Masashi: An Ennin Mystery #68 by Ben Stevens is a quick story to read.
Mashasi was Japan's legendary swordsman. He was a bully with a sword who achieved a name by killing lesser men.
This short story has multiple layers. The end was a pleasant surprise. I gave it four stars.
I received a complimentary copy in an Amazon promotion. That did not change my opinion for this review.
