Wells and Wong return, spending hols in Daisy's family mansion, with a birthday party planned and guests arriving and storms brewing and floods flooding, you've got yourself a classic stately mansion whodunnit. One guest in particular seems to have nefarious designs and inspires enough suspicion and ill-will that when he falls foul of poisoning, the list of potential culprits includes most of Daisy's immediate family. Daisy, with heady obliviousness, ploughs ahead with her investigation while Hazel worries about the rather dark and grown-up secrets and situations that appear to be arising. That's been the hallmark of the series so far - dashing jolly-good schoolgirl detectives running down the darker corridors British life in the 1930s as delineated by the conventions of the British murder mystery. It's handled with delicacy and a certain amount of unflinching courage, but tight plotting, high stakes and intriguing mystery helps. I did work out who did it, but only a chapter or so ahead of our heroines. Maybe they'd let me join the Detective Society?
