a superstitious yarn spun out of something
much simpler. I've sometimes thought it was a wild version of one of
those mutilation stories. They used to crop criminals' ears in the
sixteenth century."

"I hardly think it was that," answered the little man thoughtfully, "but
it is not outside ordinary science or natural law for a family to have
some deformity frequently reappearing--such as one ear bigger than the
other."

The big librarian had buried his big bald brow in his big red hands,
like a man trying to think out his duty. "No," he groaned. "You do the
man a wrong after all. Understand, I've no reason to defend him, or even
keep faith with him. He has been a tyrant to me as to everybody else.
Don't fancy because you see him sitting here that he isn't a great lord
in the worst sense of the word. He would fetch a man a mile to ring a
bell a yard off--if it would summon another man three miles to fetch
a matchbox three yards off. He must have a footman to carry his
walking-stick; a body servant to hold up his opera-glasses--"

"But not a valet to brush his clothes," cut in the priest, with a
curious dryness, "for the valet would want to brush his wig, too."

The librarian turned to him and seemed to forget my presence; he was
strongly moved and, I think, a little heated with wine. "I don't know
how you know it, Father Brown," he said, "but you are right. He lets the
whole world do everything for him--except dress him. And that he insists
on doing in a literal solitude like a desert. Anybody is kicked out
of the house without a character who is so much as found near his
dressing-room door.

"He seems a pleasant old party," I remarked.

"No," replied Dr Mull quite simply; "and yet that is just what I mean by
saying you are unjust to him after all. Gentlemen, the Duke does really
feel the bitterness about the curse that he uttered just now. He does,
with sincere shame and terror, hide under that purple wig something he
thinks it would blast the sons of man to see. I know it is so; and I
know it is not a mere natural disfigurement, like a criminal mutilation,
or a hereditary disproportion in the features. I know it is worse than
that; because a man told me who was present at a scene that no man could
invent, where a stronger man than any of us tried to defy the secret,
and was scared away from it."

I opened my mouth to speak, but Mull went on in oblivion of me, speaking
out of the cavern of his hands. "I don't m
