What Happened Next Summary: Edwin Hill’s Cold Case Thriller

Reid escaped in a rowboat with baby Charlie while paper lanterns drifted overhead. Isaac bled out in the woods. Authorities presumed Mark froze to death, though no body was ever recovered.

Detective Wendy Burrows led the original investigation. Months later, her car rolled off a cliff into the lake and she drowned.

Charlie Comes Home

Twenty-five years on, Charlie works as a production assistant at a Boston public radio station. His producer, Julian Allende, pushes him toward a true-crime series, and Charlie drives his missing father’s restored 1983 yellow Volvo back to Hero.

The podcast is called What Happened Next. Charlie’s stated goal is to learn who his father actually was, and he begins recording almost immediately.

His childhood friend Seton Haviland, now a local police officer and Isaac’s daughter, tells him to leave the past alone. Charlie’s brother Reid and their mother Jane react with open anger when he reveals the project at Idlewood.

Elsewhere in town, Andrea Haviland is fighting a luxury development at Burkehaven, built by Paul Burke and designed by Reid Construction. Paul is an old family friend and a New York talent manager.

Fire, Assault, and a Body

The next morning, Charlie spots black smoke while running past Burkehaven. The half-finished luxury house is burning.

As he moves toward someone struggling in the courtyard, Charlie is struck from behind with a tree limb and knocked unconscious. Seton arrives and helps him pull an unconscious Andrea Haviland out of the fire.

State Police Detective Duncan Gilcrest takes over the arson and assault case. That evening, at the Landing pub, Charlie sits beside a man with glasses and a ponytail and realizes it is his father, Mark Kilgore, alive.

Mark speaks vaguely about friendship and worry, then leaves. Charlie saves the glass he drank from for a DNA test.

At the same pub, Charlie meets Freya Faith, a former television actress famous for a police procedural called Scene of the Crime. Freya is managed by Paul Burke and has come to Hero to escape a longtime stalker.

Freya picks apart the 2001 story as if it were a script. She asks why Mark would let Isaac escape, how a twelve-year-old could hear dialogue from a hundred yards away, and why Jane was left alive.

Then police find a body in the burned rubble. Jane Reid was killed by blunt-force trauma to the head before the fire was set.

The Web Tightens

Charlie learns that local lumber supplier Vance Moodey had been quietly dating Jane. He also learns that Jane planned to place Idlewood into a land conservation trust, which would block Reid from selling or developing it.

Reid Construction is deep in debt. The trust would have closed off his only way out.

Freya’s truck is then vandalized with the words “WHAT HAPPENED NEXT” written in blue nail polish. Reid is caught hiding in a brook near Freya’s apartment after breaking in, but he denies being the stalker or the killer.

Charlie confronts Reid on the Idlewood dock about the debts and the lies surrounding 2001. Reid denies killing Jane, admits he invented the detail about Isaac saying “my love,” and swims off into the cove.

Late that night, Charlie sees a wet, frantic figure on the shore. It is Mark Kilgore, who mutters “I tried… I should have known” and disappears into the woods.

Moments later, Charlie swims into the cove and finds Reid’s body floating in the lake. Reid suffered a fatal blow to the back of the skull before drowning.

The Sugarhouse and the Ridge Trail

Charlie goes to Paul Burke’s converted barn at Burkehaven Farm and finds signs of a violent struggle and a blood-stained chef’s knife. In the outdoor sugarhouse, he finds Mark bleeding heavily from a stab wound.

Freya’s German shepherd, Ginger, leads Charlie up the ridge trail to an abandoned hunting cabin at the summit. Inside, Paul Burke holds Freya hostage at gunpoint.

Detective Gilcrest arrives and Paul shoots him in the shoulder. Charlie, armed with a single-shot target rifle, forces Paul to lay out the full account.

What Actually Happened

Paul Burke had stalked Freya Faith for years. Isaac Haviland discovered the secret and blackmailed Paul for fifty thousand dollars.

To remove Isaac, Paul manipulated twelve-year-old Reid Kilgore, telling the boy that Isaac was destroying his family and that he needed to “cut out the evil before it takes root.” Reid stabbed Isaac.

Mark Kilgore took the blame and went into hiding to protect his son. Jane learned the truth and shielded Reid, using burner phones and cash to keep Mark supplied while he lived off the grid.

Detective Wendy Burrows had also connected Paul to the case. Paul found her passed out in her car and pushed it off the ledge into the lake.

Twenty-five years later, Jane recognized the phrase “cut out the evil” — a phrase both Reid and Charlie had repeated — as Paul’s. She threatened to go to the police.

Paul struck Jane with a two-by-four at Burkehaven, set the building on fire, and attacked Charlie when he stumbled onto the scene. When Reid realized Paul had killed Jane, he confronted him and was struck down and drowned in Hero Lake.

Seton arrives in a police helicopter. Paul is disarmed and arrested.

The Ending

Two weeks later, Mark Kilgore is cleared of all criminal charges. Seton then shares the DNA results: Charlie’s DNA matches Mark, but it does not match Jane Reid.

Charlie’s biological mother is Aunt Hadley, Jane’s sister, who had a brief relationship with Mark twenty-six years earlier. Jane adopted Charlie at birth and raised him as her own.

Charlie decides not to release the podcast or sell his family’s story. He resigns from the radio station and stays in Hero to run the family firm.

He donates Idlewood’s land to conservation and begins rebuilding a life alongside Seton and his reunited father.
