Nine Lives Summary: The Complete Story
SPOILER WARNING: This section reveals the full plot, including the ending.
The book opens with nine unconnected people receiving a cryptic list in the mail.
The list contains nine names, and each recipient sees their own name on it.
No return address, no explanation, no demands.
Most recipients dismiss it as a prank or a glitch.
Frank Hopkins, a resort owner in Maine, is the first to die.
He is drowned in a tide pool during his morning walk, still clutching the list.
Detective Sam Hamilton takes the case in Kennewick, Maine.
Matthew Beaumont, a stressed suburban father, is shot in the back while running through a conservation forest.
The FBI gets involved once two names from the list surface as murder victims.
Jessica Winslow, an FBI agent in Albany, recognizes the danger.
She begins cross-referencing the names but finds no immediate connection among the living recipients.
She flees to a remote cottage in Maine to hide from whoever is hunting them.
A professional hitman named Tod Fischer is hired to track her down.
Meanwhile, Arthur Kruse, an oncology nurse, is murdered in his home.
The killer uses carbon monoxide poisoning from a canister hidden in his closet.
Kruse was under local police protection at the time.
Ethan Dart, a songwriter in Austin, and Caroline Geddes, an English professor in Michigan, begin a deep digital correspondence.
Their shared fear and love of poetry draws them together.
They arrange to meet at a remote cabin in Illinois.
Both are poisoned with benzodiazepines and injected with morphine while they sleep.
They die in each other’s arms.
Jay Coates, an aspiring actor in Los Angeles, is beaten to death with a baton on a dark street.
Detective Sam Hamilton makes the crucial connection.
He researches the history of the Windward Resort, Frank Hopkins’s property in Maine.
In 1956, a group of children calling themselves the “Pirate Society” held an initiation rite.
They left a ten-year-old girl named Faye Grant in a crevice at the stone jetty during low tide.
The children expected her to survive the rising water.
Instead, she drowned alone while the other children played board games and forgot about her.
The parents of the nine people on the list were those children.

Jack Radebaugh, a retired businessman and author, is revealed as the mastermind.
He was born Jonathan Grant, Faye’s older brother and leader of the Pirate Society.
Years after his sister’s death, Jack lost his own daughter and received a terminal glioblastoma diagnosis.
He decided to enact what he called “karma.”
He would kill the children of the original Pirate Society members.
Only Frank Hopkins was an original Pirate; the others were his peers’ offspring.
In the climax, Jack murders his neighbor Eric out of personal justice.
He then travels to the Windward Resort.
He writes a comprehensive confession letter and hides it in a Peter Pan book in the hotel library.
Jack drowns himself in the same crevice where his sister died.

She wakes from her coma in the hospital and learns the truth.
