Is this a dagger which I see before me, The handle toward my hand?

It is the bloody business which informs
Thus to mine eyes. Now o’er the one halfworld
Nature seems dead, and wicked dreams abuse
The curtain’d sleep; witchcraft celebrates
Pale Hecate’s offerings, and wither’d murder,
Alarum’d by his sentinel, the wolf,
Whose howl’s his watch, thus with his stealthy pace.

With Tarquin’s ravishing strides, towards his design
Moves like a ghost. Thou sure and firm-set earth,
Hear not my steps, which way they walk, for fear
Thy very stones prate of my whereabout,
And take the present horror from the time,
Which now suits with it. Whiles I threat, he lives:

Words to the heat of deeds too cold breath gives.
