"Yes. And I went at once into the library. Upon his desk I found this, which was, more than likely, the cause of the outburst."
He handed Ashton-Kirk a sheet of paper; in the center was a cross, the only peculiarity of which was that the down stroke was red, and the other was blue. This the secret agent inspected with interest.
"I believe you said that he cried aloud in the library—did you catch any words?"
"No. But Miss Corbin did. She told me that——"
"Wait!" Ashton-Kirk halted him. "I would like to speak to Miss Corbin personally."
"Ah, yes. I suppose it would be best."
Warwick left the room. Instantly Ashton-Kirk was at the window, and after a glance, he laughed softly.
"Fuller," said he, "if you saw a man weeding a garden and another man clipping a hedge near by; and if you noticed that they gradually and almost imperceptibly worked toward each other, what should you think?"
Fuller looked out at the two stooping figures; the terrier had stopped his capering and lay gnawing one of the cuttings from the hedge, which he held between his paws.
"They are nearer to each other," said Fuller. "And look! they never exchange a glance. It seems to me," in the low, rapid tone of one to whom an idea had just occurred, "that they desire to speak to each other, but would rather not be observed."
