Book Review: Death of a Scriptwriter by M. C. Beaton (1998)
Synopsis: At one point in her life, Patricia Martyn-Broyd was a moderately successful novelist. Now in her seventies, her books are no longer in print, her agent is deceased and she is largely forgotten with her only (reluctant) friend being Constable Hamish Macbeth. When a TV producer wants to turn one of her murder mysteries into a show, she is thrilled. However, her elation soon turns to despair when she learns the show's scriptwriter wants to turn her conservative novel into something racy. As a result, when the scriptwriter and, later, the show's leading actress, are murdered, she becomes the favorite suspect and it is up to Hamish to find out the truth.
