The Tremor of Forgery
From crimereads.com: "American writer Howard Ingham arrives in a sweltering Tunisia in search of inspiration for a new movie script he has been commissioned to write. He falls in with an ex-pat cast of characters worthy of a Paul Bowles novel (though of course he largely favoured Morocco over Tunisia) – a right wing American propagandist, a gay Danish painter and the staff of his hotel. One night, Ingham finds someone breaking into his apartment. He throws his typewriter at the intruder, possibly killing him. The body is dragged away by the intruder’s accomplices. As well as a building novel of suspense The Tremor of Forgery is also a good example of the ‘ex-pat novel’ asking questions about the relative roles of ex-patriate and local in a given locale. If you need a recommendation, no lesser a figure than Graham Greene thought it Highsmith’s finest novel. "
