nerves, Godfrey. I dream about it--have regular nightmares."

He sat down opposite me, concern and anxiety in his face.

"That won't do," he protested. "You must go away somewhere--take a
rest, and a good long one."

"A rest wouldn't do me any good, as long as this mystery is
unsolved," I said. "It's only by working that I can keep my mind off
of it."

"Well," he smiled, "just to oblige you, we will solve it first,
then."

"Do you mean you know...."

"I know who the Great Unknown is, and I'm going to tell you
presently. Day after to-morrow--Wednesday--I'll know all the rest.
The whole story will be in Thursday morning's paper. Suppose you
arrange to start Thursday afternoon."

I could only stare at him. He smiled as he met my gaze.

"You're looking better already," he said, "as though you were taking
a little more interest in life," and he helped himself to a cigar.

"Godfrey," I protested, "I wish you would pick out somebody else to
practise on. You come up here and explode a bomb just to see how high
I'll jump. It's amusing to you, no doubt, and perhaps a little
instructive; but my nerves won't stand it."
