This has always been one of my favorite episodes of Hammer House of M & S, and a it's a bit of classic!
Two years after a paranormal experience in their Brighton hotel room, Frank and Sylvia Daly settle down to spend the final night in their now empty London apartment - before jetting off the next day to a new life in Botswana, where Frank has been transferred for his job.
But their night is far from peaceful - the paranormal apparitions return, this time a bit closer to home, and soon they find themselves in the middle of a horror story - bearing witness to a wicked crime that appears to have involved former tenants of their apartment.
Was it all just a dream - or did they really see what thought?
The tension builds nicely in this claustrophobic story, as we learn more and more as to the fate of the poor old woman Frank and Sylvia first saw in Brighton. Christopher Cazenove and Carol Lynley make a convincing terrified couple, caught up in a real-life nightmare - with good support from the friendly neighbors upstairs in the shape of David Healy and Judy Loe (who was of course the widow of the late Richard Beckinsale).
This is an unusual and suspenseful story, which provides as excellent and surprising twist at the end which is well worth the wait. Highly recommended!
