A Dead Ringer - Robert Sandilands

To enable a drug dealer boss to get Barton and punish him for a past offense, he sends his thugs to abduct Barton's parents forcing him to try and rescue them. This decides the boss is the only way to get hold of Barton and make him pay. Unfortunately, a few of the bosses' thugs don't obey his rules, thus enabling Barton to keep one jump ahead of them.
