that a very impatient man could, until some twenty minutes had run out.
At last he addressed himself to the doorkeeper and inquired if it was a
very long way to that part of the library to which Mr Garrett had gone.

'Well, I was thinking it was funny, sir: he's a quick man as a rule, but
to be sure he might have been sent for by the librarian, but even so I
