In Pursuit of the Proper Sinner

A theatrical producer shoots himself on the night of his greatest triumph. A young woman camping on the Derbyshire moors is bludgeoned to death. A motorcyclist is found stabbed to death in the center of an ancient henge. Is there a connection? Detective Inspector Thomas Lynley is on the case, but recently demoted Constable Barbara Havers isn't about to let him go it alone.
