From 1938 to 1968, Francis Durbridge's incomparably suave amateur detective Paul Temple and his glamorous wife Steve solved case after baffling case in one of BBC radio's most popular series. Sadly, only half of Temple's adventures survive in the archives. In 2006 BBC Radio 4 brought one of the lost serials back to life with Crawford Logan and Gerda Stevenson as Paul and Steve. Using the original scripts and incidental music, and recorded using vintage microphones and sound effects, the production of Paul Temple and the Sullivan Mystery aimed to sound as much as possible like the 1947 original might have done if its recording had survived. The serial proved so popular that it was soon followed by three more revivals, Paul Temple and the Madison Mystery, Paul Temple and Steve, and A Case for Paul Temple. Now it's the turn of Paul Temple and the Gregory Affair from 1946, in which Paul and Steve come to the aid of a baffled Scotland Yard in pursuit of a deadly and mysterious criminal mastermind. Not only has the recording disappeared but also the scripts of Episodes 1, 2 and 6. This new production is made possible by the recent discovery by a colleague in Norwegian radio of a complete set of scripts in an old store cupboard in Oslo. It is 1946, and the whole country is shocked by the disappearance of a young woman who, according to a note found at the scene of the crime, is the victim of a certain 'Mr Gregory'. When a second girl disappears, Sir Graham Forbes of Scotland Yard appeals to Temple and Steve for help. Their investigations take them from a lonely Yorkshire clifftop to the Blitz-damaged East End, from a gangster-run Mayfair nightclub to a deserted warehouse on the Thames, always with danger round the corner.
