David Tennant (Doctor Who, Broadchurch) delivers “a breathtaking and career-defining performance” (Daily Mail) as one of the most infamous serial killers in British history: Dennis Nilsen. Known as the “kindly killer”, Nilsen was an unassuming civil servant who spent five years murdering young men he met on the streets of Soho. When he was finally caught in 1983, Nilsen had murdered a total of fifteen men, making him Britain’s most prolific serial killer of the time.
