Only three people know the truth of what happened on a lonely desert road in the middle of the Australian Outback four years ago.
The first, Peter Falconio, is missing presumed dead after allegedly being gunned down by the side of the Stuart Highway, which runs ruler-straight through the scrub and red sand dunes of the Northern Territory.
The second, Bradley John Murdoch, is the gunman accused of killing him on that pitch-black night.
Last week, the 47-year-old former mechanic and alleged drug runner went on trial for murder in the Northern Territory Supreme Court in Darwin, the capital of Australia's tropical north.
The third person is Falconio's former girlfriend, Joanne Lees, who spent the week having her story of that night examined in minute detail.
The Australian media is calling the case 'the trial of the decade', the most sensational case since Lindy Chamberlain was wrongly accused of murdering her baby, Azaria, in the shadow of Uluru, then known as Ayers Rock, in 1980.
