Prelude to a Certain Midnight

In London under the fog of war, a 10-year-old Jewish girl is murdered. The police have no clues and little interest, so crusader Asta Thundesley takes up the challenge, sifting through clues and gathering up suspects for a dinner party where... nothing is learned. Detective Turpin goes by the book, and finds himself with a stunning set... of dead ends. Fascinating example of life's perils by author Kersh (Night and the City), who reminds for every winner, there can be a ton of losers. First published 1947.
