It’s been two years since Dinah Collins left the NYPD in disgrace, forced out for digging too deeply into the sudden disappearance of a fellow cop - her brother, Danny. Now, scraping by as a PI, Dinah is hired to find a young woman, Lucy Fisher, who vanished on Halloween, last seen wearing a creepy costume. As she pursues a deadly trail of clues, Dinah will find she’s faced with a terrible choice: If she can only save one person, Danny or Lucy, who will it be?

When eight-year-old Daisy Mason vanishes from her family’s Oxford home during a costume party, Detective Inspector Adam Fawley knows that nine times out of ten, the offender is someone close to home. And Daisy’s family is certainly strange—her mother is obsessed with keeping up appearances, while her father is cold and defensive under questioning. And then there’s Daisy’s little brother, so withdrawn and uncommunicative . . .

A bizarre chain of events begins when 16 unlikely people gather for the reading of Samuel W. Westing's will. And though no one knows why the eccentric, game-loving millionaire has chosen a virtual stranger - and a possible murderer - to inherit his vast fortune, one thing's for sure: Sam Westing may be dead...but that won't stop him from playing one last game!
