Steve Punt returns for a fourth series as Radio 4's very own gumshoe, re-opening a case of murder by poisoned partridge in 1931.

Steve embarks on a historical whodunit, examining the bizarre death in Deepcut, Surrey of an army lieutenant, Hubert Chevis, who died after eating a partridge laced with strychnine. 80 years on, the Chevis case remains unsolved and nobody was ever been charged with his murder.

To add to the mystery, Chevis' father received a sinister telegram which read "Hooray, hooray, hooray" and a follow-up postcard from the same unknown sender which stated "it is a mystery they will never solve".

Steve marshals the facts, reopens the coroner's file and locates a relative with important evidence to share. Was it the wife, her ex-husband, the batman or the cook?
