In the twenty years he has lived in Bangkok, Christopher G. Moore has written nine novels starring Vincent Calvino, a disbarred American lawyer working as a PI in the steamy Thai capital. Internationally acclaimed, the prize-winning novels have been translated into ten languages but were first published in North America beginning with the hardcover edition of The Risk of Infidelity Index, the latest book in the series. When Calvino's surveillance of a major drug piracy ring ends in definitive video evidence, it looks like his fortunes are about to turn. The money from the job will be enough to buy out the massage parlor downstairs and restore some dignity to his place of employment. But when the client dies of a heart attack, and Calvino finds the body of a murdered massage girl downstairs, the authorities get suspicious of the farang in the wrong place at the wrong time, twice. To make matters worse, with the dead man unlikely to pay, Calvino is desperate, forced to take on a job he doesn't want. The clients are three expat housewives who want Calvino to trail their husbands. They have been rattled by The Risk of Infidelity Index, a handbook that ranks Bangkok as the city where men are most likely to stray, and are haunted by the idea of their men in the bars on Patpong and Soi Cowboy. Unfortunately for Calvino, jealous wives tend to be unhappy, regardless of the results, and drug pirates aren't the type to play nice.
