oundations of his
faith.

We entered the Hatton Garden office side by side; in his anxiety not to
let me get before him, Pugh actually clung to my arm. The office was
divided into two parts by a counter which ran from wall to wall. I
advanced to a man who stood on the other side of this counter.

"I want to sell you a diamond."

"_We_ want to sell you a diamond," interpolated Pugh.

I turned to Pugh. I "fixed" him with my glance.

"_I_ want to sell you a diamond. Here it is. What will you give me for
it?"

Taking the crystal from my waistcoat pocket I handed it to the man on the
other side of the counter. Directly, he got it between his fingers, and
saw that it was that he had got, I noticed a sudden gleam come into his
eyes.

"This is--this is rather a fine stone."

Pugh nudged my arm.

"I told you so." I paid no attention to Pugh. "What will you give me for
it?"

"Do you mean, what will I give you for it cash down upon the nail?"

"If you can give me references, or satisfy me in any way as to your _bona
fides_, I am prepared to give you for this diamond an open check for ten
thousand pounds, or if you prefer it, the cash instead."

I stared; I was not accustomed to see business transacted on quite such
lines as those.

"We'll take it," murmured Pugh; I believe he was too much overcome by his
feelings to do more than murmur. I interposed.

"My dear sir, you will excuse my saying that you arrive very rapidly at
your conclusions. In the first place, how can you make sure that it is a
diamond?"

The man behind the counter smiled.

"I should be very ill-fitted for the position which I hold if I could not
tell a diamond directly I get a sight of it, especially such a stone as
this."

"But have you no tests you can apply?"

"We have tests which we apply in cases in which doubt exists, but in this
case there is no doubt whatever. I am as sure that this is a diamond as I
am sure that it is air I brea
