‘CSI” creator Anthony Zuiker is working on a “mystery reality competition” show for ABC.

News of the show first appeared yesterday on realitywanted.com, which featured a casting notice seeking “a budding Sherlock Holmes looking to put your amateur crime-solving skills to the test.”

The unnamed show, from Zuiker and 51 Minds, is “scouring the nation for armchair detectives, perceptive problem-solvers or anyone who believes they have the mental acuity” to compete for a cash prize, according to the show description. Casting runs through March 16.
