Does anyone recognise the following plot from a short story I read many many years ago and cannot place? A pilot is lost at night, near Holland and picks up phantom radio broadcasts from Luftwaffe night fighter ground control using a callsign "dragonfly control". Its not Frederick Forsyth's "The Shepherd" (but that one is somewhat similar)... sort of a ghost story in that it's set post war. No one else I've asked has a clue what the story is called, or who wrote it!
