Summer, 1936. The writer, Josephine Tey, joins her friends in the holiday village of Portmeirion to celebrate her fortieth birthday. Alfred Hitchcock and his wife, Alma Reville, are there to sign a deal to film Josephine's novel, A Shilling for Candles, and Hitchcock has one or two tricks up his sleeve to keep the holiday party entertained - and expose their deepest fears.But things get out of hand when one of Hollywood's leading actresses is brutally slashed to death in a cemetery near the village. The following day, as fear and suspicion take over in a setting where nothing - and no one - is quite what it seems, Chief Inspector Archie Penrose becomes increasingly unsatisfied with the way the investigation is ultimately resolved. Several years later, another horrific murder, again linked to a Hitchcock movie, drives Penrose back to the scene of the original crime to uncover the shocking truth.
