Hôtel de Liège--in time of peace a resort of _commis-voyageurs_ of
the better class. It boasted a roomy hall, out of which opened two
coffee-rooms, converted by us into guard- and mess-room. A large
drawing-room on the first floor overlooking the street served me for
sleeping as well as working quarters, and to reach it I must pass the
_entresol_, where a small apartment had been set aside for occasional
uses. We made it, for instance, our ante-room, and assembled there
before mess; a few would retire there for smoking or card-playing;
during the day it served as a waiting-room for messengers or any one
whose business could not be for the moment attended to.

I had paused at the entrance to put some small question to the sentry,
when I heard the crash of a chair in this room, and two voices broke
out in fierce altercation. An instant after, the mess-room door
opened, and Captain Murray, without observing me, ran past me and
up the stairs. As he reached the _entresol_, a voice--my
brother's--called down from an upper landing, and demanded, "What's
wrong there?"

"I don't know, Major," Captain Murray answered, and at the same moment
flung the door open. I was quick on his heels, and he wheeled round in
some surprise at my voice, and to see me interposed between him and
my brother, who had come running downstairs, and now stood behind my
shoulder in the entrance.

"Shut the door," I commanded quickly. "Shut the door, and send away
any one you may hear outside. Now, gentlemen, explain yourselves,
please."

Mr. Urquhart and Mr. Mackenzie faced each other across a small table,
