The most successful, and therefore perhaps the greatest, criminal in Shakespeare is King Claudius of Denmark. His murder of his brother by pouring a deadly poison into his ear while sleeping, is so skilfully perpetrated as to leave no suspicion of foul play. But for a supernatural intervention, a contingency against which no murderer could be expected to have provided, the crime of Claudius would never have been discovered. Smiling, jovial, genial as M. Derues or Dr. Palmer, King Claudius might have gone down to his grave in peace as the bluff hearty man of action, while his introspective nephew would in all probability have ended his days in the cloister, regarded with amiable contempt by his bustling fellowmen. How Claudius got over the great difficulty of all poisoners, that of procuring the necessary poison without detection, we are not told; by what means he distilled the "juice of cursed hebenon"; how the strange appearance of the late King's body, which "an instant tetter" had barked about with "vile and loathsome crust," was explained to the multitude we are left to imagine. There is no real evidence to show that Queen Gertrude was her lover's accomplice in her husband's murder. If that had been so, she would no doubt have been of considerable assistance to Claudius in the preparation of the crime. But in the absence of more definite proof we must assume Claudius' murder of his brother to have been a solitary achievement, skilfully carried out by one whose genial good-fellowship and convivial habits gave the lie to any suggestion of criminality. Whatever may have been his inward feelings of remorse or self-reproach, Claudius masked them successfully from the eyes of all. Hamlet's instinctive dislike of his uncle was not shared by the members of the Danish court. The "witchcraft of his wit," his "traitorous gifts," were powerful aids to Claudius, not only in the seduction of his sister-in-law, but the perpetration of secret murder.
