Daoud's body stiffened with rage. Celino's words were a blow that tore open an old wound.
"You know nothing of that, and for your own safety you had best not speak of it to me," Daoud said in a choked whisper.
Celino inclined his head. "I ask your forgiveness."
"Remember that if we fail in this mission, it will mean great harm to your King Manfred, who has been so good to you and raised you so high," Daoud said.
Celino's head was still lowered in submission. "You are right to remind me of that. I have been foolish."
Daoud gripped Celino's wrist. The Sicilian raised his head and stared into Daoud's eyes.
Daoud said, "I must have your oath that this will never happen again. Should you see a hundred Jews having their throats cut, you will smile like a good Christian and declare the sight pleasing to God."
"I will do my best, Daoud. That is all I can honestly promise you, but I think it will be good enough."
By being honest, as he puts it, he still leaves himself room to defy me.
"And you will obey my commands from now on, as if they came from your king?"
