to return to Europe to buy fresh stock. Doctor Schmidt knew that, and he
came to see me just before I sailed. He first thought of writing a very
long letter. Afterwards he changed his mind. He wrote only these few
lines I brought, but he told me those other things."

"You have remembered all that he told you?" Dominey asked.

"I can think of nothing else," was the reply, after a moment's pause.
"The whole affair has been a great worry to Doctor Schmidt. There are
things connected with it which he has never understood, things connected
with it which he has always found mysterious."

"Hence your presence here, Johann Wolff?" Seaman asked, in an altered
tone.

The visitor's expression remained unchanged except for the faint
surprise which shone out of his blue eyes.

"Johann Wolff," he repeated. "That is not my name. I am Ludwig Miller,
and I know nothing of this matter beyond what I have told you. I am just
a messenger."

"Once in Vienna and twice in Cracow, my friend, we have met," Seaman
reminded him softly but very insistently.

The other shook his head gently. "A mistake. I have been in Vienna once
many years ago, but Cracow never."

"You have no idea with whom you are talking?"
