100 Mysteries for Arm-Chair Detectives
by J. C. Cannell

Based on actual crimes and mysteries investigated at Scotland Yard.

This is a fun read if you like short problems of deduction and observation. While most of them are not locked room problems, there are two of them in this collection, #34 and #88. One of them states that on an express train, a girl was found dead in a third-class compartment. Her head was badly injured. A violent blow had caused her death. The train had not stopped during the journey and the girl had occupied the compartment alone all the way.

Magicians will be able to solve some of the mysteries more easily because they rely on knowledge a well-read magician will likely know. Will Goldston, mediums, and fakirs make appearances.
