Il segno del pericolo

This UK film from 1955 opens with a car racing along the road, over the cliff it goes, and bursts into flames when it hits the canyon below. Geoffrey Keen is Inspector Cobly, who is investigating the accident. We are introduced to Tim and Dave, the brothers of the deceased driver. You'll recognize "Henry" (Allan Cuthbertson) from Fawlty Towers, and whole lot of British TV. I see Hopscotch (AWESOME film) in Cuthberson's list of roles, but can't remember what he did in it. Tim (Robert Beatty) also starts checking out what's going on, and he bumps into people who have the answers, but don't want to give them up. Terry Moore stars as Alison, and seems to be at the center of all this grand adventure. Pretty entertaining. I've never seen this one before, and as of today, doesn't have any comments on the discussion board. Must be new to Turner Classics. There is a twist here and there, but nothing earth shattering. Story by Francis Durbridge, who wrote this in between all the (British) TV series for which he was known. Directed by Guy Green, who had received an Oscar for directing the 1948 Great Expectations.
