Fletcher Markle's eight early Thrillers are all fairly weak but "The Mark of the Hand" has so little going for it that the second episode, "Child's Play," almost looks better by comparison. A gunshot rings out and standing over the corpse holding the murder weapon is an 8 year old girl who steadfastly refuses to comment on what happened, since she always seems to get into trouble no matter what she says. Shepperd Strudwick plays the worried father and Jessie Royce Landis plays the grandmother. Judson Pratt made a career out of playing police investigators like this one here (and also in 1958's "Monster on the Campus"), but it's up to him to keep interest from flagging. Every character is so clichéd and the climax so predictable that director Paul Henreid can do little with it. The little girl is played by Terry Burnham, who later appeared (unbilled) as another endangered child in episode 22, "The Fingers of Fear," finally giving up on her career by 1971.
