Blood asketh blood, and death must death requite:
Jove, by his just and everlasting doom,
Justly hath ever so requited it.

_Act V, Scene 1._--This warning is proved true by a report of the death
of the king and queen at the hands of their subjects in revolt against
the blood-stained House. Certain of the nobles, gathered together,
resolve upon an alliance for the purpose of restoring a strong
government. The Duke of Albany, however, thinks to snatch power to
himself from this opportunity. _Scene 2._--Report is made of the
suppression of the rebellion, but this news is immediately followed by a
report of Albany's attempted usurpation of the throne. Coalition for his
defeat is agreed upon, and the play ends with the mournful soliloquy of
that aged counsellor who first opposed the division of the throne and
now sees, as the consequence of that fatal act, his country, torn to
pieces by civil strife, left an easy prize for an ambitious conqueror.

Hereto it comes when kings will not consent
To grave advice, but follow wilful will.
This is the end, when in fond princes' hearts
Flattery prevails, and sage rede[51] hath no place:
These are the plagues, when murder is the mean
To make new heirs unto the royal crown....
And this doth grow, when lo, unto the prince,
Whom death or sudden hap of life bereaves,
No certain heir remains, such certain heir,
As not all only is the rightful heir,
But to the realm is so made known to be;
And troth thereby vested in subjects' hearts,
