Doc Hand and Greyson left directly after luncheon. Benson packed the basket which some of the boys would take back to the ranch before he rode off to Upper Farm on an errand for Courtlandt. Steve helped Jerry mount and swung into the saddle. The girl tightened her rein then held up an arresting finger.

"Listen! The Kreutzer Sonata," she whispered.

From somewhere up-stream came the notes of a violin. There was a rare brightness, an aerial quality to the music that most artists take too gravely. The variations of the slow movements gave the sense of a glorified voice. Jerry drew a long, tremulous breath as the last note died away.

"That must have been the Man of Mystery," she confided in a low voice, as though fearful even at that distance of disturbing the musician. "I don't care if he did drop from the sky, if he never receives letters, he plays like—like an angel—if angels can play," with a laugh. Courtlandt looked up-stream as though mystified.

"I knew a man who played that sonata, just like that, but—but it can't possibly be he. Who did you say you thought it was?"

"Bill Small, the range-rider at the B C. Mrs. Carey told me about him when I called there yesterday. She said that the boys of the Double O and X Y Z outfits trailed over there every chance they could get to hear him play. That reminds me," her beautiful face glowed with enthusiasm, "I—I wonder if—if the boys of our outfit would care to have me play and sing for them? I should so love to do it."

"Care! I know they would. Pete says that they line up outside the court wall after dinner on the chance of hearing you sing."

"Really—really, Steve? I'd rather have that tribute than—than my name in electric lights on the Great White Way. Ask them up this afternoon. We'll have an honest-to-goodness musicale with Signora Geraldina Courtlandta as head-liner. Hurry!" She touched her horse with her heels. "It's a pity that Bruce Greyson didn't wait. He——"

"Your proposition was to sing for the Double O outfit. Greyson doesn't come in on that."

"Ogre! I can hear my bones scrunch between those strong white teeth of yours when you look at me like that."
