s. And there you are again in
another puzzle; what could a respectable country gentleman like Mr.
Blank (we'll call him that if you don't mind) want in such a very queer
house as Number 20? It's altogether a very odd case, isn't it?"

"It is indeed, Austin; an extraordinary case. I didn't think, when I
asked you about my old friend, I should strike on such strange metal.
Well, I must be off; good-day."

Villiers went away, thinking of his own conceit of the Chinese boxes;
here was quaint workmanship indeed.

THE DISCOVERY IN PAUL STREET

A few months after Villiers' meeting with Herbert, Mr. Clarke was
sitting, as usual, by his after-dinner hearth, resolutely guarding his
fancies from wandering in the direction of the bureau. For more than a
week he had succeeded in keeping away from the "Memoirs," and he
cherished hopes of a complete self-reformation; but, in spite of his
endeavours, he could not hush the wonder and the strange curiosity that
the last case he had written down had excited within him. He had put

in. And how are you, Villiers? Want any advice about investments?"

"No, thanks, I fancy everything I have in that way is pretty safe. No,
Clarke, I have really come to consult you about a rather curious matter
that has been brought under my notice of late. I am afraid you will
think it all rather absurd when I tell my tale. I sometimes think so
myself, and that's just what I made up my mind to come to you, as I
know you're a practical man."

Mr. Villiers was ignorant of the "Memoirs to prove the Existence of the
Devil."

"Well, Villiers, I shall be happy to give you my advice, to the best of
my ability. What is the nature of the case?"

"It's an extraordinary thing altogether. You know my ways; I always
keep my eyes open in the streets, and in my time I have chanced upon
some queer customers, and queer cases too, but this, I think, beats
all. I was coming out of a restaurant one nasty winter night about
three months ago; I had had a
