"I really must. Do not forget that I have been used to taking care of myself in a bigger city than Vienna is, and I shall be quite safe. You will please excuse my absence from the dinner-table to-night."

"Nonsense, Jennie! You cannot be allowed to roam round Vienna in that Bohemian way."

"Then, Princess, I must go to an hotel, for this roaming round is strictly necessary, and I don't want to bring the Palace Steinheimer into disrepute."

"Jennie, I'll tell you what we will do; we'll both bring it into disrepute. The Prince is dining at his club to-night with some friends, so I shall order the carriage, and you and I will roam round together.

You will let me come, won't you? Where are you going?"

"I am going to the Graubenstra.s.se to see Herr Feltz."

"Oh, I know Herr Feltz, and a dear old man he is; he will do anything for me. If you want a favour from Herr Feltz, you had better take me with you."

"I shall be delighted. Ah, here comes the tea! But what is the use of ordering the carriage? we can walk there in a very few minutes."

"I think we had better have the carriage. The Prince would be wild if he heard that we two went walking about the streets of Vienna at night. So, Jennie, we must pay some respect to conventionality, and we will take the carriage. Now, tell me where you have been, and what you have seen, and all about it." Over their belated decoction of tea Jennie related everything that had happened.

"And what do you expect to learn from the a.n.a.lysis at the chemist's, Jennie?"

"I expect to learn something that will startle 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 a.n.a.lysis 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 a.n.a.lysis 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 a.n.a.lysis 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 Graubenstra.s.se, and were told that the chemist could not be seen in any circ.u.mstances. 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 a.n.a.lysis now, I'll warrant," whispered the Princess to her companion. In a short time Herr Feltz himself appeared.

He greeted the Princess with most deferential respect, but seemed astonished to find in her company the young woman who had called on him a few hours previously with the Director of the Police.

"I wanted to ask you," said Jennie, "to finish your a.n.a.lysis somewhat earlier than four o'clock to-morrow. I suppose it can be done?"

The man of science smiled and looked at her for a moment, but did not reply. "You will oblige my friend, I hope," said the Princess.

"I should be delighted to oblige any friend of your Highness," answered the chemist slowly, "but, unfortunately, in this instance I have orders from an authority not to be disputed."

"What orders?" demanded the Princess.

"I promised the a.n.a.lysis at four o'clock to-morrow, and at that hour it will be ready for the young lady. I am ordered not to show the a.n.a.lysis to anyone before that time."

"Those orders came from the Director of Police, I suppose?" The chemist bowed low, but did not speak.

"I understand how it is, Jennie; he came here immediately after seeing you home. I suppose he visited you again within the hour after he left with this young lady--is that the case, Herr Feltz?"

"Your Highness distresses me by asking questions that I am under pledge not to answer."

"Is the a.n.a.lysis completed?"

"That is another question which I sincerely hope your Highness will not press."

"Very well, Herr Feltz, I shall ask you a question or two of which you will not be so frightened. I have told my friend here that you would do anything for me, but I see I have been mistaken."

The chemist made a deprecatory motion of his hands, spreading them out and bowing. It was plainly apparent that his seeming discourtesy caused him deep regret. He was about to speak, but the Princess went impetuously on.

"Is the Director of Police a friend of yours, Herr Feltz? I don't mean merely an official friend, but a personal friend?"

"I am under many obligations to him, your Highness, and besides that, like any other citizen of Vienna, I am compelled to obey him when he commands."

"What I want to learn," continued the Princess, her anger visibly rising at this unexpected opposition, "is whether you wish the man well or not?"

"I certainly wish him well, your Highness."

"In that case know that if my friend leaves this shop without seeing the a.n.a.lysis of the material she brought to you, the Director of Police will be dismissed from his office to-morrow. If you doubt my influence with my husband to have that done, just try the experiment of sending us away unsatisfied."

The old man bowed his white head.

"Your Highness," he said, "I shall take the responsibility of refusing to obey the orders of the Director of Police. Excuse me for a moment."

He retired into his den, and presently emerged with a sheet of paper in his hand.

"It must be understood," he said, addressing Jennie, "that the a.n.a.lysis is but roughly made. I intended to devote the night to a more minute scrutiny."

"All I want at the present moment," said Jennie, "is a rough a.n.a.lysis."

"There it is," said the chemist, handing her the paper. She read,----

Calcium 29 Iron 4 Quartz ]

Feldspar ] 27 Mica ]

Gold 36-1/2 Traces of other substances 3-1/2 ------- Total 100

Jennie's eyes sparkled as she looked at the figures before her. She handed the paper to the Princess saying,--
