Says Zuiker: "The inspiration for Marg Helgenberger's character, Catherine Willows, was a real 'CSI' from Las Vegas named Yolanda McLeary. She was incredibly sexy and tough. She was the type of woman that could work the graveyard shift and then go out with the guys afterward for beers."

ABC is adding more to its summer slate with the unscripted addition of Whodunnit?.

Billed as a murder mystery reality series, the competition comes to the network from CSI co-creator Anthony E. Zuiker and will get a nine-episode summer run, The Hollywood Reporter confirms.

Produced by Zuiker’s Dare to Pass and Cris Abrego's 51 Minds, Whodunnit? takes a lighter approach to the procedural with contestants vying to determine which one of them committed a fictional murder. The 13 would-be sleuths will follow the Clue formula, imploring real life crime scene investigation techniques to uncover and discern the staged evidence.

Much like the movie inspired by the classic game, contestants will also stay together in a glitzy estate. A new crime will be presented each week so that they might advance in the game. The finale will find one player unmasking the killer to win a $250,000 prize.

CSI, itself inspired by Discovery unscripted venture The New Detective, has already spawned two spinoffs in CSI: New York and the late CSI: Miami. Zuiker's Alice in Wonderland update recently received a pilot order at NBC.

ABC recently added Canadian drama Motive to its summer lineup.
