Complete story — includes the ending
Peter is offered a promotion and reassignment to DC, but he is reluctant to take it until he resolves the mystery of Siegel's murder. Neal brings the panel to a meeting with Hagan intending to bargain, but Hagan shows him that he is holding Rebecca hostage and forces him and Mozzie to solve the puzzle hidden in the Codex. Peter is called to investigate an apparent forgery of a painting by William Blake. He calls in Neal despite the tension between them, and Neal finds Hagan's hidden signature in the painting. By offering to buy the painting and then tracking the resulting computer activity, Peter finds the seller's location, which is the very building where Neal and Mozzie are working with Hagan. Neal forces Hagan to release Rebecca by threatening to destroy the Codex chapter, then does it anyway after Mozzie has memorized their results. He finds Rebecca on a Brooklyn street and they embrace; Rebecca tells Neal that the hidden treasure is a twin to the Hope Diamond. The FBI arrive at that building and arrest Hagan, who says he has information that Peter should consider if he values his freedom. They go to Hagan's house to look at it, but Hagan is killed by a sniper before he can reveal anything. On Hagan's body is information that leads Neal and Peter to a Brooklyn apartment, which both Hagan and Siegel were watching on the day Siegel died. They enter the apartment and find three things: extensive files on Neal, Peter, and their associates, preparations to make both the Blake forgery and Hagan's signature, and evidence that the apartment's occupant is actually Rebecca.
