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.
