Sonja has a knife in her boot

"Damn you to—the hells!" She half-crouched, pulled her knife from its sheath in her boot, lifted her arm to fling—

Then someone gripped her wrist strongly, and stopped her. Sonja growled and twisted about-looked into Daron's eyes.

"Useless," he said in a low voice. "Give it to me."

Perplexed, Sonja nodded. Daron took the knife from her, then carefully advanced the last few steps towards the sorcerer at the end of the corridor.
