The Four Seasons Quest — Cecilia Peartree

Is Aunt Caroline's murder just an isolated incident or could it be part of a much larger web of crime and intrigue? The case spawns secrets of its own which threaten to separate Flora and Oliver almost as soon as they get engaged.
Flora's wartime past still hasn't quite let go of her, but in this novel it becomes clear that there are dark secrets in Oliver Quest's family too. The action in this mystery/thriller ranges over the length and breadth of Britain and all the seasons of the year.
‘The Four Seasons Quest' is a sequel to ‘The Lion and Unicorn Quest' and is set in 1952.
