The most exciting installment to the Edgar Award–winning samurai mystery series.
When a man with a tattoo covering his back is found floating in the water at a rice ceremony, Seikei and Judge Ooka know it's a bad omen. Soon there are seven of these men with partial tattoos on their backs. All different, all dead, all seemingly unrelated—except for the tattoos. It becomes apparent these men are not just carrying body art, but a treasure map . . . to what? And why is carrying this map so mortally dangerous? Seikei must find and assemble all seven tattoos to find the answer— and the path to a most terrifying destination.
