Death of a Jaded Samurai - Diane Bator

The scroll of the Four Possessions of the Samurai holds the key to a deadly mystery...

Gilda Wright thinks she's landed a dream job as the receptionist at a karate school. Her boss, Sensei Mick Williams, is almost as demanding as he is sexy, but Gilda is inspired by the strength and courage of the people around her. When Gilda finds a body in the dojo with a sword through his chest, she must find her own inner strength and fast! The police regard her and everyone in the school as suspects and it's up to Gilda to find out what really happened. She follows the clues of the missing scroll of the Four Possessions of the Samurai down a deadly path filled with lies, deceit, and poisoned ninja stars.

If she doesn't watch her back, she just may become the killer's next target.
