Audiobook Title:
The Clocks (Unabridged)
By: Agatha Christie

What intrigued Poirot about the case was the time factor. Although in a state of shock, Sheila clearly remembered having heard a cuckoo clock strike 3.00. Yet, the four other clocks in the living room all showed the time as 4.13. Even more strange: only one of these clocks belonged to the owner of the house.
