Define "Fireman"
In *The Honourable Schoolboy*, there's a piece of jargon I wanted to check the definition of.
When Luke visits Craw in his retirement, quite near the beginning of the book, Luke ends up bumping into George Smiley, who is visiting Craw.
Craw describes Smiley as a "fireman", along with some stuff about how he's an influencial back room boy with his newspaper.
Exactly what's meant by "fireman"? I'm guessing it's something along the lines of a newspaper editor who can deal with problems as they arise? Or have I got the wrong end of the stick entirely, your graces?
