Entertaining and quick reads, these are the perfect thrillers for a summer or vacation. The 1979 release, which was a sequel to a 1965 book, managed to maintain the charm of the character despite the passage of time. In fact, the character seemed to be just as likeable as ever. What's more, this sequel is less dated than the first one. It takes the reader behind the curtains of the racing and betting industry in England, offering a fascinating glimpse into a world that would be quite interesting even to a non-horsey person. Sid Halley is one of the two series written by Dick and later continued by Felix. Their novels were adapted into a six-episode television series.
