Part 4 (1/2)

The envelope was empty. We looked at each other a moment in silence.

What had been done with the plans?

Suddenly a bell rang, startling me beyond measure. It was, however, only the telephone, of which an extension reached up into the attic-a.r.s.enal. Some one, who did not know that we were there, was evidently calling up.

Kennedy quickly unhooked the receiver with a hasty motion to me to be silent.

”h.e.l.lo,” I heard him answer. ”Yes, this is it.”

He had disguised his voice. I waited anxiously and watched his face to gather what response he received.

”The deuce!” he exclaimed, with his hand over the transmitter so that his voice would not be heard at the other end of the line.

”What's the matter?” I asked eagerly.

”It was Mrs. Annenberg--I am sure. But she was too keen for me. She caught on. There must be some pa.s.sword or form of expression that they use, which we don't know, for she hung up the receiver almost as soon as she heard me.”

Kennedy waited a minute or so. Then he whistled into the transmitter.

It was done apparently to see whether there was anyone listening. But there was no answer.

”Operator, operator!” he called insistently, moving the hook up and down. ”Yes, operator. Can you tell me what number that was which just called?”

He waited impatiently.

”Bleecker--7l80,” he repeated after the girl. ”Thank you. Information, please.”

Again we waited, as Craig tried to trace the call up.

”What is the street address of Bleecker, 7180?” he asked. ”Five hundred and one East Fifth--a tenement. Thank you.”

”A tenement?” I repeated blankly.

”Yes,” he cried, now for the first time excited. ”Don't you begin to see the scheme? I'll wager that Baron Kreiger has been lured to New York to purchase the electro-magnetic gun which they have stolen from Fortescue and the British. That is the bait that is held out to him by the woman. Call up Miss Lowe at the laboratory and see if she knows the place.”

I gave central the number, while he fell to at the little secret drawer of the desk again. The grinding of the wheels of a pa.s.sing trolley interfered somewhat with giving the number and I had to wait a moment.

”Ah--Walter--here's the list!” almost shouted Kennedy, as he broke open a black-j.a.panned dispatch box in the desk.

I bent over it, as far as the slack of the telephone wire of the receiver at my ear would permit. Annenberg had worked with amazing care and neatness on the list, even going so far as to draw at the top, in black, a death's head. The rest of it was elaborately prepared in flaming red ink.

Craig gasped to observe the list of world-famous men marked for destruction in London, Paris, Berlin, Rome, Vienna, St. Petersburg, and even in New York and Was.h.i.+ngton.

”What is the date set?” I asked, still with my ear glued to the receiver.

”To-night and to-morrow,” he replied, stuffing the fateful sheet into his pocket.

Rummaging about in the drawer of the table, I had come to a package of gold-tipped cigarettes which had interested me and I had left them out.

Kennedy was now looking at them curiously.

”What is to be the method, do you suppose?” I asked.
