that side was indeed without a break. Some vines had started up it
here and there, but, for the most part, it loomed grey and bleak,
crowned along its whole length by that threatening line of broken
glass. I judged it to be twelve feet high, so that, even without the
glass, it would be impossible for anyone to get over it without
assistance. As I stood there looking at it, resenting the threat of
that broken glass, and pondering the infirmity of character which such
a threat revealed, it suddenly struck me that the upper part of the
wall differed slightly from the lower part. It was a little lighter in
colour, a little newer in appearance; and, examining the wall more
closely, I discovered that originally it had been only eight or nine
feet high, and that the upper part had been added at a later date--and
last of all, of course, the broken glass!

As I turned back, at last, toward the house, I saw someone coming up
the drive. In a moment, I recognised Swain, and quickened my steps.

"You made good time," I said.

"Yes, sir; I was fortunate in catching an express and not having to
wait for the trolley."

"We'd better go into the house," I added. "I have a message for you--a
confidential message."

He glanced at me quickly, but followed silently, as I led the way into
Godfrey's study and carefully closed the door.

"Sit down," I said, and I sat down myself and looked at him.
