This book, Don't know Jack, is the most convoluted series of events I've ever tried to put together. Otto and Gaspar are on a wild goose chase set about by a "boss" who is never named until the last couple of chapters. He has them going in circles, not explaining anything for them...and on a time schedule that would have had the healthiest, most physically fit person falling by the wayside; and they didn't even get jet lag. The timing was too unrealistic. And then supposedly the tall, giant of a man was glimpsed in the shadows at the very end. Indeed!!! Jack doesn't operate that way. Won't waste my time or money on another Capri book.
