Nobody's son

When Cathy is asked to foster little Alex, aged 7, her immediate reaction is: Why can't he stay with his present carers for the last month?

He's already had many moves since coming into care as a toddler and he'll only be with her a short while before he goes to live with his permanent adoptive family.

But the present carers are expecting a baby and the foster mother isn't coping, so Alex goes to live with Cathy.

He settles easily and is very much looking forward to having a forever family of his own.

The introductions and move to his adoptive family go well.

But Alex is only with them for a week when problems begin.

What happens next is both shocking and upsetting, and calls into question the whole adoption process.
