has a big office in a down-town skyscraper. He is what the A. P. L. calls a "suspect." Let us call him Biedermacher.
About midnight or later, after all the tenants have gone home, you and I, who chance to be lieutenants and operatives in the League, just chance in at the corridor of that building as we pass. We just chance to find there the agent of the building—who just chances also to wear the concealed badge of the A. P. L.

"Good night, John," he yawns to the janitor, when they meet him on the floor below. "Pretty late, isn't it?"
The three men pass out to the street and go home. Each of them in joining the League has sworn to break
