Black Out, by John Lawton
This story starts off appearing to be a fairly hum-drum detective story, set in London shortly before the Normandy landings. As an example of its genre I thought it was pretty decent, but only pretty decent. But it soon got better, adding twists and turns as we learn that Our Hero isn't just up against a murderer. He's up against the Abwehr - no, an anti-Communist group in the OSS - no, a rogue OSS agent! These twists add spice. Unfortunately, the conspiracy-within-a-conspiracy gets a bit confusing, both for the reader and, I fear, for the author, and it falters terribly before a rather unsatisfying wrapping up of loose ends.
As is unfortunately all too common for Kindle editions, there is some poor type-setting, as for the occasional accented character - in, for example, words like "voilà" - the wrong character encoding has been used. In this case, it comes out as "voil√✝".
Overall, despite its ending (which, it seems, is universally the hardest thing for authors to write, perhaps because real world stories don't have an end), I enjoyed this book and recommend it.
