Chloe, Dan, and Lucifer tackle the murder of a wealthy real estate mogul who owned the entire block that includes Lux. Their investigation turns up multiple people with motives, including the victim's son, his fiancée who comes from modest means, and a rival real estate developer who wants to tear down the whole block, including Lux, to put up a shopping mall. The developer is about to get her wish until Chloe manages to get the building that houses Lux declared a historic landmark. Meanwhile, Charlotte becomes intimately friendly with Dan and starts to strongly believe that Chloe is the reason Lucifer wants to stay on Earth. Charlotte meets with a bomb-maker and plans to blow up Chloe when she steps into her car.
