Lone Wolf and Cub: Perhaps in Death (Lone Wolf and Cub #25)

The mortal enemy of our ronin hero, Retsudo Yagyu has been imprisoned in Edo castle by the shogun. It seems the conniving poisoner, Abeno Kaii, has exposed the Yagyu letter! And Yagyu's jailer is none other than the poisoner himself, determined to feed Retsudo the dose that will end his life in a pit of dishonor. But Yagu has spies even in Edo caslte, and a message is sent to his "grass," members of the clan hiding in secret, living as normal townspeople throughout Japan. It is up to them to give their lives in this final hour of desperate need. Meanwhile, Itto Ogami is living in a shack and training his little boy for the day when he must protect the battlefield with his own little hands. Still, two swords remain in this field of death, awaiting the two hands that will draw them from the soil and bring us closer to the end of our tale.
