Also, when Captain Gregson resumes leadership of the precinct, he suspects his interim replacement, Captain Dwyer, is responsible for one of his best detective's suspicious departure.
In the bullpen at the 11th Precinct, Captain Dwyer welcomes Captain Gregson back to duty in front of his command. In Gregson's office, Detective Bree Novacek tells Gregson that she's leaving the NYPD. Gregson is concerned given Novacek's excellent record and that she's close to her pension. Ridley Dineen returns to his apartment with a bag full of cash and calls his girlfriend Janice over to celebrate. Janice arrives and finds a trail of cash leading to Ridley's bedroom. She finds him dead, laying half-naked in bed on top of many bills. At the Morgue while viewing Dineen's body, Detective Bell tells Holmes and Watson that Dineen robbed other criminals. Dr. Hawes notes Dineen died of an overdose, which he believes was fentanyl. Bell and Holmes argue whether Dineen was poisoned by touching fentanyl-laced cash while Bell reports that blood was found on Dineen's gun.
