Meantime, in the captain's room the two men were quietly conversing.

"He wants you to sign a parole," said Carg.

"Not I."

"You may as well. I'm responsible for your safety."

"I deny anyone's right to be responsible for me. If you have made a promise to that effect, withdraw it," said the German.

"If I do, they'll put you in prison."

"Not at present. I am still an invalid. In reality. I am weak and suffering. Yet I am already planning my escape, and that is why I insist that you withdraw any promise you have made. Otherwise—"

"Otherwise?"

"Instead of escaping by water, as I had intended, to Ostend, I must go to the prison and escape from there. It will be more difficult. The water route is best."
