Philo Gubb, Correspondence-School Detective

Walking close along the wall, to avoid the creaking floor boards, Philo Gubb, paper-hanger and student of the Rising Sun Detective Agency's Correspondence School of Detecting, tiptoed to the door of the bedroom he shared with the mysterious Mr. Critz. In appearance Mr. Gubb was tall and gaunt, reminding one of a modern Don Quixote or a human flamingo; by nature Mr. Gubb was the gentlest and most simple-minded of men.

Now, bending his long, angular body almost double, he placed his eye to a crack in the door panel and stared into the room.

Within, just out of the limited area of Mr. Gubb's vision, Roscoe Critz paused in his work and listened carefully.

He heard the sharp whistle of Mr. Gubb's breath as it cut against the sharp edge of the crack in the panel, and he knew he was being spied upon.

He placed his chubby hands on his knees and smiled at the door, while a red flush of triumph spread over his face.
