Wensley provides a detailed account of his time working on some of the most high-profile cases of the day, including the Jack the Ripper murders, the theft of the Irish Crown Jewels, and the Sidney Street Siege. He also discusses the challenges and successes of policing in London during the early 20th century, including the use of new technologies such as fingerprinting and forensic science.
