Curious about every death in Wake Up Dead Man: A Knives Out Mystery and how each one drives the investigation forward? As Benoit Blanc uncovers layers of deception in a small religious town, hidden motives and long-buried secrets emerge. These revelations, combined with key character actions, shape the entire Knives Out 3 mystery.
Here is a breakdown of who dies, who kills, and why in Wake Up Dead Man: A Knives Out Mystery.

Everyone who dies in Wake Up Dead Man: A Knives Out Mystery
In the present-day events of Wake Up Dead Man, four main characters die: Monsignor Jefferson Wicks, Samson Holt, Dr. Nat Sharp, and Martha Delacroix. Additionally, past deaths central to the plot include Grace Wicks (Jefferson’s mother), Prentice Wicks (his grandfather), and a man killed by Reverend Jud Duplenticy during his boxing career.
Dr. Nat Sharp fatally stabbed Jefferson Wicks with a hidden knife after Martha Delacroix drugged Wicks’s flask. Samson Holt impersonated Wicks in a staged resurrection, and Sharp killed him to steal the diamond.
Martha poisoned Sharp with the same drug he had prepared for her, and his body dissolved in acid. Martha then took a fatal dose of the drug and died after confessing her crimes and praying for forgiveness.
Who is the killer in Knives Out 3, and why did they murder?
Dr. Nat Sharp murdered Jefferson Wicks under Martha Delacroix’s direction. After Wicks discovered the location of a priceless diamond hidden in his grandfather’s tomb, Martha, who had spent years guarding the diamond’s secret, feared he would exploit it. To stop him, she planned his death.
Martha drugged Wicks’s flask, and Sharp stabbed him with a concealed knife. They arranged for Samson Holt to impersonate Wicks in a staged resurrection and recover the diamond. Sharp betrayed them by killing Samson to steal the diamond, but Martha poisoned him before he could act further.
Martha later took a fatal overdose after confessing everything to Reverend Jud Duplenticy. She and her co-conspirators committed the murders to stop the diamond from falling into corrupt hands and to preserve Wicks’s public image.
