romise faithfully."

"Those are rather unusual terms, Miss Baxter," said the Chief; "but I
accede to them, the more willingly as we have found that all the gold is
still in the Treasury, as you said it was."

"Very well, then, the first favour is that I shall not be called to
give testimony when an inquest is held on the body of Professor Carl
Seigfried."

"You amaze me!" cried the Director; "how did you know he was dead? I had
news of it only a moment before I left my office."

"I was with him when he died," said Jennie simply, which statement
drew forth an exclamation of surprise from both the Princess and the
Director. "My next request is that you destroy utterly a machine which
stands on a table near the centre of the Professor's room. Perhaps the
instrument is already disabled--I believe it is--but, nevertheless, I
shall not rest content until you have seen that every vestige of it is
made away with, because the study of what is left of it may enable some
other scientist to put it in working order again. I entreat you to
attend to this matter yourself. I will go with you, if you wish me
to, and point out the instrument in case it has been moved from its
position."

"The room is sealed," said the Director, "and nothing will be
touched until I arrive there. What is the nature of this instrument?"

"It is of a nature so deadly and destructive that, if it got into the
hands of an anarchist, he could, alone, lay the city of Vienna in
ruins."

"Good heavens!" cried the horrified official, whose bane was the
anarchist, and Jennie, in mentioning this particular type of criminal,
had builded better than she knew. If she had told him that the
Professor's invention might enable Austria to conquer all the
surrounding nations, there is every chance that the machine would have
been carefully preserved.

"The explosion in the Treasury vaults," continued Jennie, "was
accidentally caused by this instrument, although the machine at the
moment was in a garret half a mile away. You saw the terrible effect of
that explosion; imagine, then, the destruction it would cause in the
hands of one of those anarchists who are so reckless of consequences."

"I shall destroy the instrument with my own hands," asserted the
Director fervently, mopping his pallid brow.

Jennie then went on, to the increasing astonishment of the Princess and
the Director, and related every detail of her interview with the late
professor Carl Seigfried.
