Strangely stirred, Myra undressed in the dark and crept into bed, but, tired though she was, it was a long time before she could compose herself to sleep.

"Am I falling in love with him?" she asked herself, and did not answer her own question.

She was inclined to laugh at herself next morning, and to chide herself for being sentimental, and the opportunity to administer another reproof speedily presented itself.

"Did you hear someone singing a serenade in the courtyard last night, Myra, after we went to bed?" one of the guests inquired in Don Carlos's hearing.

"Yes, I thought of throwing him a few coppers in the hope he would stop and let me get to sleep," drawled Myra, and had the satisfaction of seeing Don Carlos's lips tighten and his black brows draw together in a frown.

"If you are prepared to run the risk of being waylaid by El Diablo Cojuelo, I suggest that you go riding and allow me to show you the neighbourhood," Don Carlos said. "I have half a dozen good horses in my stables."

Myra, Tony, and several others who were keen on horse exercise welcomed the proposal with enthusiasm, and went to change into riding kit. Their ride was quite uneventful. They saw some fine mountain scenery, but no sign of any brigands. They did, however, meet a squad of mounted carabineros, who saluted them respectfully, and with the leader of whom Don Carlos paused to chat.

"You will be relieved to learn that the officer reports that everything seems quiet, and he has no news of El Diablo Cojuelo having been seen in the neighbourhood for many weeks," he reported when he rejoined his guests. "But I doubt if he has taken fright, as the Captain suggests. He isn't easily scared."

He made no attempt to make love to Myra that day, but often she caught him looking at her with an expression that baffled her and made her feel vaguely uneasy. He looked, somehow, like a schoolboy with a sphinx-like expression, planning mischief and inwardly enjoying some private joke.

"He is quite the most exasperating man I have ever met—and the most interesting," Myra reflected, as she dressed for dinner that evening. "I wonder if he really has a heart, or if he is acting all the time?"
