This movie is strangely good even though the story has been done 100 times! It stars James Mason who is suspended from his job as Naval commander,for being suspected of being a Nazi spy, he is innocent though and must prove it, so off he goes to Blackpool to start his investigations. One of his ex girlfriends has gone missing and he is told to meet her at Orchard Cottage, here he meets Joyce Howard who is visiting her uncles who live at the cottage but she finds the murdered body of this ex girlfriend and of course thinks that Mr.mason is the murderer,she goes to the police and reports it but when the police go with them to see the body has mysteriously vanished,where is it? Who has moved it? A nice little story unfolds and is worth watching even though the plot is obvious. James Mason is brilliant and very very good looking so is a must for all his fans!!! I recommend it heartily!!
