After A Man Lay Dead
The Moving Toyshop by Edmund Crispin
If you fell for the country-house whodunit elegance of A Man Lay Dead, you need Crispin's vanishing toyshop mystery—where every clue is a fair-play challenge, every character is delightfully absurd, and Gervase Fen brings the same suave detective brilliance as Inspector Alleyn but with twice the speed and literary mischief. Golden Age puzzles have never felt this alive.
