The Janus Affair, by Pip Ballantine and Tee Morris, is the second novel in the Ministry of Peculiar Occurrences Series. It follows the eponymous Ministry, which is a “League of Extraordinary Gentlemen and Women” style Imperial British governmental agency. More specifically, we’re concerned with the continuing exploits of Wellington Books, the Ministry’s very English head archivist, and Eliza Braun, New Zealander and still-stewing-about-being-demoted ex-field agent (now archiving assistant). Books and Braun discover that women connected with the suffragist movement have been disappearing in very mysterious circumstances, and that the Ministry has been burying the cases. Despite explicit instructions to stay out of it, their shared sense of duty and Braun’s personal connection to the movement draw them into a dangerous, high-stakes investigation. The Janus Affair has fun techy bits, a sense of liveliness, and many relatively appealing characters.
