Detective Jane Tennison made a bad choice.

She was the one who put in a transfer to the quiet, local police station in Bromley, keen to escape the relentless pressure of her former West End department.

Now she regrets her decision. The tedium of petty crime investigations even makes her question remaining in the force.

But then a complicated domestic assault case lands on her desk - one that might still result in a murder charge if the victim dies of his injuries.

The warring neighbours who witnessed the assault intrigue Jane. The case has a sinister underbelly, she can sense it. And when Jane discovers a handsome young boy had recently disappeared after the tragic death of his girlfriend, every family in the private close becomes a suspect.

As Tennison hunts for the link between the crimes, she uncovers a truth more shocking than she could have contemplated. One that will either make her career - or break it.
