Stamp brings surprise guest in to custody - former PC George Garfield. They start reminiscing about the past. Ackland recalls the death of PC Melvin, a large HGV tanker spewing its load over the streets of Sun Hill, and the Sun Hill firebombing, during which six much-loved officers died - Worrell, Spears, Harker, Monroe, Riley and Hayward - as well as the events leading up to the attack, which saw the death of Conway.
