pursued the thief; had struggled with him; they had each tugged
at the coronet, their united strength causing injuries which
neither alone could have effected. He had returned with the
prize, but had left a fragment in the grasp of his opponent. So
far I was clear. The question now was, who was the man and who
was it brought him the coronet?

"It is an old maxim of mine that when you have excluded the
impossible, whatever remains, however improbable, must be the
truth. Now, I knew that it was not you who had brought it down,
so there only remained your niece and the maids. But if it were
the maids, why should your son allow himself to be accused in
their place? There could be no possible reason. As he loved his
cousin, however, there was an excellent explanation why he should
retain her secret--the more so as the secret was a disgraceful
one. When I remembered that you had seen her at that window, and
how she had fainted on seeing the coronet again, my conjecture
became a certainty.

"And who could it be who was her confederate? A lover evidently,
for who else could outweigh the love and gratitude which she must
feel to you? I knew that you went out little, and that your
circle of friends was a very limited one. But among them was Sir
George Burnwell. I had heard of him before as being a man of evil
reputation among women. It must have been he who wore those boots
and retained the missing gems. Even though he knew that Arthur
had discovered him, he might still flatter himself that he was
safe, for the lad could not say a word without compromising his
own family.
