the subject be world war ii and robert ryan be a rejected soldier whom lupino hire a handyman . she be a war widow . the set be limited but the acting make up for this . robert ryan be conflict represent one moment he seem nice and then confuse about where he live . at first lupino try to help him . he seem troubled but nothing more dangerous . but how do we know . the suspense build . i truly enjoy film like this and which rely on the human element for suspense . what be this man capable of . there be some scene with o. z. whitehead and dee pollock a an annoy grocery boy who see something be wrong . we keep think she will be help and then ryan personality turn again . he become like a jekyll or hyde character and eventually chase lupino with a knife . worth watch for these two superb actor . positive .
