For an instant Rodney turns his eyes on her, and then goes back to his sneering examination of Geoffrey. Between them the two dogs still lie, quiet but eager.

"Call off the dogs," says Geoffrey to Mona, in a low tone; "there is no longer any necessity for them. And tell me how you come to be here, at this hour, with this—fellow."

Mona calls off the dogs. They rise unwillingly, and, walking into a distant corner, sit there, as though still awaiting a chance of taking some active part in the coming fray. After which Mona, in a few words, explains the situation to Geoffrey.

"You will give me an explanation at once," says Geoffrey, slowly, addressing his cousin. "What brought you here?"

"Curiosity, as I have already told Mrs. Rodney," returns he, lightly. "The window was open, the lamp burning. I walked in to see the old room."

"Who is your accomplice?" asks Geoffrey, still with studied calmness.

"You are pleased to talk conundrums," says Rodney, with a shrug. "I confess my self sufficiently dull to have never guessed one."

"I shall make myself plainer. What servant did you bribe to leave the window open for you at this hour?"

For a brief instant the Australian's eyes flash fire; then he lowers his lids, and laughs quite easily.

"You would turn a farce into a tragedy," he says, mockingly, "Why should I bribe a servant to let me see an old room by midnight?"
