This book was a lot of fun to read. His writing style is so interesting to me. Since he's old-style British, he uses words, phrases, and dialogue which I find very original and creative. I'm sure this comes naturally to him--but it's new to me. As with his other books, we get to crawl inside the killer's head and think and see life as he sees it. Once again, I found myself sypathetic towards the killer--Jack Orchard. Campbell makes this easy by giving Jack a not-so-sinister motive for killing--he feels his luck has gone bad because he believes some of the 13 people who originally received his chain letter refused to pass it along. And how could anyone hate a killer who uses a blowlamp to subdue his victims? It's comical at times and adds to the humorous dialogue which comes about from Jack phoning his victims. There's a few dead spots in the book and the extensive scenery descriptions when Jack is driving around town is a bit much. Other than that, I feel this book deserves 5 stars for it's creativity, outstanding dialogue, interesting storyline, and pleasant humor. This is the fourth Campbell book I've read and plan to read more.
