Risk of Infidelity Index by Christopher G. Moore (2007, Hardcover

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, and were first published in North America in 2007, with The Risk of Infidelity Index, the latest in the series. When Calvino’s surveillance of a drug piracy ring ends in definitive video evidence, it looks like his fortunes are about to turn. But when Calvino’s client dies of a heart attack, and he 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 forced to take on a job he doesn’t want, trailing the spouses of three expat housewives who have been rattled by “The Risk of Infidelity Index,” a handbook that ranks Bangkok as the city where men are most likely to stray. Unfortunately for Calvino, jealous wives tend to be unhappy, regardless of the results, and drug pirates aren’t the type to play nice.
