内容简介：
Adopted at birth, Hannah Conti's attempts to trace her family turned up a mother convicted of murder twenty years ago. Convinced of her mother's innocence, Hannah hires Grace Smith to prove it. Glad of any chance to get out of the office (the boiler's broken and the plumber can't come until next July), Grace uncovers the story of the very messy murder of Trudy Hepburn - a science teacher at St Martin's comprehensive. But along the way she's obstructed by a lot of people who'd rather she stopped digging. On Grace's side is an ex-copper with a shady past (and even shadier present) and Betterman, a mysterious emailer who keeps sending tantalizing clues. To add to these complications, she's been conned into bird-sitting a psychotic parrot, and Terry Rosco, the most chauvinistic cop in Seatoun, is homeless and keeps trying to move into Grace's spare room. And, oh yes - someone keeps trying to kill her...
