The Craig Poisoning Mystery, first published in 1930, is a classic British ''golden-age'' murder mystery. The book, authored by A. E. Fielding (whose real identity remains itself somewhat of a mystery), features Scotland Yard''s Chief Inspector Pointer, who is called to a country estate after the owner is found dead due to chronic arsenic poisoning. From the dustjacket: The case arising out of the death of Ronald Craig was one of the most perplexing that Chief Inspector Pointer ever had to solve. No clue, recognized as such, was left behind either as to the motive for the crime, the criminal, or the way in which the crime was carried out. Pointer has to hunt for each in turn. Though the circle is narrowed down to a handful of the dead man''s intimates, yet it turns and re-turns in a very baffling manner.
