The Case of Jennie Brice (Unabridged‪)‬

Allegheny, Pennsylvania, now a part of the city of Pittsburgh, floods frequently and Mrs. Pittman has her boat tied to the stair banister, just inside the front door. It's 1904 and Jennie Brice, a stage actress, is missing from Mrs. Pittman's respectable boarding house. 

A blood-stained rope, bloody towel, floating slipper, a soaking wet fur coat, and a missing onyx clock are all clues. Most helpful is the installation of a periscope from Mr. Holcombe's floor through to ceiling of the room below. Where is Jennie Brice?
