"You seem to be preoccupied, Mr. Daubeney. What has happened?" she inquired.
"I—I—really don't know."
His distress was so unmistakable that her quick woman's wit divined the true cause. They had now sauntered some distance away from the part of the tower that might be marked "dangerous," so she grasped Jimmy's ponderous arm, and whispered with a delightful smile—
"You saw me make signs to that Frenchman, didn't you?"
"Well—er—I—er——"
"Oh, yes, I understand. Of course you were surprised. But don't jump now, or say anything; he is my brother!"
She need not have warned Daubeney as to any remarks he might feel inclined to make, for her announcement again rendered him speechless.
"It is a mystery," she whispered, "a deep secret. We will tell you all about it at lunch."
