An episodic collection of adventures, following Syn's adventures in his guise as the Scarecrow of Romney Marsh, in which he foils all attempts to catch him and to break up the Dymchurch smugglers.
The Nightriders, the most successful smuggling gang in Kent, have outwitted first every customs officer sent against them, and then the army. Nobody could imagine that their mysterious leader "The Scarecrow" could possibly be the mild-mannered vicar of Dymchurch, Dr Syn.
