"I'm sorry," she remarked merely, "but I'm afraid my control is weak and cannot work today."
She took a step toward the door, motioning us to leave. Neither of us paid any attention to that hint, but remained seated as we had been before.
"Go!" she exclaimed at length, for the first time showing a trace of nervousness.
Evidently her suspicions had been fully confirmed by our actions. We tried to argue with her to gain time. But it was of no use.
Almost before I knew what she was doing, she made a dash for something in the corner of the room. It was time for open action, and I seized her quickly.
My detective was on his feet in an instant.
"I'll take care of her," he ground out, seizing her wrists in his vice-like grasp. "You give the signal."
I rushed to the window, threw up the shade and opened the sash, waving our preconcerted sign, turning again toward the room.
With a sudden accession of desperate strength, Savetsky broke away from the plainclothesman and again attempted to get at something concealed on the wall. I had turned just in time to fling myself between her and whatever object she had in mind.
As the detective took her again and twisted her arm until she cried out in pain, I hastily investigated the wall. She had evidently been attempting to press a button that rang a concealed bell.
