Footsteps in the Dark -- Georgette Heyer
I need a brainless-but-well-written mystery occasionally. This was perfect. Written in 1932, the dialogue included loads of words & phrases like: "jolly", "cracking good", "right ho" and "what what". It was kind of like Enid Blyton, except... entertaining. And funny.
I did have the murderer pegged LITERALLY the first time he appeared, but that didn't detract from my enjoyment at all. How could it, when there were bits like this?
"Its robe was black, and so were its hands--at least the one that pointed at me was. I daresay I am stupid, but that seemed to make it more unnerving, for I have never liked coloured people, and a coloured ghost I find very upsetting."
"For goodness sake let me sit down; I feel like a piece of chewed string."
"Don't you worry, sir!" Mrs. Bowers said, picking up the poker. "I just wish that Monk would come in, that's all! I'd Monk him!"
He bent and kissed Celia's pale lips. "Keep your pecker up, old lady."
Georgette Heyer is mostly known for her romances, which I have pretty much zero interest in, but I'll definitely be watching for her other mysteries.
