Sonnet 134 by Shakespeare

In Shakespeare's 134th sonnet, the speaker confronts the mistress after learning that she has seduced the Fair Youth.

Synopsis
In the first quatrain, the speaker confesses that both he and the friend are at the mistress's mercy; in the second one, he surmises that the attachment will hold, due to the friend's naivete and the mistress's greed.

The remainder of the poem construes the mistress as an unethical moneylender: metaphorically, she lent her beauty to the speaker and then collected the friend as interest.
