Arthur Ransome Wiki

Police appear often in the Swallows and Amazons series:

Captain Flint was in court once, for a fancy for policeman's helmets .... on boat-race night, in a year when Oxford won (ML16).

Timothy asks Nancy How do the police come into it? Once they're in, you never know where they'll stop. She asks him What do you know about it? Have you ever been wanted by them before? and he replies Only in Peru .... Did your Uncle Jim never tell you about the time when he and I ... Oh, never mind about that. Go on . What sort of a mess are we all in now? (PM21).

Arthur Ransome often portrays the Police as mildly ridiculous, perhaps like his character Hurst he is favouring The Unofficial Side.
