Frost At Christmas. (DI Jack Frost Book 1), Paperback/R. D. Wingfield

Fresh to provincial Denton in an oversmart suit, Detective Constable Clive Barnard is an easy target for Frost's withering satire. Assisted and annoyed by Barnard, Frost, complete with a store of tasteless anecdotes to fit every occasion, proceeds with the investigation in typically unorthodox style.
