Now or Never [EPUB ebook] 

Tommy is back, and again he’s in Germany, posing as a camera-toting tourist while trailing Fascists. The investigation starts in Cologne when a corpse is found hung out like a batch of wash from a ruined building. Then Tommy learns about two girls whose custom it is "to frolic among the ruins" late at night and finds that his buddies are on hand to help him unravel the mystery of the Silver Ghosts, the Nazi outfit he is after. After another man has died among the wrecked buildings, can Tommy and his cohorts blow the top off an intrigue that might turn all Europe topsy turvy?
