Another romp through the idea of computational demonology. It avoids the cliche of the spy novel by … making the notion of being a cliche into a plot device. As a homage to H.P. Lovecraft this entire series is hard to beat, full of knowing allusions handled deftly and with a touch of cyberpunk.

5/5. Finished Saturday 30 May, 2020.
