Book Log 2019 #36: Claws of the Cat by Susan Spann

When a samurai is killed in 16th century Kyoto, ninja Hiro Hattori is given three days to solve the crime, otherwise the geisha accused of the killing and Father Mateo, the Jesuit priest Hattori is sworn to protect, will be put to death. Hattori and Mateo delve into the samurai's life and find no shortage of suspects, though there seem to be even more people who want to thwart their investigation.

I liked this book quite a bit, both for the unusual setting for a murder mystery and the relationship between the ninja and the priest.  It reminds me vaguely of Brother Cadfael, though that may just be the religious aspects of the two series making a connection in my brain.
