‘You mustn’t do it,’ the dead woman whispered. She was standing right by the bed now. Laura kept her eyes shut tight, the thin sheet forming a barrier in case the ghost turned hostile. ‘You mustn’t kill yourself yet.’ Laura was crying now. Crying from the memory of a decision that had changed everything. ‘I need you,’ the ghost said. ‘I need you to stay alive,’ and Laura threw the sheet forward, jerking upright, the pain in her skull gone. The ghost was gone too.
