Watson is an American television series created by Craig Sweeny which premiered on CBS on January 26, 2025. The series, described as a "medical drama with detective elements", is centered around the character of Dr. John Watson from Arthur Conan Doyle's Sherlock Holmes stories, with actor Morris Chestnut portraying the character. It is the second CBS series to adapt the Holmes stories, after Elementary. While the two programs are otherwise unrelated, their creative teams overlap.
One year after Sherlock Holmes's apparent death at the hands of his archenemy Moriarty in Reichenbach Falls, Dr. John Watson resumes his medical practice by opening the "Holmes Clinic" in Pittsburgh to treat patients with strange and unidentifiable issues. Soon however, Watson must face his past when evidence surfaces indicating that Moriarty is still alive.[1]
Morris Chestnut as John Watson, a physician and former London-based consulting detective who heads the Holmes Clinic in Pittsburgh, Pennsylvania. To aid his patients' cases, he applies a specific and incisive type of deductive reasoning that he learned from his years working with Sherlock Holmes.
Eve Harlow as Ingrid Derian, an aloof but highly skilled neurologist with an enigmatic past. She has a shaky relationship with her colleagues owing to her stony manner and questionable methods.
Peter Mark Kendall as Stephens Croft and Adam Croft, identical twin brothers, acting as infectious disease and functional medicine specialists at the clinic. Stephens, a Johns Hopkins graduate, is an emotionally withdrawn workaholic, while Adam, who attended Boston University, talks too much.
Inga Schlingmann as Sasha Lubbock, a specialist in rheumatology and immunology. She is torn between her birth parents from China and her adoptive family from Dallas.
Ritchie Coster as Shinwell Johnson, a former criminal from London and an acquaintance of Holmes and Watson who works as the clinic's administrative aide, his connections often proving very useful to the team.
Rochelle Aytes as Mary Morstan, a noted East Coast surgeon and Watson's ex-wife who serves as the clinic's medical director. Despite their divorce, she maintains a productive working relationship with Watson, acting as his voice of sanity and attempting to rein in his more irregular techniques.
Dr. John Watson suffers a traumatic brain injury during the final encounter between detective Sherlock Holmes and master criminal James Moriarty. Waking up in a Swiss hospital, Watson learns from Shinwell Johnson that Holmes secretly funded a private clinic in his will so Watson could find a new purpose in the event of his death. Several months later, Watson and his handpicked team take on a new patient at the request of his ex-wife, hospital administrator Mary Morstan. The patient, Erika Filipello, is seemingly dying from fatal insomnia, but using his investigative skills, Watson not only determines that she is suffering from a genetic deficiency of biotinidase but that her similarly ill cousin Autumn is actually the girl's half-sister. However, Autumn goes into septic shock, and Watson is unable to call in his usual surgeon due to adverse weather. Mary, a former surgeon, agrees to operate, saving Autumn's life. Watson later retrieves his old case files at Mary's encouragement. Shinwell delivers a case of genetic samples to a still-alive Moriarty, who reminds him that he is watching "always and everywhere."
