Ernest Lohmann, the honorable ex-Berlin Police Inspector who escaped to England one step ahead of the Gestapo (Death's Head Berlin and Death Squad London), is now asked by Whitehall to "babysit" Capt. Robert Pardoe while he's on a secret mission in America--and, if possible, to keep him from killing prostitutes: he's their main suspect in cases in Singapore, London, and Washington. Lohmann adds two more possibilities--Pardoe's tormented (inexplicable blackouts) only friend, a homosexual FBI agent; and a British Embassy security officer stationed in D.C. With the aid of a beautiful Embassy secretary, Lohmann survives encounters with Hoover, the FBI, even Nazi assassins, but the bodies pile up, including one crucial to Pardoe's hush-hush work. By removing Lohmann from the active war zones of prior books to isolationist America, Gerson diminishes the tension, settling instead for facile potshots at easy targets (Hoover, the FBI, etc.).
