The acclaimed but outspoken auteur reluctantly chaperones his ‘muse' - rising star Mimi McQuinn. But Mimi is then murdered during the premiere.Jack and Kate are on the case, focussing their attention on Werner himself, and also on influential but corrupt and unscrupulous film critic Erin Daniels, and her besotted and feckless son Lucian, both of whom appear to have grudges and motive.Meanwhile, Jack and Kate navigate their way through various challenges in their new life as a couple – but when cabin sharing starts to become cabin fever, they're forced to redefine their living arrangements. All's well that ends well – what they have transcends such mundane concerns. Also, we meet Carole Merryweather, a long-term passenger, who is celebrating a milestone in her life on board the ship.
