A spy may flatter to the vanity of a seditious minister's son, of gentle manners and dignified conduct by telling him "Though thou art the king's son, thou art kept here in fear of enemies." The king may secretly honour this deluded person and tell him that "apprehending danger from the minister, I have put off thy installation, though thou hast attained the age of heir apparent." Then the spy may instigate him to murder the minister. The task being accomplished, he, too, may be put to death in the same spot under the plea that he is a parricide.
