Don’t remember who named them but think it was Mike—I was merely a Sherlock Homes fan whereas he really did think he was Sherlock Holmes’s brother Mycroft . . . nor would I swear he was not; "reality" is a slippery notion. Kids did not call themselves that; they had their own play gangs with own names. Nor were they burdened with secrets which could endanger them; Sidris left it to mothers to explain why they were being asked to do these jobs save that they were never to be told real reason. Kids will do anything mysterious and fun; look how many of their games are based on outsmarting.
