MAPP AND LUCIA is the centrepiece of E.F. Benson's series of Lucia novels - bringing together for the first time the eponymous middle-aged doyennes of polite 1930s society Miss Elizabeth Mapp and Emmeline Luca (Lucia to her friends).
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender, Thorne searches the bulletins for a reported death that matches the photograph. Then another picture arrives.
