An American railroad detective bumps heads with Scotland Yard in "Whispering Smith vs. Scotland Yard " (the USA theatrical title as shown on site in all nine production stills and poster no. 12) in a film produced in England by Julian Lesser in association with Exclusive Films, Ltd. Coming to England on a vacation Whispering Smith (Ricard Carlson) is immediately involved in a case of "apparent suicide." Starting the case as a lark, Smith quickly finds himself up to his ears in mayhem, a lovely suspect, Louise Balfour (Greta Gynt), a pretty secretary , Ann Carter (Rona Anderson), and a ring of blackmailers including a crooked lawyer and a puppet fancier. Scotland Yard had found a death to be a suicide, but Smith finds it was a murder and while dodging a similar fate himself, has time for light romance with Ann Carter.
