ABC’s summer lineup will include “CSI” creator Anthony E. Zuiker’s first primetime reality series “Whodunnit.”

Alphabet ordered nine episodes that feature 13 contestants using a variety of crime scene investigation techniques to solve a series of fictional crimes and determine who among them is the killer. In the final episode, one player will unmask the killer and win $250,000.

“I’ve built a career telling crime stories, and if there’s one thing that I’ve learned, especially from ‘CSI,’ it’s that the audience loves to solve the mystery,” Zuiker said.

“Whodunnit?” is produced by Zuiker’s Dare to Pass shingle and 51 Minds. Zuiker and Cris Abrego will serve as exec producers.
