The Moving Toyshop (1946) is a work of detective fiction by Edmund Crispin, featuring his recurrent sleuth, Gervase Fen, an Oxford professor of English Language and Literature.

Famous poet Richard Cadogan takes an impromptu holiday to Oxford, where he studied at the university, after growing bored with the literary life in the suburbs.

He wakes up the next morning in a supply closet, but after escaping and bringing back the police, the toyshop is no longer there, replaced, it seems, with a grocer's.

Bewildered, Cadogan turns to an old friend at the University of Oxford, eccentric professor and amateur sleuth Gervase Fen, to help him solve the mystery of the moving toyshop.

The title comes from Pope's The Rape of the Lock:[1]With varying vanities, from every part, They shift the moving toyshop of their heart The novel is dedicated to the poet Philip Larkin, Crispin's contemporary at St John's College, Oxford.
