Harvard professor Henry Spearman―an ingenious amateur sleuth who uses economics to size up every situation―is sent by an American entrepreneur to Cambridge, England. Spearman's mission is to scout out for purchase the most famous house in economic Balliol Croft, the former dwelling place of Professor Alfred Marshall, John Maynard Keynes’s teacher and the font of modern economic theory. A near miss for the American entrepreneur and the shocking and bizarre murder of Nigel Hart, the master of Bishop’s College, soon make it clear that the whole affair is risky business. When a second corpse turns up, Spearman is jolted into realizing that his own life is in peril as he finds himself face to face with the most diabolical killer in his experience.

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?
Economics professor and amateur detective Henry Spearman tackles a mystery where the price of art is murder In The Mystery of the Invisible Hand, Henry Spearman, an economics professor with a knack for solving crimes, is pulled into a case that mixes campus intrigue, stolen art, and murder. Arriving at San Antonio’s Monte Vista University to teach a course on art and economics, he is confronted with a puzzling art theft and the suspicious suicide of the school’s artist-in-residence. From Texas to New York, Spearman traces the connections between economics and the art world, finding his clues in monopolies, auction theory, and Adam Smith. How is a company’s capital like an art museum’s collection? What does the market say about art’s authenticity versus its availability? What is the mysterious “death effect”—and does it lie at the heart of the case? Spearman must rely on his savviest economic thinking to answer these questions—and pin down a killer.
Cinnamon Bay Plantation on lush, tropical St. John was the ideal Caribbean island getaway: Or so it seemed. But for distinguished Harvard economist Henry Spearman, long overdue for R & R, it offered diversion of a decidedly different sort and one he'd hardly anticipated: murder.It couldn't have happened to a nicer guy. Prickly and priggish, Gen. Hudson T. Decker (Ret.) might have been a Cinnamon Bay regular, but he'd managed to alienate fellow guests and a lot of townspeople over the years. Suddenly, before the local inspector has assembled a suspect list, there is a mysterious drowning and a second murder, this time a former U.S. Supreme Court justice. Prime suspects abound: a liberal professor of divinity, a vengeful wife, an alleged girlfriend, and a handful of angry local activists.While the island police force is mired in an investigation that leads everywhere and nowhere, the diminutive, balding Spearman, who likes nothing better than to train his curiosity on human behavior, conducts an investigation of his own, one governed by rather different laws--those of economics. Theorizing, hypothesizing, Spearman sets himself on the trail of the killer as it twists from the postcard-perfect beaches and manicured lawns of a premier resort to the bustling old port of Charlotte Amalie to the densely forested hiking trails with their perilous drops to a barren, deserted cay offshore.Now available in a new critical edition, Marshall Jevons's Murder at the Margin was first published in 1978, when it marked the debut of Henry Spearman. Spearman relies on economic thinking to solve crimes--a distinction that places him in the pantheon of such fictional investigators as Father Brown, Miss Marple, Hercule Poirot, and Rabbi Small.
