Mr Pottermack's Oversight - Hardcover

R. Austin Freeman is the doyen of the scientific division of detective writing, is best known for his character Dr John Thorndyke. A close and careful investigator and the outstanding medical authority in the field of detective fiction, R. Austin Freeman not only tested the wits of the reader but also inspired many modern detective forensic methods. Much of his long life was spent as a physician and surgeon at the Middlesex Hospital, London. He also held posts in West Africa and later was a medical officer at Holloway Prison. The most famous of the Edwardian detective writers, he rescued the detective story from "thrillerdom" and made it acceptable to a more discerning class of reader.

Good Mr. Pottermack commits the perfect murder, except for one teensy weensy little detail. He forgot Dr. Thorndyke might just take the case.
