The Uninvited

Hesketh Lock works for Phipps and Wexman, a company that employs the best investigative brains in the world. By using Venn diagrams he specialises in identifying common threads in the unexplained; in this case a chain of shocking events from Harrogate to Taipei via Stockholm. He is called in to look into a string of random sabotage incidents often followed by the suicide of the perpetrators.
