Sofa Shelf - Retired Murder

One book this week:

The Murder of Roger Ackroyd

Poirot has retired from unravelling murder mysteries, but they seem to follow him around. This is one that I remember seeing on the TV, in fact it might have been the first Poirot that I had seen. I do know who the murderer is, but I enjoyed the TV version so much that I want to see how close it is to the book.
