At least it seemed so to Essex; and, abandoning all plans for again enjoying the favor of Elizabeth, he began to consider what he could do to undermine her power and rise upon the ruins of it. The idea was insanity, but passion always makes men insane. James, king of Scotland, the son and successor of Mary, was the rightful heir to the English throne after Elizabeth's death. In order to make his right of succession more secure, he had wished to have Elizabeth acknowledge it; but she, always dreading terribly the thoughts of death, could never bear to think of a successor, and seemed to hate every one who entertained any expectation of following her. Essex suppressed all outward expressions of violence and anger; became thoughtful, moody, and sullen; held secret consultations with desperate intriguers, and finally formed a scheme to organize a rebellion, to bring King James's troops to England to support it, to take possession of the Tower and of the strong-holds about London, to seize the palace of the queen, overturn her government, and compel her both to acknowledge James's right to the succession and to restore Essex himself to power. The personal character of Essex had given him a very wide-spread popularity and influence, and he had, consequently, very extensive materials at his command for organizing a powerful conspiracy. The plot was gradually matured, extending itself, in the course of the few following months, not only throughout England, but also into France and Spain. The time for the final explosion was drawing near, when, as usual in such cases, intelligence of the existence of this treason, in the form of vague rumors, reached the queen. One day, when the leading conspirators were assembled at Essex's palace, a messenger came to summon the earl to appear before the council. They received, also, private intelligence that their plots were probably discovered. While they were considering what to do in this emergency--all in a state of great perplexity and fear--a person came, pretending to be a deputy sent from some of the principal citizens of London, to say to Essex that they were ready to espouse his cause. Essex immediately became urgent to commence the insurrection at once. Some of his friends, on the other hand, were in favor of abandoning the enterprise, and flying from the country; but Essex said he had rather be shot at the head of his bands, than to wander all his days beyond the seas, a fugitive and a vagabond.
