1941, and Detective Inspector Stefan Gillespie is ferrying documents between Dublin and war-torn London. When Ireland's greatest actor is arrested in Soho, after the brutal murder of a gay man, Stefan extricates him from an embarrassing situation. But suddenly he is looking at a series of murders, stretching across Britain and Ireland.

The deaths were never investigated deeply as dead queers are nobody's priority. And there are reasons to look away now. It's not only that the killer may be a British soldier, Scotland Yard is also hiding the truth about the victim.

But an identical murder in Malta makes investigation essential.

Malta, at the heart of the Mediterranean war, is under siege by German and Italian bombers. Rumours that a British soldier murdered a Maltese teenager can't go unchallenged without damaging loyalty to Britain. Now Britain will cooperate with Ireland to find the killer and Stefan is sent to Malta.

The British believe the killer is an Irishman; that's the result they want. And they'd like Stefan to give it to them. But in the dark streets of Valletta there are threats deadlier than German bombs...
