By John Donne.

In which as in a gallery this mouse
Walk'd, and surveid the roomes of this vast house,
And to the braine, the soules bedchamber, went,
And gnaw'd the life cords there; Like a whole towne
Cleane undermined, the slaine beast tumbled downe;
With him the murtherer dies, whom envy sent
To kill, not scape, (for, only hee that ment
To die, did ever kill a man of better roome,)
And thus he made his foe, his prey, and tombe:
    Who cares not to turn back, may any whither come.
