Death in Damascus: A Heathcliff Lennox Murder Mystery, Paperback

There's a damsel in distress and accusations of attempted murder flying around, but it's not in the comfortable confines of the English countryside, it's in the very distant city of Damascus. Lennox must go and investigate, although he's not too keen on exotic locations, and his old retainer, Greggs is distinctly averse to the very idea.
Nevertheless, ex-Chief Inspector Swift persuades them and they reach the ancient city to discover a movie crew, a spy and a couple of mysterious ladies. Nobody seems to be telling the truth, they all have secrets, and there's one secret in particular that's drawn them like bees to the honeypot. But what is it? And then there's murder, and mysteries from the ancient past, and a handsome Sheik who remains in the shadows.
Heathcliff Lennox and Swift must investigate and use all their ingenuity to unravel the enigma that lies hidden in the dusty streets of ancient Damascus.
Major Heathcliff Lennox, ex-WW1 war pilot, six feet 3 inches, unruly dark blond hair, age around 30 - named after the hero of Wuthering Heights by his romantically minded mother - much to his great annoyance. Death in Damascus is the fourth book in the Lennox series.
