Old Book Search - The Hero of Crampton School?

I'm searching for a book for my Grandma, she remembered the title as being 'The Hero of Crampton School', I cannot find it online, can anyone shed some light on what this might be? Is there anything similar in name, perhaps I have misspelt it?

Any information about where I might find a copy would also be very much appreciated, thanks!

The only clues I can give you are that it is likely to be an English book, probably published before 1950, but possibly much older.

Really any information would be helpful.
