When the vehicle is traced to the boy's mother, they arrive to find her badly beaten and in the comfort of one of her neighbours. When she accuses her husband of rape and assault, De Costa is certain that an answer phone cassette, which was placed to record during the attack, will prove the husband's innocence or guilt.

Whilst investigate a number of graffiti attacks on a Jewish graveyard, Thatcher finds a link between the time of the disturbance and De Costa's investigation.
