"Yes," murmured Dolores. "It's Forsetta and the Mazzani brothers." But, when Simon proposed to go after them, "No!" she said, without concealing her repugnance. "They're a bad lot. There's nothing to be gained by joining them."

But he was not listening; and, as soon as they were within hearing, he shouted:

"Is Antonio anywhere about?"

The three men set down their bundles, while Simon and Dolores dismounted and Forsetta, who had a revolver in his hand, thrust it into his pocket. He was a great giant of a fellow.

"Ah, so it's you, Dolores?" he said, after saluting Simon. "Faith, no, Antonio's nowhere hereabouts. We've not seen him."

He smiled with a wry mouth and treacherous eyes.

"That means," retorted Simon, pointing to their burdens, "that you and Mazzani thought it simpler to go hunting in this direction?"

"May be," he said, with a leer.

"But the old professor? Antonio left him in your charge."
