Who Killed Santa Claus?

Barbara Love is a famous TV star who, just before her Christmas party, is threatened by a chilling voice on her answering machine and then receives a macabre present boxed in a miniature coffin.

Not so much a 'whodunnit' but more a 'who's going to do it', as along troop the staff of her television show for the Christmas buffet, each one of them with a motive to murder her.
