“Quick!” he cried. “We must get away from here.”

“Here! here!” said Hernandez calmly. “What is the matter? Give an account of yourself.”

“I was walking along the street,” said Von Blusen, “when I came across one of the Americans from aboard the Yucatan.”

“Who?” demanded Mrs. Sebastian anxiously.

“Young Stanley,” cried the captain.

“Stanley?” repeated the others.

“Yes. I heard someone following me, and I waited for him to come up. When I saw who it was I hit him with my fist and knocked him down. He was up in a moment, though, and pitched into me. We had quite a tussle, but I finally managed to get away and come here to warn you.”

“And were you followed?”

“I don’t know.”

“The Kaiser must be proud of you,” sneered Hernandez. “If you have botched his plans as you have ours, he would have you shot. Come,” he turned to the two women, “the game is up. We shall have to fly. If the Americano has followed this man here, my connection must soon be discovered. Consul Edwards will suspect. We must fly!”
