“Fosdick said the same thing without having many facts. How could a right-handed man shoot himself behind the left ear? How could he do a thing like that and then get rid of the weapon without leaving a trace of it? How—oh, well, get facts and you won’t ask such questions!”

“Then it was done by an outsider?” blurted Delaney, staring through the wind-blown snow which came off the housetops. “It was done by the fellow who ’phoned and wrote that letter, or had the letter written? I don’t see how he could do it!”

Drew smiled at Delaney’s candor. “Neither do I,” he said simply. “But we’ve crossed Forty-second Street and we’re on the trail by everyday, up-to-date methods which never fail if they are continued long enough and men work hard enough. We’ll start with Harry Nichols—the man in olive-drab! I’ve his address!”

Delaney stepped behind his chief and followed in single file as the detective swung from the Avenue at Thirty-ninth Street and turned toward the east on the up-town side of the thoroughfare.

The snow had ceased falling from out the leaden sky. A roar came to them of the awakening city which was stirring in its last sleep. A tug whistled hoarsely somewhere on the East River. Its blare and signal echoed down the towering canyon. An answering rattle sounded from the Elevated. A milk wagon churned by. A deep-seagoing hansom-cab, of the vintage of ten years before, struggled along Madison Avenue as the two detectives paused on the corner and sought a pathway through the snow to the opposite side.

“Some night,” said the operative, pulling down his derby hat and facing Drew. “A hell of a night to be out. Good thing we walked, though. My head is clearing.”

“It needed clearing,” said the detective. “Some of your deductions were impossible. Whom do you suppose we’re going to meet here?”
