The season finale of Only Murders in the Building delivered a shocking twist
that left viewers reeling. After weeks of unraveling the mystery surrounding Ben
Glenroy's murder, the trio finally apprehended the killer: Donna Demeo, the
show's producer. However, the finale didn't end there. As the curtain fell on
the opening night of Death Rattle Dazzle, a new murder was introduced, leaving
Charles's fate uncertain.

The episode began with a flashback of Donna giving birth to her son, Cliff, amidst the chaos of producing a Broadway show. This moment hinted at her unwavering dedication to her career and her deep love for her son. However, her maternal instincts turned dark when she became involved in Ben's murder.
The trio, aided by Loretta, meticulously pieced together the evidence, pointing to Donna as the culprit. Her motive was revealed to be protecting her son, Cliff, who was deeply involved in the production. Loretta suggested that Donna might have been acting irrationally due to illness, which would explain her drastic actions.
The turning point in the investigation came with the discovery of a bloody handkerchief at the crime scene. This seemingly insignificant piece of evidence held the key to unraveling the mystery. It was stained with the same shade of lipstick that Donna wore, linking her directly to the murder.
As the opening night of Death Rattle Dazzle approached, the trio confronted Donna, revealing their evidence and accusing her of the crime. To their surprise, Donna immediately confessed to poisoning Ben. However, she claimed that she never intended to kill him, only to incapacitate him.
The trio, armed with their final piece of evidence – the handkerchief – confronted Donna again. This time, her story changed dramatically. She confessed to both poisoning and pushing Ben down the elevator shaft. Her only request was that they let the opening night continue before arresting her.
Just as the trio was about to apprehend Donna, another crisis arose. The lead actor, Jonathan, was unable to perform due to an overdose of Dr. C's pills. Oliver, stepping into the breach, took on the role, delivering a powerful performance that saved the show.
However, the night took a tragic turn when Howard discovered that Charles had been shot. The bullet had passed through his window, striking him in the chest. As the camera panned, it revealed that the victim was actually a body double, Sazz. The real Charles was safe, but the shooter was still at large, posing a new threat to his life.
The season finale of Only Murders in the Building was a masterclass in suspense and storytelling. It not only resolved the central mystery but also introduced a new one, leaving viewers eager for more. The unexpected death of a character, the revelation of Donna's true motives, and the cliffhanger ending ensured that the audience would be talking about this episode for weeks to come.
