Editorial Reviews

London's master sleuth, Sherlock Holmes, and his trusty sidekick, Dr. Watson, live again, thwarting criminals and con men with the aid of statistics and game theory in amusing short stories penned by physicist Bruce.
This is a highly readable and engaging introduction to many aspects of probability, logic and statistics. Bruce focuses his stories, set in turn-of-the-century London with Sherlock Holmes and Dr. Watson as the main characters, on aspects of mathematics where common sense frequently leads people astray. For example, the first story presents the cab drivers' fallacy, in which cab drivers set themselves a daily revenue target and work until they achieve it, then knock off for the rest of the day. This results in working longer hours on slow days and fewer hours on busy days. In fact, it is a wiser strategy to work longer hours on busy days, when customers are plentiful, and quit early on slow, unproductive days. The first chapter may puzzle readers not familiar with the Sherlock Holmes stories, as the time frame is not completely obvious, but Bruce makes it clear in the second chapter that these stories all take place around 1900. Several historical figures make interesting guest appearances (e.g., Charles Dodgson, aka Lewis Carroll). There are no equations in the book, as it was meant to be read through and not used as a textbook, but there is a bibliography for those wanting to delve more deeply into specific subjects. All in all, the book is a good read and is useful to mathematics teachers looking for ways to interest and motivate their students in specific topics in probability, logic, and statistics.
