Yours by this hand: and to see how he prizes the foolish woman your wife! she gave it him, and he hath given it his whore.

– William Shakespeare

Othello, Act 4, Scene 1. Master manipulator Iago tells Othello that Desdemona gave her handkerchief to Cassio who in turn passed it to his prostitute girlfriend Bianca. We have a classic example of dramatic irony here, since the audience knows Iago is lying and placed the handkerchief in Cassio’s lodging to frame him.
