Was ever book containing such vile matter
So fairly bound? O, that deceit should dwell
In such a gorgeous palace!

– William Shakespeare

Romeo and Juliet, Act 3, Scene 2. Metaphorically comparing Romeo to a "fairly bound" book and "gorgeous palace," Juliet laments that behind such a facade dwells "vile matter" and "deceit." After learning that Romeo killed her cousin Tybalt, Juliet is frustrated that Romeo can be so appealing on the outside, yet bad underneath. Deceit is personified in this passage.
