Have by the very cunning of the scene
Been struck so to the soul that presently
They have proclaimed their malefactions.
I’ll have these players
Play something like the murder of my father
Before mine uncle.
The play’s the thing
Wherein I’ll catch the conscience of the king.
II, 2, 617.
In hearing or reading this speech, the spectator or reader would naturally conclude that this was Hamlet’s first conception of the plot, in which he sought to prove by a mock performance of the murder the guilt or innocence of the king, yet a few minutes previously Hamlet had already conceived the idea of the play scene. Is this another sign of carelessness, or is Hamlet visualizing the effects of his scheme? Hunter, a Shakesperean commentator, would read “About ’t my brains,” that is, set about composing the lines which the players were to add to “The Murder of Gonzago,” he would also delete the word “hum.” By omitting the interjection he maintains that it makes prospective what is evidently retrospective. I contend that it does nothing of the sort, and the natural inference is, that the poet forgot that he had already invented the stratagem by which he intends catching the conscience of the king. Many instances occur in literature, whereas by means of a play representing a murder, the actual wrong-doer has confessed his crime, and been brought to justice. Such a scene is found in “A Warning to Fair Women,” a play acted by the Chamberlain’s company and printed in 1599. The play is founded on a celebrated murder case which took place in Lynn in Norfolk, in 1573.
