Showing Dark Summer in Bordeaux by Allan Massie

With his son's safe return, Superintendent Lannes and his wife can, at last, have some joy amid the grim reality of Vichy France. Not that the unexplained murders seem to have stopped. Allan Massie's second volume in his trilogy continues the story of dogged detection in a world seemingly gone mad. His first volume, Death in Bordeaux, was reprinted three times and garlanded with praise by reviewers.
