"The Moving Toyshop," published in 1946, was Crispin's third Gervase Fen mystery. This particular whodunit involves an unusual will, a hunt for five eccentric characters named after the nonsense poems of Edward Lear, and of course, a moving toy shop with a corpse in its upper story. The action begins in the Autumn of 1938, when the poet, Richard Cadogan wangles an advance from his London publisher and sets out for a vacation in Oxford.
