Charlie Drake's expert locksmith never goes anywhere without his emergency tool kit, repeatedly gets duped into unknowingly pulling robberies by a suave Dennis Price and ends up in the nick with Percy Herbert and (in a bit part) Ronnie Barker.
Easily this comic's best and most sophisticated vehicle, a daft and sometimes inspired farce with fine support from George Sanders and Eddie Bryne as rival master crooks and from a young Nyree Dawn Porter who wears a winning smile throughout. Surprisingly good.
