Only Murders in the Building

The mayor warns the trio about the billionaires, sending them to investigate further at a villainous lair upstate — as Oliver boots it in an attempted escape.

Mabel gathers a ragtag group to crash an exclusive ladies night. While trying to save the Arconia from being sold, Charles and Oliver accidentally end up in couples' therapy.

Told through the lens of one annoying robot who may hold the keys to more secrets than anyone realized — the Arconia throws one last party as the residents discover that a killer may still be in their building.

With the clock ticking, the trio doubles down to bring "new" and "old" forces together to bring down a killer — ending in one explosive showdown and the reveals they've been chasing all season.
