Complete story — includes the ending
A night-time zoo caretaker and ESL (English Second Language) student is found dead in a pit of poisonous snakes. Castle, suffering from writer's block, convinces Beckett to let him help with the case. Castle goes undercover as an ESL student to get information from the other students, but it may not be easy understanding them, let alone getting them to talk. Meanwhile, Beckett's team finds that their victim may not be as innocent as he seems. Castle also remembers a little bit of where he was when he went missing.
