The true story of a 6-year-old boy with a dreadful secret.

Oskar's school teacher raises the alarm. Oskar's mother is abroad and he has been left in the care of 'friends', but has been arriving in school hungry, unkempt, and with bruises on his arms, legs and body. Experienced foster carer Cathy Glass is asked to look after him, but as the weeks pass her concerns deepen. Oskar is far too quiet for a child of six and is clearly scared of something or someone.

And who are those men parked outside his school watching him?

Cathy has been a foster carer for over 30 years, during which time she has looked after more than 150 children, of all ages and backgrounds. She has three teenage children of her own; one of whom was adopted after a long-term foster placement. The name Cathy Glass is a pseudonym.
