The theme of a murder being witnessed by someone who no one believes, is based on the familiar concept of "cry wolf once too often and no one will believe you when you're telling the truth". Here it's played to the nth degree by an excellent cast--Bobby Driscoll, Barbara Hale, Arthur Kennedy, Ruth Roman and Paul Stewart--and directed in realistic, gritty style by Ted Tetzlaff. The New York tenement setting is an absorbing environment for this chilling tale of a boy who is in danger when the murderers know they have been seen--and must come to grips with his situation without the aid of his parents or police. Based on a Cornell Woolrich story, it's so tight and suspenseful for the length of its running time that it effectively projects the dark, nightmare world where one's worst childhood fears can come true. With the dark ambiance of lower East Side tenaments as its setting, danger and death seem to entrap the boy in every lurking shadow until his ultimate pursuit by the killers. This is a modest thriller that achieves a maximum of suspense thanks to the skillful performance by child star Bobby Driscoll and bears a resemblance to other Woolrich stories, as for example 'Rear Window'. Barbara Hale and Arthur Kennedy register strongly as the parents. Ruth Roman and Paul Stewart are a chilly pair as the neighbors from hell.
