In this skillful blending of historical narrative and personal memoir, Jack takes us on a gripping journey through the secret world of code-breaking during World War II. 

The author traces the links from Horsforth, a village on the outskirts of Leeds, onto the decks of the HMS Aubrietia, the Royal Navy corvette that the village sponsored in 1941. In the dangerous North Atlantic seas of World War II, where ‘wolfpacks’ of German submarines patrolled the waters, Aubrietia’s encounter with U-Boat, No U-110, helps to uncover the coded mysteries of the Enigma – which leads us to Bletchley Park and the astonishing work of British cryptanalysts, such as Alan Turing.

With close personal links to places and people involved, Jack shares his admiration for the dedicated code-breakers and engineers whose activities helped defeat Hitler’s military might and win the war for Britain. 

Jack confidently states, “There are few, if any, people living today, whose lives have been touched so directly by the events of this compelling wartime drama as my own”.
