ITV Quiz viewers were left in total amazement at the moment the truth behind Charles Ingram 's Who Wants to be a Millionaire? cheating scandal was uncovered.
The limited series follows the shocking true case of Ingram, who cheated on the hit quiz show in 2001.
Tonight's second episode of the three-part series showed fans how a sound man's suspicions led to the crew finding out Charles had cheated his way to bagging £1million.
The sound man working on the gameshow at the time had picked up Charles' cheating by the pattern of mysterious coughs from an audience member.
He listened back to a video from the show, and analysed the noise coming from the audience alongside Celador producer Paul Smith, who was played by Mark Bonnar.

"There, right there. A cough," the sound man explained. He added: "I don't definitely know, but I think there's a pattern."
The team listened back and realised Charles had changed his original answer after a cough emerged from the crowd.
Paul, who was on the brink of disagreement, called Celador's PR officer and explained that the team were convinced Charles had cheated.

Charles' wife and brother-in-law had also previously participated in the show.
He said: "We've had another millionaire. Except, I think... we think something's not right. We think the guy may have cheated."
Taking to Twitter, fans shared their amazement at how the sound man had worked out the cheating pattern.


One penned: "Here to all the techs in the tv industry. That sound ringer is a legend #quiz."
Another wrote: "OOI OI THE SOUND MAN DID HIS TING".
A third shared: "Looking back, it’s unreal how they thought they’d get away it. I cringed my way through tonight’s episode, the coughs are so blatant! #Quiz ".
Later in the show, several calls were made to ITV's PR officer and ITV Entertainment Commissioner Claudia Rosencrantz, where a meeting was then held to discuss the potential cheating crime.
They agreed it was a theft to steal the large sum of money from a TV show.
*Quiz continues tomorrow night at 9pm on ITV.
