A Deadly Episode Summary: A Film Set, a Cold Case, and a Confession
Spoiler warning: This section reveals the full plot, including the ending.
In A Deadly Episode, Anthony Horowitz is approached by independent producer Teresa de León to option his novel The Word is Murder.
His agent, Hilda Starke, negotiates a profit-sharing deal that also makes Daniel Hawthorne a police procedure consultant on the film.
At the first production meeting, screenwriter Shanika Harris wants to reshape the story. Director Cy Truman has only one prior success. The casting pairs arrogant star David Caine as Hawthorne with Ralph Seymour, a once-celebrated actor whose career collapsed.
Shooting begins in Hastings. Horowitz visits the set and overhears Caine insulting the script, the director, and Ralph through a live microphone. The production is already short on cash. A young runner, Izzy Mays, is fired after Caine complains about a photograph taken at a local pub.
David Caine is found stabbed in the neck inside his trailer.
Izzy Mays screams that “Hawthorne” has been killed. DSI Sarah Milnes and DC Joe Fuller bring Hawthorne and Horowitz in as consultants.
The murder happened at 2:04 PM. Caine’s fired agent, James Aubrey, was seen running from the trailer and tried to hide his blood-stained Prada trainers. Aubrey is innocent of the killing, but his panic came from finding the body.
Interviews reveal Caine’s toxic history. He slept with Cy Truman to learn BAFTA voting results. When he lost to Ralph Seymour, he filled a Nurofen capsule with ground peanuts and gave it to Ralph, knowing about Ralph’s severe allergy. Ralph vomited on stage and his career ended.
Hawthorne then connects the case to a 2010 disappearance at Foss Hall in Yorkshire. Estate manager Duncan McClintock was murdered, and chauffeur Harry Morgan confessed before hanging himself in prison.
At Foss Hall, Hawthorne and Horowitz learn that Harry Morgan was innocent. His autistic daughter, Jenny Morgan, killed McClintock after he shot her dog. Harry planted evidence to protect her.
The final link appears when Hawthorne realizes Harry Morgan missed a final prison visit because a 2012 environmental protest by Caine’s group, Last Gasp, blocked the M62. Harry’s widow, Deborah Morgan, blamed Caine for the delay that led to her husband’s suicide.
Deborah saw a photo of Caine eating steak and flying in private jets.
She concluded he was a hypocrite. She took a Syokami steak knife from her pub, The Battle, and stabbed him to death.
Deborah confesses and is arrested. On the train home, Horowitz discovers Hawthorne has been hacking his iPad and reading his draft notes.
