A Case of Possession follows up on The Magpie Lord fairly closely; Stephen Day and Lord Crane have returned to London, but not quite to their previous lives, setting up as many clandestine meetings as they can (perhaps not as secretly as they should). Rackham, the man who introduced them in the first place, wants a lot of money fast, and of course, they can be blackmailed. Stephen’s in a spot of trouble too, with even his nearest and dearest fearing his newfound power is a sign he’s gone to the bad.
Also, people are being found mauled by giant rats, and shamans from Shanghai are involved, bringing Lucien into Stephen’s world as a translator, putting him right at the centre of everything again.
I do enjoy these characters so much, and the fact that they can be relatively happy and open despite the homophobic setting; Lucien has no shame due to his time in Shanghai, and Stephen is reasonably sure he can handle any issues that arise, so Charles can tread lightly around the wretchedness that I’m sure many in the period faced. It’s not wholly forgotten, of course, but it isn’t a huge barrier between them. There are some adorable bits in this book as they figure things out and put their relationship on a firmer footing.
It’s also fun to see the new characters, including an excellent scene with some of Stephen’s closest friends, and some more glimpses of Lucien’s past. Some excellent quips and comebacks, too, which I shan’t quote in order to let anyone who wants to find them for themselves.
The mystery of the giant rats is also a nice nod to Sherlock Holmes, and it works together to create a very good excuse for Lucien to be part of it again — there’s no perfectly coincidental constant stumbling over bodies. (Okay, I know the Daisy Dalrymple books are very different in many ways, but it does grate that a whole series is hinged on Daisy finding murder everywhere she goes, and it’s becoming a slight pet peeve.)
Finally, there are several sex scenes in this book; none of them are plot-necessary, but they do advance the characters and show their states of mind, so that’s worth knowing.
It all comes together well, and as a bonus there’s a short story featuring a little more about Merrick.
