The team are confounded when a tourist is stabbed whilst travelling down one floor, all alone, in a hotel lift. It transpires that the victim was severely ill, and coming to St Marie had been on her bucket list. But the case takes an even stranger turn when the team discover the victim's written bucket list, and travelling to the Caribbean is nowhere to be found!

As our team start to investigate the victim's loved ones, they discover a family with numerous skeletons in their closets - whilst an ominous woman watches everything unfold from the shadows. Meanwhile, an old face returns to St Marie – but isn't met with open arms from everyone on our team.

It's the team's most confounding puzzle yet when a passenger boards a flight to Dominica but then seemingly vanishes mid-flight, only to be found back on Saint Marie soil... shot dead. The pilot and flight attendant deny ever seeing the victim on their plane, raising the team's suspicions.

Two further suspects are found back in Saint Marie – it transpires the victim had been caught up in a messy love affair. Neville starts to question whether he's losing his mind, seriously doubting himself for the first time, until all the pieces of the puzzle finally fit together, revealing the startling truth. Meanwhile, an old face has returned, and Neville has a huge decision to make.
