Cunning leads to knavery. It is but a step from one to the other, and that very slippery. Only lying makes the difference; add that to cunning, and it is knavery.
We beg one hour of death, that neither she
With widow's tears may live to bury me,
Nor weeping I, with wither'd arms, may bear
My breathless Baucis to the sepulchre.
