday 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 associated '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.
