False Value, by Ben Aaronovitch

Second paragraph of third chapter:

His ID badge gave his name as Stephen Higgins, in black on a pink background, and his department as Magrathea – models, maquettes and concept art. He turned smoothly, shifting his balance and letting his hands fall to his sides in a deceptively relaxed manner. I remembered how fast he’d been back at the London Library and matched his pose.

As with Feet of Clay, I had been wondering if I would continue my project of reading through the Rivers of London books, though I was more inclined to keep going in this case as I have only two more to go after this. And as with Feet of Clay, reading False Value reassured me that I should follow through and finish the series. Here we have Peter Grant, cohabiting with Beverly, a very pregnant river goddess, and going undercover to investigate a software company which appears to be concealing occult secrets from the age of Babbage and Lovelace. I think I like these books more when they take the narrator away from standard Met occult policing into new territory, and this surely did while at the same time remaining firmly rooted in London. The Douglas Adams theme of the software company is excruciatingly awful and also all too believable. All good stuff. You can get False Value here.

Next (and so far, second last) on this list is Amongst Our Weapons.
