Publisher's Synopsis
A man is found dead in an escape tunnel in an Italian prisoner-of-war camp. Did he die in an accidental collapse or was this murder? Captain Henry Cuckoo Goyles, master tunneller and amateur detective, takes up the case. This classic locked-room mystery with a closed circle of suspects is woven together with a thrilling story of escape from the camp, as the Second World War nears its endgame and the British prisoners prepare to flee into the Italian countryside.
