Titus Welliver Officially Returns as Bosch Today

Titus Welliver has spent more than a decade playing one of television’s most stubborn detectives, and while Bosch: Legacy brought his solo adventures to an end, it turns out Harry Bosch still has plenty of unfinished business. The actor has never hidden his desire to play the character for as long as possible, and although his days leading his own television series may be over, he’s found another way to return to the role. And this time, he’s bringing the actor who will play a younger version of Bosch along for the ride.

Welliver officially returns as Harry Bosch today, narrating the audiobook edition of The Hollow, the latest novel from bestselling author Michael Connelly. He’ll share narration duties with Cameron Monaghan (Shameless), who is also preparing to play a younger Bosch in MGM+’s upcoming prequel series, Bosch: Start of Watch. The new book takes the detective back to one of the darkest moments of his childhood, reopening a mystery that has haunted him for decades.

The story begins when Harry Bosch is 11 years old, and he becomes a ward of the state at the notorious MacLaren Children’s Center, where he was the victim of abuse. Decades later, a multibillion-dollar settlement for former residents has been negotiated, but when Bosch’s half-brother, defense attorney Mickey Haller, brings him the news that Harry is entitled to $400,000, Bosch says he doesn’t want the money. He wants justice.

News of the settlement awakens his memories of a place he had hoped never to revisit, and a boy named Chops, a fellow ward who wound up dead. Chops’s body was found in a hidden space under a staircase that the staff used to discipline their charges. The kids knew it only as “the hollow.” But Chops’s death was covered up and never solved. Now Bosch knows he must reopen the investigation and learn the truth, even if the killer is long dead.

Your answers have pointed to one action hero above all others. This is the person built to have your back — for better or considerably, spectacularly worse.

Your partner doesn’t talk much, doesn’t need to, and will have assessed every threat in your immediate environment before you’ve finished your first sentence. John Rambo is not a man of plans or politics — he is a force of nature shaped by survival, loyalty, and a capacity for endurance that goes beyond anything training can produce. He will not leave you behind. He has never left anyone behind who deserved to come home. What you get with Rambo is the most capable, most quietly ferocious partner imaginable — one who has been through things that would have broken anyone else, and who chose to keep going anyway. You’ll never need to ask if he has your back. You’ll just know.

Your partner will arrive perfectly dressed, perfectly briefed, and with a cover story so convincing it’ll take you a moment to remember what’s actually true. James Bond is the most professionally dangerous person in any room he enters — and the most disarmingly charming, which is the point. He operates in a world of layers, where nothing is what it appears and every advantage is used without apology. You’ll never be bored. You’ll occasionally be furious. But when it matters — when the mission is genuinely on the line and the margin for error has collapsed to nothing — Bond is exactly the partner you want. He has survived things that have no business being survivable. He does it with style. That is not nothing.

Your partner will know the history, the language, the cultural context, and exactly why the thing everyone else is ignoring is actually the most important thing in the room. Indiana Jones is brilliant, reckless, and occasionally impossible — but he is also one of the most resourceful, most genuinely knowledgeable partners you could find yourself beside. He approaches every situation with a scholar’s eye and a brawler’s instinct, which is an unusual combination and a remarkably effective one. He hates snakes and gets personally attached to objects of historical significance, both of which will slow you down at least once. It doesn’t matter. What Indy brings is irreplaceable — and the adventures you’ll have together will be the kind people write books about. Assuming you survive them.

Your partner was not supposed to be here. He does not have the right equipment, the right information, or anything approaching the right odds. He has a sarcastic remark and an absolute refusal to accept that the situation is as bad as it looks. John McClane is the greatest accidental hero in the history of action cinema — a man whose superpower is stubbornness, whose contingency plan is improvisation, and whose capacity to absorb punishment and keep moving would be alarming if it weren’t so useful. He will complain the entire time. He will make it significantly more chaotic than it needed to be. And he will absolutely, unconditionally, without question come through when it counts. Yippee-ki-yay.

Your partner has already run seventeen scenarios by the time you’ve finished reading the briefing, and the plan he’s settled on involves at least two things that should be physically impossible. Ethan Hunt operates at the absolute edge of human capability — technically, physically, and intellectually — and he brings the same relentless precision to protecting his partners that he brings to dismantling organisations that shouldn’t exist. He is not easy to know and he will never fully tell you everything. But he will carry the weight of the mission so completely, so absolutely, that your job is simply to trust him — and the remarkable thing is that trusting him always turns out to be the right call. The mission will be impossible. He will complete it anyway.

Titus Welliver and Cameron Monaghan Are Both Playing Harry Bosch

Welliver first played the detective in Bosch, which ran for seven seasons before continuing for another three in Bosch: Legacy. Although the latter concluded in 2025, Connelly’s crime universe has continued expanding through Prime Video’s Ballard, while the upcoming Start of Watch will explore Harry’s earliest days as a police officer. The prequel will star Monaghan as a young Bosch in 1991 Los Angeles, long before he became the experienced detective audiences know today. With the actor now joining Welliver on The Hollow audiobook, fans will get to hear both versions of the character in the same production.

The Hollow is available now. The UK hardcover edition follows on November 5. Listen to The Hollow and explore more Connelly novels with a free trial of Audible.
