When narrator Charles Copley's father dies, Charles--recently robbed of both job and wife--loses himself in reading the old man's WW II diary. He's surprised to learn that his mild and taciturn father was an Intelligence man who supplied Yugoslavia's Partisans with arms and money (5000 gold sovereigns). He's even more surprised when it turns out that, after 30 years, the diary is still hot stuff. Pro-Nazi Croatian extremists want to destroy it; an aged but unrepentant SS man wants to use it to track down that never-delivered load of gold, hidden somewhere in Montenegro. When the Nazi kills Charles' son (accidentally on purpose), Charles decides to go after the gold himself--to Forget Everything and also to lure the Nazi into a death-duel. This he does, accompanied by the half-Montenegrin daughter of a British Intelligencer who died in the war. Charles gets his man and his bloodied Miss Right, the British government gets the gold, and a rather familiar story outline gets a fresh, tight reworking from a British sci-fi and suspense writer little known here.
