The Switch

Customs man Anthony Steel is looking for smuggled watches with the aid of inspector Dermot Walsh. Also Magazine model Zena Marshall is vacationing in France, when charming Arnold Diamond inveigles her to lunch and a drive. Returning home to London, she finds Conrad Phillips has sublet her apartment. His red Sunbeam, identical to the loaner from her service station has been stolen from her garage. Sparks fly, and the next night, her red Sunbeam is also stolen from her garage. The following night, she is dining with Phillips. After he drops her off, she finds herself confronted with a couple of nasty men who want the watches.

It's a nicely set up melodrama, with gallant cops, threatening goons, secret passages, and Dawn Beret playing as annoying a specimen of Muta Flava as you'd never hope to meet. Susan Shaw and Jimmy Hanley have small roles.
