THE MARLOW MURDER CLUB: Season 3 News

Mark your calendars! The Marlow Murder Club returns to MASTERPIECE Mystery! for Season 3 on Sunday, Sept. 6, 2026, on MASTERPIECE on PBS. In Season 3, Judith Potts (Samantha Bond), Suzie Harris (Jo Martin), Becks Starling (Cara Horgan), and DI Tanika Malik (Natalie Dew) all return to solve a string of high-profile murders including that of the mayor and a popular chef. Seasons 1 & 2 of the series are available to stream via PBS and PBS MASTERPIECE on Prime Video.

I've watched the first two episodes, and they're terrific. I love this series, and the first two episodes (one story) involve a poison garden. Well, that's right up my alley. As many of you know I have a great garden, divided into individual patches. Although I used to have a designated poison garden, I now have only some poisonous plants incorporated into my other garden plots.  Still, I loved seeing a dedicated poison garden, replete with signage. So beautiful--and deadly. And, not a secret, but fun was the guest appearance of Peter Davidson. Such fun! Everything about The Marlow Murder Club appeals to me--the acting, the setting, the house, the river, the gardens. Mark your calendar for September 6!

Season 3: Returning to solve more complex and intriguing murders in Marlow are meticulous crossword-setter Judith Potts (Samantha Bond), pillar of the community and vicar’s wife Becks Starling (Cara Horgan), and no-nonsense dog walker Suzie Harris (Jo Martin). Working tirelessly alongside DI Tanika Malik (Natalie Dew) and her police team, our crime-solving trio put their unconventional methods into practice to catch the killers in six new episodes. There will be three two-part stories.
