Gerald Glaister pitched the series to the Controller of BBC1 when he shared a lift with him at the BBC Headquarters. By the time the lift reached the Controller's floor, Glaister had himself a deal.

Series creator Gerald Glaister served as an RAF pilot during the Second World War and survived over 100 sorties over enemy lines.

The character of Kessler is loosely based on Nazi war criminal Klaus Barbie.
