The Secret Hours is Like Gretchen Wiener's Hair: Full of Secrets

If you are a fan of Jackson Lamb and the show Slow Horses, then you need to read Mick Herron's standalone prequel The Secret Hours-- this book fills in a lot of the gaps and backstory of the misfit MI5 gang of Slough House and does it in brilliant fashion: the novel centers on a government inquiry into some wild and nasty business in Berlin just after the wall fell and the spies came out of the cold . . . and while it seems to be all codenames and obfuscation, if you're a fan you will start to recognize many of the characters and plot strands from the show . . . very entertaining and very illuminating but you certainly want to watch Slow Horses or read a few Slough House books before you dive into this one.
