DI Nikki Galena gets a series of anonymous calls. She is told the place, time, and who will die.

But the messages are in a secret language used only by villains. Nikki and her team must decode the riddles and work out where the threats are coming from.

Meanwhile, the fens have been hit by a series of “designer burglaries.” It appears that a new gang of thieves are stealing to order.

And things get very close to home when a friend of Nikki’s mother dies suddenly and perhaps suspiciously.

Do any of these events relate, and can Nikki stop the thieves on the fens, before anyone else dies?
