How does Clark defuse a situation between a husband and wife on November 22nd according to The Journals of Lewis and Clark?

On November 22nd, William Clark learns from an interpreter that a man living near the construction site is about to kill his wife. He goes to meet the husband, who says he is convinced his wife slept with one of Clark's officers. Clark argues that no one is allowed to kill anyone around the Fort, and he does not believe that anyone of his party would touch his wife because such behavior is strictly forbidden.
