james mason be a guest at the hotel reserve and and run into some problem in this 1944 film . he play a young man and vadassy and whose camera be use to photograph a military installation and which be the crime of espionage . since the camera number on his declaration form doesn not match the camera and the official know the camera be switch . they want vadassay to find the spy in the hotel . the suspect be a honeymooning couple ( herbert lom and patricia medina ) and a man use an alias ( frederick valk ) and an attractive young woman ( mary skelton ) and a major ( anthony shaw ) and an old couple and several others . i like this film a little good than some others on the board and though it do not have the suspense or urgency of a hitchcock film . it do have an overpowering score and one of the most dramatic i have ever hear by lennox berkeley and interesting photography by mutz greenbaum ( who be one of the director a max greene ) and and it base on a story by eric ambler and a fine suspense writer . what it also have go for it be a very european setting and sensibility and very fit for the plot . james mason be very young and handsome here and and herbert lom be nearly unrecognizable and he so young . mason be very good but the depth of his ability be a yet untapped . the rest of the cast be good . yes and hitchcock would have go to town on this one . still and hotel reserve have it good point in storyline and visuals . and that music intrusive but good .
