One night in a rage he nearly beats her to death and Jill is forced to fire her rifle through a closed door to keep him from breaking into the house. He disappears–did Jill kill him? Detective-Inspector Napoleon Bonaparte is badly hampered in this case by terrifying floods, but he solves his case as usual.
