This is a fact: Ryan Summers walked into Three Rivers College and killed thirteen women, then himself.

But no one can say why.

The question is one that cries out to be answered - by Ryan's mother, Moira; by Ishbel, the mother of Abigail, the first victim; and by DI Helen Birch, put in charge of the case on her first day at her new job. But as the tabloids and the media swarm, as the families' secrets come out, as the world searches for someone to blame... the truth seems to vanish.

Book 1 in the DI Helen Birch series.

DI Helen Birch is recovering from major surgery, housebound and exceptionally bored. Her boss, DCI McLeod, has made it crystal clear: she is not to take on any work until her recuperation is over.

In her absence, Amy Kato is promoted to sergeant and is given a maddening case to work on: Edinburgh is being plagued by an anonymous vigilante. He started small, meting out punishment to obnoxious boy racers and other antisocial folk, but his behaviour is escalating. Amy can tell from the anonymous online paper trail he leaves. His writings are increasingly confident, and increasingly threatening. And yet he also seems to be invisible: her team can find no clue as to his identity, and no trace of his whereabouts.

At first, McLeod doesn't see the case as a huge deal. Concerned, Amy comes to Birch in secret to ask for help, and Birch finds it impossible to resist taking action: placing her directly in the path of immense danger...

Book 5 in the DI Helen Birch series.

At 8am the first shots are fired.

At 1pm, the police establish the gunman has a hostage.

By 5pm, a siege is underway.

At 9pm, DI Helen Birch walks, alone and unarmed, into an abandoned Borders farmhouse to negotiate with the killer.

One day. One woman. One chance to get everyone out alive.
