Synopsis
Nadir coaches a local youth into posing an informant in order to use some shaky information from gang leader Jordan Tomlin as collateral for a raid on a supposed arms deal taking place between Asher Campbell and a well-known gun dealer. However, the sting backfires when only two of the promised eight automatic weapons are recovered. Perkins assists De Costa on her first investigation with the Child Abuse Unit when they investigate a possible case of neglect, which turns out to have been something much more sinister. Meanwhile, a witness finally comes forward to confirm James Tennant's alibi after a reconstruction of Amy's disappearance is broadcast on television.
