In the following pages you will find some interesting experiences taken from the Professor’s case book. They illustrate forcibly his contention that crime is simple and that most criminals are caught, not by any superhuman qualities of the detective, but by their own ignorance, stupidity, or carelessness.

In these accounts every fact, every clue necessary to the solution is given. The answer is in the story itself. You need look nowhere else but there. Each problem has only one possible solution.

Written in less than two hundred and sixty words, these little stories can be read in a minute.

Here is your chance to work on an absolute equality with the Professor; to match your wits with his and the criminal’s. You know as much as the Professor does. Now you have an opportunity of proving just how good a detective you are and what poor detectives your friends are.

The author hopes you will find them as fascinating reading as they were in the telling by the Professor.
