Delve Special was a UK BBC Radio 4 comedy starring Stephen Fry as investigative reporter David Lander. It ran for four series from 1984 to 1987, each series being four 30-minute episodes long. It was written by Tony Sarchet and produced by Paul Mayhew-Archer. The first series was wiped by the BBC but has since been found and consisted of a four-part investigation into the proposed building of London's third airport in "Shifton", a small village situated 'just to the north east of Birmingham', and the alleged bribery and corruption that accompanied the choice of location and building contractor.
