One Last Scare (Let's Split Up #3‪)‬

The past comes back to kill —when a haunted theme park reopens and true crime turns deadly in the final, blood-soaked mystery of the Let's Split Up trilogy.
The gang thought they were done with murder.

After surviving one too many mysteries, they're finally ready for a normal summer —until Chillshore reopens. Once a beloved island theme park, it shut down after a tragedy no one ever fully explained. Now it's back — rebranded as a spooky attraction that leans hard into its dark past, complete with a creepy mascot known as the Groundskeeper and a guest list packed with horror influencers, true crime celebrities, and supernatural thrill-seekers.

Then the storm hits. No boats. No phones. No escape.

When guests start dying one by one, it becomes terrifyingly clear that the murders aren't random. Each death exposes a piece of Chillshore's buried history.

As paranoia spreads and the Groundskeeper stalks the island, the gang must untangle a web of lies, cover-ups, and long-suppressed guilt before the killer strikes again. Because this time, the mystery isn't just about who is doing the killing —it's about why the truth was buried in the first place.

Dark, twisty, and relentless, Bill Wood's final installment in the Let's Split Up trilogy delivers a blood-soaked locked-room mystery that confronts the cost of turning real tragedy into entertainment — and proves some stories will always come back to haunt you.
