'Professor T' Season 4: Just 12 Days to Go — Can He Outdo Himself Again?
And I’m already bracing for the chaos ahead.
I’ve been keeping tabs on Professor T Season 4 since ITV dropped that first teaser, and now the release dates are finally clear. If you’re in the United States, mark your calendar for Sunday, August 24, 2025 at 8:00 PM ET on PBS.
PBS Passport members, though, get the real win — all six episodes drop early on August 10, 2025.
If you’re in the United Kingdom, you’re ahead of us. ITV1 aired Season 4 starting March 27, 2025, at 9:00 PM, with every episode ready to stream on ITVX and STV Player.
What’s New in Professor T Season 4
I went into Professor T Season 4 expecting more clever cases, but from what I’ve seen in early previews, it’s sharper than I imagined. The story reportedly picks up six months after Season 3’s ending, with a wave of crimes hitting Cambridge University.
Ben Miller’s Professor T is still brilliant and impossible, and early episode synopses suggest personal storylines push to the front — his mother Adelaide’s romantic life takes an unexpected turn, and Dr. Helena Goldberg finds herself mixing her professional role with personal feelings.
The Future of Professor T
It’s official — Professor T isn’t stopping here. ITV confirmed a Season 5, and if Season 4 is any hint, it’s going to lean even harder into layered mysteries and evolving character arcs. No vague teases here — they’re already planning more complex Cambridge cases.
