The adaptation of "The Thirty-Nine Steps" was broadcast last night on BBC One. It wasn't a patch on the 1935 Hitchcock film, but nevertheless a perfectly entertaining 90 minutes on a Sunday evening.

Alex doesn't feature in this too much; my best advice would be not to blink!
The film is available here on the iPlayer until the 4th of January.
