I looked into his eyes; in their black depths was almost entreaty.
How haunting they were, and beseeching.

"Will you take my place?" he begged. "Are you willing to give up
all that God gives to the fortunate? Will you give up your
practice? Will you hold out to the end? Never surrender? Will--"

"You mean will I take this ring?"

He nodded.

it to you without the warning. Either your death or that of Dr.
Holcomb. It is not a simple jewel. It defies description. It takes
a man to wear it. It is subtle and of destruction; it eats like a
canker; it destroys the body; it frightens the soul--"

"An ominous piece of finery," I spoke. "Wherein--"

But Watson interrupted. There was appeal in his eyes.
