Murder, Majorcan Style

An Inspector Alvarez Mystery
Inspector Alvarez is just considering whether he can surreptitiously leave work early when a colleague calls to tell him that an Englishman has been found dead in his car in his garage, the engine on and the tank empty.
Alvarez, chafing over the prospect of an evening on the job, proceeds to the scene, but his hopes of a quick and easy case are dashed - for while the man was found in a car full of fumes, it appears the cause of death was not carbon-monoxide poisoning . . .
