DS Mackenzie Clarke (Anna Samson) is back, fresh from having wrecked another of Glenn’s (Tai Hara) weddings and determined never to follow her heart again.
But ignoring her heart won’t be easy. The arrival of her force-of-nature mother Jillian (Kerry Armstrong) puts Mack's mettle to the ultimate test and there's something undeniable about the raffish charm of the new pathologist Leo (Jacob Collins-Levy). And as for Glenn, who has gone away to ‘find himself’, well that's a whole other puzzle for Mack to try and solve ...
And, while Dolphin Cove may still look like paradise, it continues to serve up a steady stream of baffling murder mysteries – from the artist stabbed in full view of the public, to the wildlife worker dead in a locked cassowary cage. Mack will solve it all with her usual brilliance, and the off-beat help of her loyal team.
