As the story progresses, Feeney peels back the layers of these characters. What starts as a typical dysfunctional family drama slowly morphs into something much darker. The dialogue is sharp and often stinging, highlighting the deep-seated animosity between the siblings and the emotional neglect inflicted by the parents.

Unlike Christie’s rational killers, Feeney’s murderer (Rose) acts not out of greed but after years of being overlooked. Rose kills the family members who enabled Daisy’s death. The novel suggests that can be as destructive as active malice.

Critics praised the novel’s “twist on a twist,” though some found Daisy’s ghost perspective gimmicky ( The Guardian called it “clever but chilly”). Unlike And Then There Were None , where justice is external (a judge playing God), Daisy Darker offers —only the dead narrator’s understanding. This aligns Feeney with modern “domestic noir” authors like Gillian Flynn (unreliable women) and Lucy Foley (closed-circle suspense), but her use of the supernatural sets her apart.

The story is set on a tiny, isolated island off the coast of Cornwall, England. Accessible only for a few hours when the tide is low, the island is home to "Seaglass"—a creepy, crumbling, octagonal house made of dark glass. It is here that the Darker family has gathered to celebrate the 80th birthday of Nana, the family matriarch.

Then, Feeney drops the bomb.
