Murder in the Dojo: The Black Belt Mystery Series

Nell Letterly’s dream job as a karate instructor involves a few little first-day glitches. She finds the guy she replaced very dead–killed with her martial arts weapons. The police don’t bother to investigate anybody else. Her boss suddenly disappears. The dojo is a dump and the students know nothing. Plus, she faces foreclosure on her house, and her teen-age daughter hates her. Line the students up and look positive. After work, find the killer before the killer finds her.
