In Biggles Hunts Big Game, Squadron Leader Crane was in charge of the care and maintenance party at Delmar, an airfield in Hertfordshire which the R.A.F. had recently closed. Biggles moved his operations to Delmar to evade the surveillance efforts of the counterfeiting gang he was investigating. There he found that Crane had received his orders for Biggles and had accomodation and facilities prepared for him. Biggles observed that Crane was "a good type", a professional officer who did what he was told and didn't ask questions.
