It is the Whitsun weekend of 1931 in the once-fashionable resort of Frencham-on-Sea. A housewarming party at Seaview One, the thoroughly modern home of Sir James and Lady Theodora Phillips, goes horribly wrong when Lady Theodora is found drowned in the swimming pool.
Suspicion falls immediately on one of the servants, but the police are unable to make the charge stick. Two of the house guests, Clarice Thompson and Cliff Thorley, begin to notice the undercurrents of tension and rivalry among the guests, and that one person in particular is acting very suspiciously - suspiciously enough to warrant further investigation.
Little do they realise, however, that their attempts at amateur detection are leading them into deadly waters - quite literally.
This is the second Clarice and Cliff 1930s Golden Age style crime novel by the author of the popular Reverend Shaw series.
