Shatter is a psychological thriller written by the Australian author Michael Robotham that was published in 2008. Professor Joseph O'Loughlin (referred to as Joe throughout the novel) is tasked by the police with stopping a woman, Christine Wheeler, from committing suicide, only to fail. When Wheeler's teenage daughter appears onto his doorstep, she insists that her mother would not have jumped off a bridge as she did, for she was not suicidal and had a fear of heights.
