Does pretty much what it says on the tin! If you're looking for a '60s thriller containing a dastardly plot to blow up Gibraltar, a family (husband, wife, & her brother) of spies whose intelligence varies somewhat with the needs of the plot, and a climax containing the DIRE THREAT of being torn apart by Barbary apes(?!) -- and if you're willing to overlook an unfortunate amount of Hollywood Racist Caricature Arabs, which I found rather difficult to overlook at some points -- then this is the book for you. If it's not, you're probably not planning to pick up a book called The Secret Service Girl anyway.
