The case of Maybrick, Seddon and Armstrong are described, as well as lesser-known accounts such as that of Reverend Clarence Richeson who poisoned his young mistress with a cyanide capsule after convincing her it was an abortant. Sections review aspects of poison crimes, legal issues, forensic tests, autopsy, exhumation, pioneer toxicologists and the characteristics of poisoners.
