Is a mystery-woman named Sheila, suddenly on the scene in London, really just a pickpocket? Or is she a KGB spy? British Intelligence needs to know--so silly caper #7 for tall, blushing, inept British spy Appleton Porter begins when Apple is recruited to be a test pickpocketing victim. (His great height is an obstacle to picking; only a true pickpocket would succeed.) Soon, however, Apple is going beyond his assigned duties--falling in love with Sheila, pretending to be a pickpocket himself (to cozy up to her), and finding out that she is indeed a KGB agent: her mission is to find the pickpocket who picked the pocket of a recently deceased Soviet diplomat. . . and to recover whatever it was (a mystery-item) that was picked. Visits to assorted ""dips"" (including The Great Harold, a part-time magician) ensue; so does some rough stuff with Cubans, Israelis, and the CIA. And the outcome is even more inanely giddy than expected. One or two chuckles; mostly just mindless twiddling.
