The Dovebury Murders

It begins with a seemingly insignificant robbery at a local printing company, but things really start to happen when Inspector Waghorn is sent to aid the local police in the investigation of the murder of a small-time local troublemaker, poisoned in the home of a parsimonious and rather secretive local man by wine tainted with Oxalic acid. The local force, having traced the history of the fatal drink, are quick to suspect the host, though the motive seems somewhat lacking. Waghorn is not so sure, but is unable to offer a better alternative solution. However, the case appears to be at an end when the chief suspect dies in what the police are satisfied is an accident.
