Person of Interest: Booked Solid

Reese and Finch have little to go on when Albanian hotel maid Mira Dobrica's number comes up on the Machine, so they go undercover as a bellboy and a concierge at the establishment. But they have their work cut out as there are more than 700 guests staying there, any one of whom could be their potential murderer - and that's not taking into account the other staff. Meanwhile, Moss invites Carter to become an FBI field agent and Hersh is on the lookout for Reese after escaping from Rikers Island
