Publisher's Synopsis
Diana's certain her son didn't die accidentally - she's sure her husband murdered him. And she's going to prove it. But would a well-respected, successful man really kill his only son? Is Diana's investigation the desperate reaction of a bereaved mother, or is it - as her brother David believes - the result of something more sinister? David knows that the past casts a malignant shadow over their family, and faced with Diana's growing obsession, he has good reason to fear that her sanity is at stake - and that her descent into madness will leave no one unscathed.
