"No, except the cab I spoke of, and the driver has accounted satisfactorily for his time that night. The absence of any conveyance is the strange part of it; and, moreover, the sentries, although pacing outside the walls of this building, heard nothing of the concussion beyond a low rumble, and those who thought of the matter at all imagined an explosion had occurred in some distant part of the city."
"Then the outside doors in the large hall above were not blown open?"
"No; the officer reports that they were locked and bolted when he examined them, which was some minutes, of course, after the disaster had taken place; for he, the officer in charge, had been thrown down and stunned, seemingly by the concussion of air which took place."
As Jennie walked down the corridor, she saw more and more of the evidences of the convulsion. The thick iron-bound door lay where it had fallen, and it had not been moved since it was lifted to get the two men from under it. Its ponderous hinges were twisted as if they had been made of glue, and its ma.s.sive bolts were snapped across like bits of gla.s.s. All along the corridor on the floor was a thick coating of dust and _debris_, finely powdered, growing deeper and deeper until they came to the entrance of the room. There was no window either in corridor or chamber, and the way was lit by candles held by soldiers who accompanied them. The scoria crunched under foot as they walked, and in the chamber itself great heaps of dust, sand and plaster, all pulverized into minute particles, lay in the corners of the room, piled up on one side higher than a man"s head. There seemed to be tons of this _debris_, and, as Jennie looked up at the arched ceiling, resembling the roof of a vaulted dungeon, she saw that the stone itself had been ground to fine dust with the tremendous force of the blast.
"Where are the remnants of the treasure chest?" she asked.
The Director shook his head. "There are no remnants; not a vestige of it is to be found."
"Of what was it made?"
"We used to have an old treasure chest here made of oak, bound with iron; but some years ago, a new receptacle being needed, one was especially built of hardened steel, constructed on the modern principles of those burglar-proof and fire-proof safes."
"And do you mean to say that there is nothing left of this?"
"Nothing that we have been able to discover."
"Well, I have seen places where dynamite explosions have occurred, but I know of nothing to compare with this. I am sure that if dynamite has been used, or any explosive now generally obtainable, there would have been left, at least, some remnant of the safe. Hasn"t this pile of rubbish been disturbed since the explosion?"
"Yes, it has been turned over; we made a search for the two men, but we found no trace of them."
"And you found no particles of iron or steel?"
"The heap throughout is just as you see it on the surface--a fine, almost impalpable dust. We had to exercise the greatest care in searching through it, for the moment it was disturbed with a shovel it filled the air with suffocating clouds. Of course we shall have it removed by-and-by, and carted away, but I considered it better to allow it to remain here until we had penetrated somewhat further into the mystery than we have already done."
Jennie stooped and picked up a handful from the heap, her action caused a mist to rise in the air that made them both choke and cough, and yet she was instantly struck by the fact that her handful seemed inordinately heavy for its bulk.
"May I take some of this with me?" she asked.
"Of course," replied the Director. "I will have a packet of it put up for you."
"I would like to take it with me now," said Jennie. "I have curiosity to know exactly of what it is composed. Who is the Government a.n.a.lyst? or have you such an official?"
"Herr Feltz, in the Graubenstra.s.se, is a famous a.n.a.lytical chemist; you cannot do better than go to him."
"Do you think he knows anything about explosives?"
"I should suppose so, but if not, he will certainly be able to tell you who the best man is in that line."
The Director ordered one of the soldiers who accompanied him to find a small paper bag, and fill it with some dust from the treasure chamber.
When this was done, he handed the package to Jennie, who said, "I shall go at once and see Herr Feltz."
"My carriage is at your disposal, madame."
"Oh, no, thank you, I do not wish to trouble you further. I am very much obliged to you for devoting so much time to me already. I shall take a fiacre."
"My carriage is at the door," persisted the Director, "and I will instruct the driver to take you directly to the shop of Herr Feltz; then no time will be lost, and I think if I am with you, you will be more sure of attention from the chemist, who is a very busy man."
Jennie saw the Director did not wish to let her out of his sight, and although she smiled at his suspicion, she answered politely,--
"It is very kind of you to take so much trouble and devote so much of your time to me. I shall be glad of your company if you are quite certain I am not keeping you from something more important."
"There is nothing more important than the investigation we have on hand," replied the Chief grimly.
CHAPTER XV. JENNIE BESTOWS INFORMATION UPON THE CHIEF OF POLICE.
A few minutes after leaving the Treasury building the carriage of the Chief stopped in front of the shop of Herr Feltz in the wide Graubenstra.s.se. The great chemist himself waited upon them and conducted them to an inner and private room.
"I should be obliged to you if you would tell me the component parts of the mixture in this package," said Jennie, as she handed the filled paper bag to the chemist.
"How soon do you wish to know the result?" asked the man of chemicals.
"As soon as possible," replied Jennie.
"Could you give me until this hour to-morrow?"
"That will do very nicely," replied Jennie, looking up at the Director of Police, who nodded his head.
With that the two took their leave, and once more the Director of Police politely handed the girl into his carriage, and they drove to the Palace Steinheimer. Here she again thanked him cordially for his attentions during the day. The Director answered, with equal suavity, that his duty had on this occasion been a pleasure, and asked her permission to call at the same hour the next afternoon and take her to the chemist. To this Jennie a.s.sented, and cheerily bade him good-evening. The Princess was waiting for her, wild with curiosity to know what had happened.
"Oh, Jennie!" she cried, "who fired the mine, and who robbed the Government?"
Jennie laughed merrily as she replied,--
"Dear Princess, what a compliment you are paying me! Do you think that in one afternoon I am able to solve a mystery that has defied the combined talents of all the best detectives in Austria? I wish the Director of Police had such faith in me as you have."
"And hasn"t he, Jennie?"
"Indeed he has not. He watched me every moment he was with me, as if he feared I would disappear into thin air, as the treasure had done."
"The horrid man. I shall have my husband speak to him, and rid you of this annoyance."
"Oh, no, Princess, you mustn"t do anything of the kind. I don"t mind it in the least; in fact, it rather amuses me. One would think he had some suspicion that I stole the money myself."
"A single word from the Prince will stop all that, you know."
"Yes, I know. But I really want to help the Director; he is so utterly stupid."
"Now, Jennie, take off your hat and sit down here, and tell me every incident of the afternoon. Don"t you see I am just consumed with curiosity? I know you have discovered something. What is it?"
"I will not take off my hat, because I am going out again directly; but, if you love me, get me a cup of that delicious tea of yours."
"I shall order it at once, but dinner will be served shortly. You are surely not going out alone to-night?"
