Lover's Cross

After a bad car accident, Jory's lover Peter assures him he's doing fine. But when Jory attends a get-well party at the house of a coworker, he's surprised when no one asks him how Peter is doing. More disconcerting, Peter's gold cross necklace is missing, and Jory suffers from headaches whenever his best friend Bruce brings up the accident.

Where is the cross? And why does Bruce keep asking Jory to remember what happened to his lover?
