hibition, rose uncertainly to his feet.

Jennie sprang up and said menacingly, "Stay where you are!"

"I am not going to touch you. If you are so suspicious of every move
I make, then go yourself and bring me what I want. There is a map of
Vienna pinned against the wall yonder. Bring it to me."

Jennie proceeded in the direction indicated. It was an ordinary map of
the city of Vienna, and as Jennie took it down she noticed that across
the southern part of the city a semi-circular line in pencil had been
drawn. Examining it more closely, she saw that the stationary part of
the compass had been placed on the spot where stood the building which
contained the Professor's studio. She paid closer attention to the
pencil mark and observed that it passed through the Treasury building.

"Don't look at that map!" shrieked the Professor, beating the air with
his hands. "I asked you to bring it to me. Can't you do a simple action
like that without spying about?"

Jennie rapidly unfastened the paper from the wall and brought it to him.
The scientist scrutinized it closely, adjusting his glasses the better
to see, then deliberately tore the map into fragments, numerous and
minute. He rose--and this time Jennie made no protest--went to the
window, opened it, and flung the fluttering bits of paper out into the
air, the strong wind carrying them far over the roofs of Vienna. Closing
the casement, he came back to his chair.

"Was--was anyone hurt at this explosion?" he asked presently.

"Yes, four men were killed instantly, a dozen were seriously injured and
are now in hospital."

"Oh, my God--my God!" cried the old man, covering his face with his
hands, swaying from side to side in his chair like a man tortured with
agony and remorse. At last he lifted a face that had grown more pinched
and yellow within the last few minutes.

"I can tell you nothing," he said, moistening his parched lips.

"You mean that you _will_ tell me nothing, for I see plainly that you
know everything."

"I knew nothing of any explosion until you spoke of it. What have I to
do with the Treasury or the Government?"

"That is just what I want to know."

"It is absurd. I am no conspirator, but a man of learning."

"Then you have nothing to fear, Herr Seigfried. If you are innocent, why
are you so loth to give me any assistance in this matter?"

"It has nothing to do with me. I am a scientist--I am a scientist. All
I wish is to be left alone with my
