We open with a woman walking up the stairs, turning to find a person standing in the doorway and - boom! The police arrive at the rural cottage and we discover that she was the wealthy wife of struggling painter "Howard" (Emyr Jones). Was everything in their marriage happy? Well it falls to "Insp. Gregory" (Patrick Holt) to get to the bottom fo things - a task made more complicated when one of the artist's models goes missing and that's before we get quite a twist to throw the plates in the air and leave us with a rather jumbled and overly contrived mystery. The remainder of the hour seems designed to showcase the acting talents of Honor Blackman rather than deliver a plausible mystery and by the end I'd rather lost interest. It's a low budget affair which doesn't help, but Peter Maxwell's rather staccato and lacklustre direction makes heavy weather of this, sorry.
