I decided to do a little mini-exploration of vintage mysteries set in London, to go along with my read of Murder in Piccadilly! I snagged this one, & also bought the "Capital Crimes" BLCC anthology edited by Martin Edwards.
I already own Lord Edgware Dies, which takes place in London, so I'm going to give that one a reread as well, and possibly Margery Allingham's The Tiger in the Smoke, also mentioned by Edwards in the chapter on murders set in London, to round out the group.
In the middle of this, I'll also still be joining in the buddy read for Murder of a Lady late this week! Can't wait!
