“All right, all right,” I said hastily. “Why witchcraft? Who believes in witchcraft these days?”

Ansell looked at Bogle, satisfied himself that he was not going to have a fit and tried to collect his thoughts: “I don’t suppose you know much of the background of this country. I’ve lived here for over twenty years and I’ve seen some very odd things.”

“So have I,” Myra said, looking at Bogle.

“If you can’t stop this woman talking…” Ansell said to me furiously.

“Be good,” I said to Myra.

She lifted her shoulders.

“Go on,” I said. “Don’t worry about her.”

“If I’m to explain this at all,” Ansell said, rather hopelessly, “I wish you’d all listen. At one time there was a powerful secret society in this country who called themselves the Naguales. The members of this society were the witch doctors who bossed the Maya Indians. They are almost extinct now, but there’s a few of them who still practice in a little village not two hundred miles from here.”

“I’ve heard about ’em,” I said. “Aren’t they supposed to produce rain at a moment’s notice and change themselves into animals? You don’t believe that junk, do you?”

Ansell shook his head, “No, I don’t. I believe they have certain supernatural powers such as mass hypnotism, and in some rare cases they practice levitation, but that really doesn’t concern us. What I’m interested in is their herbal medicines. Have you ever heard of teopatli?”
