DI Birch

This is a fact: Ryan Summers walked into Three Rivers College and killed 13 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.

Thirteen years ago, DI Helen Birch's little brother Charlie disappeared. Two days ago, Birch was part of a raid on one of Scotland's most feared criminal organisations. Yesterday, Charlie came back.... Now Birch has a choice: save her career, or save Charlie? As she interrogates her brother, we see his story, in a brilliantly tense and clever story about what people will do to survive and the lines they'll cross to protect those they love.

Robertson Bennet returns to Edinburgh after a 25-year absence in search of his parents and his inheritance. But both have disappeared. A quick, routine police check should be enough - and Detective Inspector Helen Birch has enough on her plate trying to help her brother, Charlie, after an assault in prison. But all her instincts tell her not to let this case go. And so she digs. George and Phamie Bennet were together for a long time. No one can ever really know the secrets kept between husband and wife.

At 8 a.m., the first shots are fired. At 1 p.m., the police establish the gunman has a hostage. By 5 p.m., a siege is underway. At 9 p.m., 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.

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.

When a young Vietnamese girl goes missing in Scotland, DI Birch knows there is more to the case than meets the eye. Her colleagues won't take it seriously - but Helen's instinct tells her that Linh is in mortal danger. Beatrice knows something terrible has happened to three young people in Edinburgh. She can see them in her mind's eye - frightened and alone, desperate for help. Ever since she was a child, she's had visions of the future - and she's ignored them before, with dangerous consequences. This time, she must help the police find Linh.
