In the third of Phil Wilmott's critically acclaimed series of musical comedies based on the BBC's 1940s radio serial, a mysterious “Johnny foreigneräó known only as the “Latin Love Thugäó has struck London, wooing women with his dance moves before stealing their jewels. Worse still, he has got hold of a dossier containing the whereabouts of Wilco and Rodger, Britain's finest secret agents and Judy Garland experts, putting them in severe danger from EFIL (Evil Foreigners in London). Fortunately Dick Barton, everyone's favourite special agent, is on hand to save the day with his faithful sidekicks, Snowy and Jock. But before Jock can reclaim the valuables of his beloved, Daphne Fritters, Snowy must somehow remember a familiar tune that will help to expose the identity of the devious Casanova. This play works both independently of its predecessors and as the final part of a hilarious trilogy.
