Initially there are shades of 'Jeeves and Wooster' with Murray Selwyn and his servant Twigg in this mildly amusing crime-comedy. Selwyn arrives home one day by taxi and Twigg carries his purchases into the house. However they soon discover they have also acquired a briefcase stuffed with five pound notes left in the taxi by the previous passenger. These are actually forged notes made on engraved plates by an expert engraver called Joe Pasquale who is currently doing 10 years in Dartmoor. The plates were never found by the police but they also fall into the possession of Selwyn by circumstances too complicated to explain here. The rest of the film is concerned with a criminal gang's efforts to acquire the plates (ably led by Elwyn Brook-Jones) and their frustration at always being one step behind the location of the plates.
Throughout the film, circumstances lead the police to suspect Selwyn of being implicated in the crime and much of the humour involves his truthful explanations to the incredulous police Inspector Archer (nicely played by the usually staid Clive Morton). Overall the acting is good with Guy Middleton as Selwyn being his usual suave self and the plot fast moving.
Apparently this ultra-rare film has not been seen since its initial release but if you're an aficionado of British second features of the 1950s I venture to say you will not be disappointed with this one
