River

With his career and access to the Stevie case resting on the outcome of his psychiatric report, River must keep his unofficial investigations into Stevie's death to himself. This sends tensions high with his new partner Ira, who fears being dragged down by River's instability, and Chrissie, who needs River working on his own caseload, most pressingly investigating a suspicious workplace accident that has left a foreman fighting for his life.

But River's mind is elsewhere as the discovery that Stevie has been keeping secrets forces him to reassess how well he knew his best friend and colleague. Unearthing new information about who Stevie spoke with in the lead-up to her murder throws suspicion on somebody close to her - somebody with real motive.
