The Trygon Factor

A Scotland Yard detective (Stewart Granger) is investigating a string of robberies and a murder, and the information he uncovers leads him to the estate of a wealthy but strange English family, who share their mansion with a group of nuns. The detective comes to suspect that neither the family nor the nuns is quite what they seem to be.

Quite an oddball mystery film that can be confusing, character motivations can be hard to fathom and there's a lack of sharpness in the plot, but on the other hand, it's strangeness can be entertaining and there's a dash of creativity at work. There's nice decor, location and a sinister atmosphere- and some black humour. Stewart Granger is his usual charming self and makes this a distracting watch.
