In literature, who was the best known pupil of Greyfriars School?

GageahRage777, If you're not British or from one of the British dominated Commonwealth countries it is entirely probable that you won't have. In fact I doubt if many British people under 50 would know the answer. The Greyfriars stories were at their most popular between the wars and the TV series ran in the 50's.

only greyfriar I could think of was greyfriar's Bobby.

SloaneRanger2019, somewhat true. I remember him because I used to read comics with his sister Bessie. At my school, a Bessie Bunter was a chubby girl.

Gray Friers is also Glass made in London

must have tapped into my inner Brit.

Funny is as funny does.

This is well before my time, these obscure questions should be classified as hard not moderate difficulty.
