Hawaii Five-0 is to screen a new episode where viewers pick the ending.
The January 14 installment of the CBS crime drama will present the audience with three possible murder suspects.
When a university professor is killed, his boss, his teaching assistant and an ex-student all fall under suspicion, with the viewer picking the ultimate culprit.
Hawaii Five-0 fans can head direct to CBS.com or post the hashtags #theBoss, #theTA or #theStudent to vote. The episode could air a different climax on the East and West Coast, depending on the outcome of the vote in each region.
"I've always felt the most fun aspect of watching a mystery is trying to figure out 'whodunit'," said exec producer Peter Lenkov.
"Now the Hawaii Five-0 viewers will actually get the chance to tell us who they think committed the crime and we will listen. I love that our dedicated and attentive fans will actually play a part in resolving our story."
All three different endings will all be available at CBS.com after the broadcasts.
Hawaii Five-0 airs on Mondays at 10/9c on CBS.
