Two full WWII novels involving espionage and chases. In Death Beach, set in 1944, a Bletchley Park cipher clerk is used by the intelligence services due to being born in Hamburg to a German mother and English father. A series of lies and threats to his life sets him on a chase through England, the Irish Free State and the North Sea with information for the Germans. But the Allies who initiated this, realise he has information about the Slapton Sands disaster they don't want to Germans to have. They must try to stop him. In Death Bell, the German secret project to win the war has to be investigated and halted at any cost. The Bell was a real project and the race is for the Allies to capture it before the Russians arrive. This is a realistic explanation of a secret operation of which only a few flooded tunnels and strange concrete edifice remain in Poland, in a part then belonging to Germany. Lots of twists and turns in these espionage novels.
