This was a delight. I am a huge fan of this series but the novellas have been largely enjoyable without being, top tier, maybe. This certainly was top tier. It's 1920's New York during the Harlem Renaissance, into this Aaronovitch throws Nightingale (who has lived since about the turn of the century) and a bit of P G Wodehouse using a class mate of Nightingale. Stir, shake and get that hit from the bathtub gin cocktails. A definite recommend.
