Murder in the Dark a Phryne Fisher Mystery

I normally like the Phryne Fisher Mysteries, but this one was one of Greenwood's lesser works. So forgettable indeed that I put it on my to-read list again, because I forgot I already had read it. Imagine my surprise when I started reading and this book seemed familiar. Uncanny.
Phryne is at a party of some decadent cultists she knew in Paris. The party is grand and the whole book seems more focussed to show off how awesome the party is, and forgets about the mystery for large parts of the novel.
The book kind of trickles along until it comes to a conclusion that can be seen as an end.
At least it wasn't "Blood and Circuses".
