The team investigate a petrol-bomb attack in which 19-year-old Asif Khan is badly injured. His father, Jamaal, has been involved in a bitter row with reprobate property developer Gregor Forrester, and old enemy of Jack and Martha's, who has so far managed to elude conviction. Fingerprint evidence suggests that a familial relative of David Eboda, Forrester's right hand-man and former ex-cop and mentor to Jack, is the personal responsible for the attack, but a full DNA profile of Forrester's son, Zak, identifies him as the culprit, and reveals that he is Eboda's son, not Forrester's. When Zak mysteriously disappears, Jack decides to press Eboda to lead him to the truth.
