When owners of a struggling detective agency are found asphyxiated in their car, Detective Chief Inspector Lloyd rejects the majority opinion that they committed suicide. And his theory - that they were murdered, becomes even likely when the doomed couple's one client, wealthy Mrs. Angela Esterbrook, is found shot to death. Why would someone with her sort of money employ an untried agency to carry out an investigation? The superrich Esterbrook family is a puzzle that Lloyd and his partner, Judy Hill, most solve before it's too late. For the curtain is rising on a tragedy of Shakespearean grandeur. But no one, not even the cunning killer, anticipates how the plot will take on a lethal life of its own - beyond everyone's control.
