4. Controlling Interest

Complete story — includes the ending

The now-destitute Mozzie has moved into Neal's apartment. With the investigation of Siegel's death stalled, Peter joins Neal for a new field assignment. A disoriented man named Nate Griffith ( David Call ) walks into the Bureau, carrying a packet of cash, confessing that he broke into a vault and stole $2 million. Peter and Neal trace Griffith to Dr. Mara Summers, his psychiatrist. Peter decides to examine the vault with Neal. The bank claims ignorance of any break-in. Neal checks their records for details on the vault, and traces it back to "Niteowl Holdings". Peter and Neal suspect Dr. Summers has something to do with the robbery. Peter traces Niteowl Holdings to Shane Jacobi, an ex-con, and confronts him. He denies any connection to Niteowl Holdings, but appears surprised to learn that the vault was robbed. Meanwhile, Neal approaches Dr. Summers as a patient, hoping to glean some information from her. But she drugs him, and gets information on the ongoing investigation from him. Moz identifies the drug as "Good Night Cinderella", used by Asian prostitutes to rob their johns. He suggests that the best way to recall what he told Dr. Summers would be to go back under the drug again. Moz makes the drug, Neal drinks it, and Peter and Moz help Neal recall the entire conversation. The next day, Peter and Jones visit Griffith's house, and on discovering Jacobi there, they arrest him. They realize that Summers manipulated Griffith into robbing Jacobi's vault. Neal gets a confession from Dr. Summers by putting her under the drug. The FBI arrest Dr. Summers but do not recover the money, because Neal has diverted it and given it to Mozzie to start afresh. He tells Mozzie that he plans to free himself from all constraints, including both Hagan's and Peter's.
