Let the devil and his dam haunt you! What did you mean by that same handkerchief you gave me even now? I was a fine fool to take it. I must take out the work? – A likely piece of work, that you should find it in your chamber, and not know who left it there!

– William Shakespeare

Othello, Act 4, Scene 1. Bianca enters with the handkerchief in hand that Cassio told her he found in his chamber and asked her to copy. In an outburst of jealousy, she curses him and doesn’t believe his story of how he came by the handkerchief. Neither she nor Cassio are aware that this is Desdemona’s handkerchief.
