Crime-scene photographers Sarah, Hugh, and Mick are summoned to the goriest crime scene they’ve ever encountered. A pub owner named Harry Warbrick has been found hanged. His murder becomes a sensation because he was England’s top hangman. Sir Gerald, owner of the Daily World, announces that they—meaning Sarah and her friends—will investigate and solve Warbrick’s murder before the police do. She and her friends discover a connection between Warbrick’s murder and the most notorious criminal he ever executed: Amelia Carlisle. Something happened at Amelia’s execution. The Official Secrets Act forbids the seven witnesses present to divulge any information about it. But Harry had a bad habit of leaking tips to the press. What is the secret, and who hanged the hangman?
