Delve Special was a UK BBC Radio 4 comedy starring Stephen Fry as investigative reporter David Lander.
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.
David Lander's investigative technique was usually somewhere between the questionable and the illegal - during each episode he also displayed some degree of ineptitude or lack of understanding in the subject matter he was reporting on.
Actors appearing in Delve Special included: Tony Robinson, Felicity Montagu, Stephen Frost, Mark Arden, Jack Klaff, Harry Enfield, Dawn French, Brenda Blethyn, Arthur Smith, Janine Duvitski, Philip Pope, Robert Bathurst and Andrew Sachs.
A follow-up television version ran for two series: This is David Lander (starring Stephen Fry) in 1988, and This is David Harper (starring Tony Slattery) in 1990 - Fry being unavailable for the second series due to other commitments.
