Crunch Time
Since the very start, the harrowing 18-year mystery of Madeleine McCann has been a rollercoaster of high hopes and devastating realities. But right now it's crunch time for the most high-profile child abduction case in history. This week, acting on information from German investigators, police have swarmed on a stretch of Portuguese coastline, close to where the British toddler vanished from her parents' holiday apartment in 2007. They've been desperately searching for evidence, in a race against the clock to prevent the looming freedom of the prime suspect in the case, German paedophile and rapist Christian Brueckner. And, as Tara Brown reports, in this special 60 Minutes investigation, they're not the only ones determined to keep this vile predator behind bars.

Invisible Lady
It is one of the most curious questions being asked of Donald Trump's second term in office. Where on Earth is Melania? While the US President has barely been out of the news, the First Lady has been utterly conspicuous by her absence. Since her husband's inauguration five months ago, Melania has largely given Washington DC a body-swerve, appearing at just a handful of official public engagements. Her defiance of presidential protocol and longstanding White House traditions has been met with head-scratching, scorn and plaudits in equal measure. So where has the First Lady gone? And what does her disappearing act mean for her 20-year marriage with the world's most powerful man?

60 Minutes looks to the stabbing death of Australian Jason Rigby in Fiji and a family's search for answers, plus another look at the Titan submersible disaster.

Murder in Paradise
The words Fiji and murder are rarely used in the same sentence. Similarly, five-star luxury resorts are seldom the scene of violent crimes. Tragically though, the stabbing death of Australian man Jason Rigby in the tourist town of Nadi last December combines all three elements. But this murder in paradise is also one that, so far, hasn't been investigated properly. In fact, if it wasn't for the perseverance of Jason's family, who were forced to hire a private detective to conduct their own inquiries, his killing would probably have been dismissed as not even suspicious. On assignment for 60 Minutes, Nine's Christine Ahern travels to Fiji to report on his family's frantic mission to discover the truth.

Rush of Ego
Two years ago, almost to the day, the United States Coast Guard was tasked with leading the search for the Titan, the submersible missing on an expedition to the wreck of the Titanic. At first there was hope the experimental craft could be rescued, but as is now well known, 90 minutes into its journey and three kilometres below the surface, Titan imploded. All five men on board were killed instantly. Among them was Stockton Rush, the boss of OceanGate, the company which designed, built and operated the doomed sub. Not surprisingly he has been a main focus of the Coast Guard's investigation into what went wrong. Its official report is expected to be released imminently, but as Amelia Adams reports, already this disaster seems to be a case of ego overruling expertise.
