We're five weeks into Fox's dramatic thriller series and the epic battle between Ryan Hardy and psychotic serial killer Joe Carroll shows no signs of letting up any time soon. This week Claire and Hardy have a lead on the mad man's location, and his captors are terrified that they'll get caught up in a siege. As for the merciless man himself? Well, he's got other things in mind, contacting his former lawyer and asking her to deliver a particularly deadly message. And no, we're not talking 'deadly buzz'.
