While Florence busied herself with writing the letter to her father, Jo Ann kept up a steady chatter about the mystery of the blue-eyed boy. “I’d certainly like to find out more about that man that María kept calling the ‘mean man.’ What reason could he have had for having been so hateful to Carlitos’ mother? From what María said everybody else liked her. Another thing I want to know is why his father disappeared so suddenly and where he went. A mystery within a mystery.”

Peggy smiled. “You ought to be satisfied this time, Jo. It’ll keep you busy for a long time if you untangle all this mix-up.”

About a half hour later, Jo Ann caught sight of a man with a big sombrero riding a burro leisurely up the cart road toward the house.

“Somebody’s coming,” she called to Florence. “Is it the man that brings the mail?”

Florence came running out on the porch. “Yes—that’s the one. He’s bringing us some groceries, too.”

“Let’s run down and meet him. I can’t wait to see if I have any letters.”

The three girls tore off down the road.

“Got any mail for us?” Florence asked on nearing the rider.

The man nodded his head. “Ah, many letters!”
