A maniacal serial killer known as Queer Jack stalks London during the dark days of the Blitz, engaging the pursuit not only of Scotland Yard but of a highly placed German spy known as The Doctor. That's the premise behind Hyde's densely atomospheric new thriller, his latest after Hard Target (1990). Detective Inspector Morris Black, widowed, brilliant, introspective and Jewish, is "seconded" to MI5 for the duration of the murder investigation. Black's diggings must remain top-secret, because the killer always commits his grisly crimes in locations that are immediately bombed by the Germans. While Black deducts from the evidence and reviews his own haunted past, London turns to smoking ash around him. Meanwhile, a host of additional characters impedes his progress, most notably Katherine Copeland, a volatile American journalist-cum-spy whose assignment is to seduce Black and who ends up getting in the way at the most extraordinary moments. Hyde's scrupulous research and deep knowledge of the political realities surrounding the Blitz make his story utterly convincing, though at times the generous detail grows so thick that it chokes the narrative like a kudzu vine. The procedural elements are perfect, however, with scenes of ghastly carnage rendered so crisply that one can almost smell the fear and death. The final pages, in which Black, The Doctor and the forces of MI5 inevitably converge upon Jack, contain images of gore and tormented madness that can't soon be forgotten. Readers who relish the raw truth of human, and inhuman, history will find here what they are looking for.
This was an extremely exciting and interesting murder mystery, set in London during the blitz, with the main character Detective Morris Black trying to conduct his investigation with the bombs literally falling around him. And the story also includes some very interesting history of that time, including how close English sympathizers in the government and with close ties to the government came to making a secret deal with Hitler to pretty much turn the country over to the enemy!
But one thing I did have against the story was its ending, which was more than a little disappointing. Bit of a spoiler here: but I always like a happy ending and this book doesn't really have one. However, despite the ending, overall I really enjoyed reading this taut and engaging mystery.
