I doubt Cricket Australia bought the three-person theory either. But their objective, it would appear, was to move on with as little disruption as possible. Khawaja suggests there was not much of an investigation conducted. One reason he is convinced of this is that he was seated beside Bancroft in the changing room for the duration of the 2018 Cape Town Test, and yet he was never interrogated. He expected, for a long time, to receive a call from the authorities. It never came. He was a thread they never wanted to pull on, lest the whole thing unravel and the truth come out.
