Two more cases for the moustachioed Belgian sleuth. In 'The Tragedy at Marsdon Manor' Hercule Poirot (David Suchet) and his side-kick Captain Hastings (Hugh Fraser) are called in to investigate a murder at a hotel. Can it be a case of black magic, natural causes or ghosts? Poirot is the man to find out. Whilst in 'The Double Clue' the duo are asked by Inspector Japp to help in solving four robberies that have taken place in high society circles.
