A Brisbane River fisherman finds some items in his crab pots that just shouldn't be there. And although the crabs are full and plentiful he didn't bait his traps with human hands and feet and rightly contacts the police. And so starts the Mud Crab Case.
Lee Birch, one year on from trapping and disposing of the djinn, Kolb, is in training at the Queensland Police Academy. Senior Sergeant Harriet Blackmon has a new recruit and while Lee is working towards graduation she's also working cases on the side and picking up valuable experience. The Mud Crab case starts to chew up a lot of her time and looks like involving an old nemesis.
But her past is about to catch up with her in the worst possible way. When Michael Torrens was given a second chance there was an expectation that he would return after his djinn hunting mission was over. Now, as Lee Birch, Michael Torrens has no intention of going back. Not until Lee's life is lived to the fullest at least.
However, the gatekeepers have started the process of getting her back, and it's going to get messy.
