Master ninja Hiro Hattori and Jesuit Father Mateo head up to Mount Koya,
only to find themselves embroiled in yet another mystery, this time in a
Shingon Buddhist temple atop one of Japan's most sacred peaks. November,
1565: Master ninja Hiro Hattori and Portuguese Jesuit Father Mateo
travel to a Buddhist temple at the summit of Mount Koya, carrying a
secret message for an Iga spy posing as a priest on the sacred mountain.
When a snowstorm strikes the peak, a killer begins murdering the
temple's priests and posing them as Buddhist judges of the
afterlife--the Kings of Hell. Hiro and Father Mateo must unravel the
mystery before the remaining priests--including Father Mateo--become
unwilling members of the killer's grisly council of the dead.
