Francis Durbridge shines through with his special knack for women mysteries and their magic presence for being absent, you are reminded both of the Paul Temple series and "Melissa" and other spellbinding thrillers with mystical ladies, and here you have two of them murdered while one of them shows up not being murdered at all.
The intrigue is spun around a portrait, a weird old man commissions Robert Beatty, a poor painter and brother of the first casualty of the racket, to paint his lost daughter from a picture of her, which task gets him into thorough trouble, especially since one of his earlier models is found murdered in his flat.
It's not a bad film although somewhat superficial, of such an intrigue Hitchcock would have brought out a masterpiece, the action is a bit thick as too many things are happening at the same time and too many threads are being woven together in some confusion, as there is another casualty of a man jumping out of a window and lots of fisticuffs which at least twice completely demolishes the painter's entire flat - there is not much space to fight, but they do it the more thoroughly.
In brief, a very entertaining thriller with some magic in it, but you would have preferred the first girl (Josephine Griffin) to Terry Moore, but that's a matter of personal taste..
