This book is short and to the point. Quiller is a pen name for several authors including Kenneth Bulmer, which is why I read it. The book begins in the middle of the games with the main event being Vulpus fighting a Jew to the death. About to strike the killing blow, he recognizes his adversary. The next half of the book is devoted to Vulpus' recollection of how he met Samuel ben Ezra. The end of the book brings us back to reality and to the question of whether Vulpus will kill his friend or not. I thought the concept of the bulk of the story taking place within the main characters mind interesting and novel. Essentially the story takes place in a short amount of time, say an hour, perhaps less. While the story is not 'graphic' it is violent with minor sexuality. The sorts of things that you would expect from such a tale given the subject. I enjoyed it immensely and look forward to the other five in the series.
