Thus Was Adonis Murdered: The first of four mysteries by the late Sarah Caudwell will make you want to read the rest. A ludicrous murder mystery set in Venice is solved long distance by a pack of dry and droll English barristers in a somewhat Rumpolian vein -- delightfully lighthearted, more than a bit randy, and exquisitely written in a quasi-Edwardian style (despite its setting in the 1980s). Highly recommended if you need something trivial and fun, yet clever and sharp.
Let me describe it another way, I picture this book being read by elegant women in beachside cabanas who grin slyly at the more witty passages. And yet I enjoyed it to pieces.
(That doesn't make me gay, does it? Um, no, it doesn't.)
