It appears a mystery is afoot on social media as Steve Martin gave fans a sneak peek behind the scenes of Only Murders in the Building Season 2.

The actor, executive producer, writer, and co-creator of the Hulu comedy shared a photo featuring his fellow series regular costars Selena Gomez and Martin Short alongside two others, one of which is comedy legend Andrea Martin (Difficult People, SCTV). “On the set of ‘Only Murders in the Building’ season 2. Great cast surprises that are no longer surprises,” Steve Martin wrote alongside the image.

The real mystery is, who will Andrea Martin play in the series about an unlikely trio of murder podcast enthusiasts who find themselves entangled in a series of crimes set in their swanky Upper West Side apartment building. As previously announced, Season 2 will see the addition of Cara Delevingne who will play Alice, an art world insider who is pulled into the latest mystery.

Shirley MacLaine and Amy Schumer are also reportedly involved in Season 2 as Martin Short teased to Deadline in January that he had filmed scenes with both actors.

Season 1 came to a close with a cliffhanger involving Gomez’s Mabel as she was found kneeling over the building’s dead landlord and dragged away in handcuffs alongside Charles (Steve Martin) and Oliver (Martin Short). But they didn’t commit the crime, leading Season 2 to ask the question, who did?

Hulu has confirmed Andrea Martin’s casting after TV Insider reached out for comment. They also confirmed the casting of Zoe Colletti (the girl pictured alongside the other stars, above).
