How many episodes will The Marlow Murder Club Season 3 be?

Per a PBS press release, Season 3 will feature “three gripping new murder mysteries told across six episodes.” Daniel Rusteau co-wrote the first two episodes of Season 3 with the author of The Marlow Murder Club book series, Robert Thorogood. Amy Reith serves as the writer for Episodes 3 and 4, while Julia Gilbert penned the final two episodes of the season.

Is there a trailer for Season 3 of The Marlow Murder Club?

PBS released its first teaser for the show’s third season on June 29. DI Tanika Malik (Natalie Dew) opens the teaser by declaring, “Another person was found dead this morning,” and notes that the police believe the person’s death “wasn’t an accident.”

As expected, the Marlow Murder Club ladies quickly jump on the case. “To convict his killer, we have to catch them first,” Judith (Bond) tells Becks (Horgan). What follows is footage of the trio putting their detective skills to work to catch the killer.

“Oi! Come back here!” Suzie (Martin) yells while pursuing a potential suspect. The tease ends on a suspenseful note, as Judith tells the others, “I think I know who the killer is.”

What will happen in Season 3 of The Marlow Murder Club?

“Now an established part of newly promoted DI Tanika Malik’s crime-solving gang, retired archaeologist Judith Potts, dog walker Suzie Harris, and vicar’s wife Becks Starling are back and bringing their unconventional methods to a string of high-profile murders,” the logline for Season 3 reads. “From the sudden death of the town’s beloved mayor – the nicest man in Marlow – to a celebrity chef found dead at the launch of his cookbook with half the town in attendance, the team will be working under the watchful eye of the Marlow community.”

The description continues, “They’ll also be called to action at a university reunion in an eerie manor house where, in a surprising twist, Becks finds herself amongst the suspects. Could this case threaten our amateur sleuths’ roles as civilian advisors?”
