The case has taken many twists and turns in Only Murders in the Building Season 5, as is usually the situation for every season. There are so many clues pointing in different directions, the trio of Charles (Steve Martin), Oliver (Martin Short), and Mabel (Selena Gomez) are finding it tough to figure out what's real, what's not, and who is responsible for killing both Lester (Teddy Coluca) and Nicky (Bobby Cannavale). While the latest revelation doesn’t hint at the identity of the killer (or killers), it does threaten the future of the Arconia.
