ought me of the open door of the
museum. Probably he had gone there to look for a way out. This would
never do. The plate I cared not a fig for, but the museum specimens were
a different matter; and he might damage them from sheer malice.

"I unbolted the door, entered and shut it again, locking it on the
inside and dropping the key into my pocket. I had just done so when he
appeared at the museum door, eyeing me warily and unobtrusively slipping
a knuckle-duster on his left hand. I had noted that he was not
left-handed and drew my own conclusions as to what he meant to do with
his right. We stood for some seconds facing each other and then he began
to edge towards the door. I drew aside to let him pass and he ran to the
door and turned the handle. When he found the door locked he was
furious. He advanced threateningly with his left hand clenched, but then
drew back. Apparently, my smiling exterior, coupled with my previous
conduct, daunted him. I think he took me for a lunatic; in fact, he
hinted as much in coarse, ill-chosen terms. But his vocabulary was very
limited, though quaint.

"We exchanged a few remarks and I could see that he did not like the
tone of mine. The fact is that the sight of the knuckle-duster had
changed my mood. I no longer felt playful. He had recalled me to my
original purpose. He expressed a wish to leave the house and to know
'what my game was.' I replied that he was my game and that I believed
that I had bagged him, whereupon he rushed at me and aimed a vicious
blow at my head with his armed left fist, which, if it had come home,
would have stretched me senseless. But it did not. I guarded it easily
and countered him so that he staggered back gasping.

"That made him furious. He came at me like a wild beast, with his mouth
open and his armed fist flourished aloft as if he would annihilate me. I
tried to deal with him by the methods of Mr. Slimy Cohen, but it was
useless. He was no boxer and he had a knuckle-duster. Consequently we
grabbed one another like a pair of monkeys and sought to inflict
unorthodox injuries. He struggled and writhed and growled and kicked and
even tried to bite; while I kept, as far as I could, control of his
wrists and waited my opportunity. It was a most undignified affair. We
staggered to and fro, clawing at one another; we gyrated round the room
in a wild, unseemly waltz; we knocked over the chairs, we bumped
against the table, we banged each other's heads again
