e the Director of Police."

"And what is that? Jennie, don't keep me on tenterhooks in this
provoking way. How can you act so? I shall write to Lord Donal and tell
him that you are here in Vienna, if you don't mind."

"Well, under such a terrible threat as that, I suppose I must divulge
all my suspicions. But I really don't know anything yet; I merely
suspect. The weight of that dust, when I picked up a handful of it,
seemed to indicate that the gold is still there in the rubbish heap."

"You don't mean to say so! Then there has been no robbery at all?"

"There may have been a robbery planned, but I do not think any thief got
a portion of the gold. The chances are that they entirely underestimated
the force of the explosive they were using, for, unless I am very much
mistaken, they were dealing with something a hundred times more powerful
than dynamite."

"And will the chemical analysis show what explosive was used?"

"No; it will only show of what the _debris_ is composed. It will settle
the question whether or not the gold is in that dust-heap. If it is,
then I think the Government will owe me some thanks, because the
Director of Police talked of carting the rubbish away and dumping it out
of sight somewhere. If the Government gets back its gold, I suppose the
question of who fired the mine is merely of academic interest."

"The carriage is waiting, your Highness," was the announcement made to
the Princess, who at once jumped up, and said,--

"I'll be ready in five minutes. I'm as anxious now as you are to hear
what the chemist has to say; but I thought you told me he wouldn't have
the analysis ready until four o'clock to-morrow. What is the use of
going there to-night?".

"Because I am reasonably certain that the Director of Police will see
him early to-morrow morning, and I want to get the first copy of the
analysis myself."

With that the Princess ran away and presently reappeared with her wraps
on. The two drove to the shop of Herr Feltz in the Graubenstrasse, and
were told that the chemist could not be seen in any circumstances. He
had left orders that he was not to be disturbed.

"Disobey those orders and take in my card," said the Princess.

A glance at the card dissolved the man's doubts, and he departed to seek
his master.

"He is working at the analysis now, I'll warrant," whispered the
Princess to her companion. In a short time Herr Feltz himself appeared.
He greeted the Princess with most de
