Professor and amateur sleuth Henry Spearman uses economics to try to solve a murder while on a Caribbean vacation

Cinnamon Bay seems like the ideal Caribbean getaway. But for Harvard economist and amateur detective Henry Spearman it offers an unexpected and decidedly different diversion: murder. With the police at a loss, Spearman investigates on his own, following a rather different set of laws-those of economics. Theorizing and hypothesizing, Spearman sets himself on the killer's trail as it winds from the perfect beaches and manicured lawns of a resort to the bustling old port of Charlotte Amalie to the perilous hiking trails of a dense forest. Can Spearman crack the case using economics-and before it's too late?

"This is a tight little mystery that should hold the interest of any student who enjoys detective stories. At the same time, it contains some basic economic lessons, presented in a way that the first-year student will have no difficulty understanding. . . . Its style is crisp and entertaining, and its cast of characters will delight any mystery lover. . . . What gives Murder at the Margin its sparkle are the shrewd observations about academic life and the authors' ability to transform statements of economic law into deft character analysis."---Sarah Gallagher and George Dawson, Journal of Economic Education
