Complete with a genealogical tree, a dubious will, and a family full of potential murderers.

Agatha Christie is the most widely published author of all time, outsold only by the Bible and Shakespeare. Her books have sold more than a billion copies in English and another billion in a hundred foreign languages. She died in 1976.

When Cora Lansquenet is savagely murdered with a hatchet, the extraordinary remark she made the previous day at her brother Richard's funeral suddenly takes on a chilling significance. At the reading of Richard's will, Cora was clearly heard to say, "It's been hushed up very nicely, hasn't it....But he was murdered, wasn't he?"

In desperation, the family solicitor turns to Hercule Poirot to unravel the mystery.
