The Hoisted Petard — Bob Garland

The Hoisted Petard is an "explosive" story of murder, corruption, sex, and a local political campaign. In his sixties, Humboldt Prior, now a university lecturer in information technology, is enmeshed in a decades-long series of crimes which he solves using his past experience as a secret intelligence agent and a corporate executive, while avoiding (or not avoiding) the blandishments of a very provocative younger woman.
