I enjoyed seeing Campion late in his career. He is world-weary in this book, happy to leave the actual investigating to younger associates. The end brings a surprising twist, and finally reveals to the reader the meaning of the title. As with other Campion books this one relies heavily on space and time- who was where when. Also like other books in the series this can get overwhelming. Still, it's interesting to see the gentleman sleuth in old age, and the books makes for a satisfying mystery.
