My name is Kate. I volunteer at a Missing Persons helpline - young people who have run away from home call me and I pass on messages to their loved ones, no questions asked. I don't get many phone calls, and those I do are usually short and vague, or pranks. But this morning a girl named Sophie called. I'm supposed to contact her parents to let them know their child is safe. The problem is, Sophie isn't safe. And Sophie is my daughter.
