David E. Kelley is moving deeper into Michael Connelly’s crime universe with a new HBO Max detective drama built around Nightshade, the author’s 2025 novel introducing Los Angeles County Sheriff’s Detective Stilwell on Catalina Island.
The project, titled Welcome to Catalina, is in development at HBO Max, with Kelley writing and executive producing. It marks another television collaboration between one of American television’s most prolific drama writers and one of crime fiction’s most commercially durable authors, at a time when streaming platforms are sharpening their focus on procedurals with recognisable literary foundations and repeatable season structures.
The drama centres on Detective Stilwell, a Los Angeles County Sheriff’s investigator reassigned to Catalina Island after clashing with department politics on the mainland. What appears to be a quieter posting soon turns into a murder inquiry after a body is found in the island’s harbour, pulling the character into a case that exposes tensions beneath Catalina’s tourist-facing calm.
The series is being developed as HBO Max looks to expand the kind of efficient, character-led procedural drama that helped The Pitt stand out in the streaming market. That model leans on experienced showrunners, longer episode orders than many prestige-streaming dramas, controlled budgets and a release pattern designed to build habit rather than deliver only a brief binge-window surge.
For Kelley, the project extends a long record of adapting books into polished television dramas. His credits include Big Little Lies, The Undoing, Presumed Innocent, Anatomy of a Scandal, Nine Perfect Strangers and The Lincoln Lawyer. His work has often combined legal, domestic or criminal suspense with strong ensemble casting, making him a natural fit for Connelly’s character-driven procedural storytelling.
The timing is notable because The Lincoln Lawyer, the Netflix legal drama based on Connelly’s Mickey Haller novels, is heading towards its fifth and final season. The series, starring Manuel Garcia-Rulfo, has been one of Netflix’s reliable scripted performers and is set to close with an adaptation of Resurrection Walk. Kelley created the television version, while Ted Humphrey and Dailyn Rodriguez have steered the show as co-showrunners.
Welcome to Catalina* gives Kelley and Connelly a way to keep a new crime protagonist moving through the television pipeline without relying on the already crowded Bosch-Haller orbit. Stilwell is designed as a fresh lead, separate from Harry Bosch, Mickey Haller and Renée Ballard, while still carrying the familiar Connelly themes of institutional pressure, moral persistence and the cost of pursuing a case when superiors would prefer it closed.
Connelly’s television footprint has expanded steadily over the past decade. Bosch helped establish Amazon’s crime-drama credentials, while Bosch: Legacy carried the character into a later phase. Ballard, built around LAPD detective Renée Ballard, widened the screen universe further. The Lincoln Lawyer gave Netflix a courtroom-centred counterpart with a more mainstream legal-drama rhythm. A Catalina-set series would add a more contained island procedural, allowing the setting itself to become a pressure chamber.
The source novel gives the adaptation a strong visual and structural hook. Catalina Island, often associated with leisure, tourism and seclusion, becomes a jurisdiction where law enforcement resources are limited, mainland bureaucracy remains close enough to interfere, and the geography can intensify both suspicion and isolation. That setting offers HBO Max a drama that can balance case-of-the-week appeal with longer arcs around Stilwell’s past, departmental rivalries and the island’s buried secrets.
No casting has been announced, and HBO Max has not set a release date. The development stage also means the project has not yet received a formal series order. Its progress will depend on scripting, network approvals, production planning and the streamer’s broader drama slate. Still, the combination of Kelley, Connelly and a new lead detective gives the project a stronger foundation than many early-stage crime dramas competing for attention.
The show also arrives as streamers reassess the economics of scripted television. The expensive limited-series boom has given way to renewed interest in procedurals, legal dramas, medical shows and police stories that can sustain multiple seasons, travel internationally and remain accessible to viewers who do not follow every episode immediately. Connelly’s brand fits that shift because his novels are plot-driven but character-centred, with a readership already familiar with his style of moral ambiguity and investigative momentum.
Kelley’s involvement points to a version of Nightshade that is likely to prioritise pace, dialogue and conflicts inside institutions rather than rely solely on the murder mystery. His best-known adaptations have often worked by pushing professional systems — courts, schools, marriages, police departments and elite communities — until private compromises become public crises.
