Agatha Christie's the Pale Horse

Both parts of the television crime drama based on the novel by Agatha Christie.

When Mark Easterbrook (Rufus Sewell) finds himself in the frame for the murder of a young woman, there seems no way to prove his innocence other than solving the mystery of the death himself.

Matters are complicated further when Mark realises that the people listed on a piece of paper recovered from the woman's body appear to be dying one by one.

Can he get to the bottom of the riddle before his time is up?
