From the back cover:

When socialite Lady Angkatell organises a weekend's entertainment at her English country house, The Hollow, it seems she has thought of everything; the capable butler, the requisite number of kitchen maids - in fact, the only thing she seems to have overlooked is the fact that most of her guests loathe each other.

A far-from-warm welcome greets Hercule Poirot as he arrives for lunch - instead, a man lies dying by the swimming pool, as a gun sinks slowly to the bottom.

Happy reading!
