This is the eagerly awaited third novel featuring Inspector Madden, from the author of "River of Darkness" and "The Blood-Dimmed Tide" ...he could see in the distance, to the south-east, searchlights probing the night sky, illuminating the barrage balloons that floated like giant moths above the darkened city. They were there to hinder the approach of flying bombs, though few believed they were of any use, any more than the ack-ack guns that blazed away furiously whenever the strange craft with their fiery tails appeared in the skies...And neither were they any defence at all against the V-2s, which descended without warning like thunderclaps and which Londoners had come to fear more than any other weapon used against them. During a blackout on the streets of London on a freezing evening in late 1944, a young Polish land girl, Rosa Nowak, is suddenly and brutally killed. For the police, their resources already stretched by the new war regulations and the thriving black market, this is a shocking and seemingly random crime. No one can find any reason why someone would want to murder an innocent refugee. For the former police inspector John Madden, the crime hits close to home. Rosa was working on his farm and he feels personally responsible for not protecting her. His old colleagues Angus Sinclair and Billy Styles are still at the Yard but struggle to make sense of their few clues. Their only lead points towards Europe - but as the war rages across the continent, will they find the killer before he strikes again?
