“But what about these men that the Sheikh is taking with us? They will be in the secret.”
“Of course.”
“Suppose they betray what I am.”
“That would mean betraying their Sheikh. You need have no fear of that.”
“Well, let’s talk about something else. We are bound now for the Sheikh’s encampment. What is going to be done first when we get there?”
“We put off Europe and put on Africa as far as is necessary.”
“Hah!” said Frank, with a sigh.
“What does that mean, my lad?” said the professor sternly. “Are you beginning to repent?”
“Repent!” said Frank between his teeth. “What a question! I am longing to commence, for so far everything has been preparation.”
