It’s every parent’s worst nightmare . . .

Tracy Marley is driving to collect her husband after hours from the gym, the children bickering in the backseat, when a text arrives:

Why not come in, try and find me. You know the code for the front door. Hint: I’m in the office x

It’s late. Tracy’s exhausted. But the kids are excited, and she gives in.

She’s made a fatal mistake.

Instead of finding her husband in the maze of dark, empty corridors, Tracy walks straight into three masked men stuffing cash into a black binbag — and she won’t leave the building alive.

A murdered mother. A missing daughter. A traumatised son.

Detective April Fisher catches the case, and quickly realises time is her enemy.

Because the thieves didn’t just kill Tracy before they fled with the money — they abducted her ten-year-old daughter. And if Fisher can’t work out their next move in time, a little girl will pay the ultimate price.
