Ralph Strakey is a friend of George Owdon in BS and hence an enemy of The Coot Club. He is visiting at George's uncle's in Horning, and for most of BS is just "George's friend" or "the other big boy" except for "Come on, Ralph" (BS4) and "You saw him, didn't you, Ralph" (BS29); his surname is not revealed until the last chapter (BS32).
It is not stated where he is from, or whether he is a Norfolk Coot like George.
In Frank Farland's home George gives Ralph an "angry look" when Ralph refers to the "great flare" that Bill set off to get the photograph (BS32). Earlier Ralph is astute enough to say to George "What's the name of that kid? We've both got to say we saw the same one" (BS29).
