Nicola Coughlan is heading to London — and she’s bringing her mystery-solving instincts with her. The DERRY GIRLS and BRIDGERTON star has officially joined the cast of ONLY MURDERS IN THE BUILDING for its highly anticipated sixth season, and it’s the kind of casting news that feels almost too good to be true.

Coughlan is one of several major new additions to the show’s ensemble, joining a frankly staggering lineup of British and Irish talent that includes David Tennant, Jodie Whittaker, Jim Broadbent, Richard Ayoade, Adrian Lukis, and Kathryn Hunter. The show’s official social media account broke the news in typically playful fashion, urging followers to keep calm and update the case file — which, honestly, is exactly the energy we needed.

For anyone new to the series, ONLY MURDERS IN THE BUILDING follows three amateur true-crime obsessives — played by Steve Martin, Selena Gomez, and Martin Short — who investigate murders connected to their upscale New York apartment building while documenting everything for their podcast. Season 6 marks a significant first for the show, as production has relocated to the UK, with the trio’s investigations taking them across the Atlantic to London. It’s the first time the series has filmed outside the United States, and with a cast of this calibre waiting for them on the other side, the move feels more than justified.

No official release date has been confirmed just yet, but all ten episodes of ONLY MURDERS IN THE BUILDING Season 6 will be available on Disney+ in Ireland and internationally when it arrives.
