"Hello, who is it?"

The secret agent made reply; and the aide's voice, now containing an eager note, demanded:

"What's up?"

"Get O'Neill at once. It's too late for a train, but call Dixon to get out the car in a hurry. Then come to Morse's, Fordham Road, with all the speed you can."

"All right," replied Fuller. "I'll get Dixon first, and have O'Neill ready when the machine arrives."

Ashton-Kirk hung up, and then turned to Nanon, who stood but a few yards away, still nervously rubbing her hands with the corner of her apron.

"You saw no one but Miss Corbin a while ago?" he asked.

"No," answered the woman.

"You are sure of that?" His singular eyes searched her face, but she met the look without flinching.

"I am sure," she said. There was a silence; Ashton-Kirk then walked down the hall toward the library door; and as he reached it, he felt her hand touch his shoulder. "You did not see any one?" she asked.
