es, Excellency. The person who said he was Herr Renwick was tall,
attired in black clothing, and carried an umbrella."

"Who brought the note?"

"As to that--I do not know."

The major-domo moved majestically away, but the Turkish porter who stood
listening, broke in.

"If your Excellency will permit. It was I who received the note, late
this afternoon. It was brought by a woman in a _yashmak_--a Turkish
woman. Of course I could not know her, since one looks with averted eyes
upon the women of Islam, but she would have come from the Turkish
quarter of the town--from beyond the Carsija--perhaps. I do not know. I
can say no more."

Renwick paused irresolutely and giving the man a fee, went out of the
hotel into the street, mingling with the crowds upon Franz Josef Street,
where but a few hours before on a nearby corner, the Archduke and
Duchess had met their deaths. Deciding that at all hazards he must
remain inconspicuous while he thought out a plan, he crossed the river
and went into a small park, where he sank wearily into a bench and
buried himself in new speculations.

A pipe and tobacco soothed, if they failed to stimulate his faculties.
He had reached an _impasse_. What if the Enigma in black were playing
some deep game of his own with regard to Marishka? What if, after all,

had the Wilhelmstrasse? And yet such a theory was hardly plausible, for
if Linke were interested in Marishka's silence he would also be
interested in Renwick's, and this being the case, the easiest way out of
the business would have been to have dropped Renwick into some deep pool
of the Save or the Bosna while he slept. Herr Linke puzzled Renwick, but
reason informed him that the unknown limousine chap was the greater
menace both to Marishka and himself. That he held Renwick's life cheaply
was indicated by the frequent attempts upon it in Vienna and in Bohemia
and the mere fact that he had twice failed was no sign that a third
attempt might not be successful. The most unfavorable phase of the
situation was that the German agent knew Renwick by sight, and would
have every opportunity of following him to some secluded spot--shooting
him in the back and escaping into a nearby street before the excitement
subsided. What did the German agent look like? He might pass the fellow,
elbow to elbow, and the E
