Although it was first published in 1947, Gilbert began this novel in the years immediately before World War II and didn't finish it until he returned from active duty. Set behind the walls of the residential Close of Melchester Cathedral, it's a classic British mystery in which a young Scotland Yard detective is asked to interrupt his holiday to find out if the accidental death of Canon Whyte was indeed an accident.

This novel followed Close Quarters, and once again features Inspector Hazlerigg. It is a gangster suspense thriller about the postwar black market. There is robbery, murder, and smuggling in a volume that contains all of the ingredients of a first-class tale, with Gilbert’s particular trademarks of dry humor and wit, and an obvious knowledge of the subject written about with fascinating and revealing detail and description.

Life had been good for Paddy Yeatman-Carter. First-class Rugby and good beer at eightpence a pint before the war; during the war, command of the finest regiment in the British Army. But peace-time life as a clerk was more than a bit dim—until he saw an attempted suicide and decided to intervene. That act of good nature cost him his job and plunged him into the deepest intrigues of the City, where he and his friends walked in the shadow of death.

Mystery crime fiction written in the Golden Age of Murder Horniman, Birley and Craine is a highly respected legal firm with clients drawn from the highest in the land.

The partners and staff of the firm keep a watchful and suspicious eye on their colleagues, as Inspector Hazlerigg sets out to solve the mystery of who Mr. Smallbone was—and why he had to die. Written with style, pace, and wit, this is a masterpiece by one of the finest writers of traditional British crime novels since the Second World War.

One final opportunity remains: the defendant calls on solicitor Nap Rumbold to replace the defence counsel,and grants an eight-day reprieve from the proceedings. Without any time to spare, Rumbold boards a ferry across the Channel, tracing the roots of the brutal murder back into the war-torn past. Expertly combining authentic courtroom drama at the Old Bailey with a perilous quest for evidence across France, Death Has Deep Roots is an unorthodox marvel of the mystery genre.
