Richard Osman will debut a new mystery series later this year.

Pamela Dorman Books will publish Osman’s We Solve Murders this fall. It will be the first in a planned series of the same name. Osman announced the new series on Instagram, writing, “Absolutely DELIGHTED to reveal details of my brand-new book series, ‘We Solve Murders’, about Amy and Steve, a daughter-in-law/father-in-law detective duo. due out in September.”

Osman was known in the U.K. as a television quiz show host before publishing his first mystery novel, The Thursday Murder Club, in 2020. The book became a bestseller, and three more novels in the series followed: The Man Who Died Twice, The Bullet That Missed, and The Last Devil to Die.

We Solve Murders, the publisher says, will follow Steve Wheeler, a retired detective, and his daughter-in-law Amy Wheeler, a private security officer working to protect a famous author. She enlists Steve’s help when a would-be murderer targets her.

Viking, which will publish the series in the U.K., told the Bookseller that the new series “carries Richard’s hallmarks that have made him such a beloved author: the brilliantly relatable characters, his trademark storytelling wit and warmth, and the exciting new international setting.”

We Solve Murders is slated for publication on Sept. 17.
