That Agatha Christie. She fools me every time. I just finished reading A Pocket Full of Rye and was caught unawares as usual. The murders are based on the nursury rhyme:
The first to be murdered is Rex Fortescue "in his counting house," the second is his wife "eating bread and honey," and the third is Gladys, the maid, who was "in the garden hanging out the clothes."
Suspects include two sons and their wives, a mysterious housekeeper, two lovers, a daughter, and of course a butler. It is all very classy and clever as usual. Miss Marple makes an appearance and solves the crimes along with some help from Inspector Neele.
A lovely bedtime read.
