A sixteen-year-old boy is missing in a Tel Aviv suburb.
His mother is worried. Inspector Avraham Avraham is not. It is unheard of for children to vanish in this city.
But the boy has disappeared without trace. The parents are wretched, the neighbourhood suspicious; the boy's tutor harbours a secret.
Avraham's only answer is so unthinkable, it will take all his courage to face.
