Gervase Fen, the hero, is on first encountering him, an apparently simple character - a gentleman private detective in the mould of Albert Campion, although more intellectual than aristocratic.
As the character develops one can discern a more complex character, with hints of the genteel fashion of Miss Marple, tempered by the more prosaic nature brought about by exposure to human frailties. Being from an academic centre, one is drawn to the comparison of Fen with Morse, but this does not really exist, since Morse is more obviously romantic in his soul and yet more professional through his official position.
The book explores a familiar scene - the idyll of country life facing upheaval, but with the added twist of a backdrop of a by-election, which provides a sort of stabilising sub-text. Red herrings are not particularly in evidence, although all aspects of the book are relatively understated. The whodunnit element is not particularly taxing, but one tends to forget that and concentrate more on the quality of the writing.
A great book to relax with for crime acolytes with a penchant for the rather older English detective story.
