Killing Rachel (Murder Notebooks)

Rose's mother and Joshua's father have disappeared. Police inquiries have gone nowhere and the case, it seems, is closed: Rose and Joshua have been told that the police believe their parents are dead. But Rose and Joshua still hold out hope that they are alive. Joshua is determined to follow up his own inquiries, which includes working out the meaning of the cryptic notebooks - the murder notebooks - they have discovered. Then Rose is distracted by odd, desperate messages she receives from Rachel, a former best friend from her school, followed by the terrible news that Rachel is dead. But perhaps Rachel's death will provide one more piece of the puzzle about what has happened to Rose and Joshua's parents.
