"I can make you another," said the locksmith.
"I want to open it now. Haven't you got some already made?"
"Plenty. But how will you know the size?"
"Give me half a dozen to try, and I will bring back those that don't suit."
"All right. Is your lock a large one?"
"Not very. About medium," said Maurice, hazarding a guess.
The locksmith picked out eight keys, of various sizes, and handed them to Maurice.
"I will bring them back safe," said he.
"All right. I don't think you'll run off with them."
"Now for it," said Maurice. "I think one of these keys must fit."
