When Danyémon saw that he had not only been cheated into giving up the old woman, but was being made a laughing-stock of into the bargain, he flew into a great rage, and thought to break into the house and seize Matagorô and his mother by force; but, peeping into the courtyard, he saw that it was filled with Hatamotos, carrying guns and naked swords. Not caring then to die fighting a hopeless battle, and at the same time feeling that, after having been so cheated, he would be put to shame before his lord, Sasawo Danyémon went to the burial-place of his ancestors, and disembowelled himself in front of their graves.
When the Prince heard how his messenger had been treated, he was indignant, and summoning his councillors resolved, although he was suffering from sickness, to collect his retainers and attack Abé Shirogorô; and the other chief Daimios, when the matter became publicly known, took up the cause, and determined that the Hatamotos must be chastised for their insolence. On their side, the Hatamotos put forth all their efforts to resist the Daimios. So Yedo became disturbed, and the riotous state of the city caused great anxiety to the Government, who took counsel together how they might restore peace. As the Hatamotos were directly under the orders of the Shogun, it was no difficult matter to put them down: the hard question to solve was how to put a restraint upon the great Daimios. However, one of the Gorôjin,[17] named Matsudaira Idzu no Kami, a man of great intelligence, hit upon a plan by which he might secure this end.
There was at this time in the service of the Shogun a physician, named Nakarai Tsusen, who was in the habit of frequenting the palace of my Lord Kunaishôyu, and who for some time past had been treating him for the disease from which he was suffering. Idzu no Kami sent secretly for this physician, and, summoning him to his private room, engaged him in conversation, in the midst of which he suddenly dropped his voice and said to him in a whisper—
"Listen, Tsusen. You have received great favours at the hands of the Shogun. The Government is now sorely straitened: are you willing to carry your loyalty so far as to lay down your life on its behalf?"
"Ay, my lord; for generations my forefathers have held their property by the grace of the Shogun. I am willing this night to lay down my life for my Prince, as a faithful vassal should."
"Well, then, I will tell you. The great Daimios and the Hatamotos have fallen out about this affair of Matagorô, and lately it has seemed as if they meant to come to blows. The country will be agitated, and the farmers and townsfolk suffer great misery, if we cannot quell the tumult. The Hatamotos will be easily kept under, but it will be no light task to pacify the great Daimios. If you are willing to lay down your life in carrying out a stratagem of mine, peace will be restored to the country; but your loyalty will be your death."
"I am ready to sacrifice my life in this service."
"This is my plan. You have been attending my Lord Kunaishôyu in his sickness; to-morrow you must go to see him, and put poison in his physic. If we can kill him, the agitation will cease. This is the service which I ask of you."
