Laz is an undercover cop coming in the from the cold. He's a social outcast and a rebel who has been on the streets too long. His return to the traditional police force - and to the bombing investigation team - has explosive results. Laz doesn't rejoin the human race easily. But he proves his value beyond question when he provides the hard-pressed team with their first solid lead - a stolen car garage that worked on the bomb car. But concealing the truth of who you are is a hard habit to break.

Megan, the analyst, takes off on a tangent of her own. She decides to pursue the bombers by assuming they require large amounts of money to finance the bomb and their continuing silence. She uncovers a possible suspect whose very distinctive description leads her to the world of sexual offences. She discovers Kelly, an angry rape victim who is disillusioned with the police force's inability to convict offenders. Megan has to batter her way through Kelly's defences to get a photo-fit of her vicious attacker .. and a possible lead to the identity of one of the bombers.

For the first time we close in on the bombers and confirm how dangerous and renegade are their personalities. We see why the bombing investigation has battled for every slim lead. Even the criminal underworld is afraid of them. But, under increasing pressure from the police, they are beginning to make their first real mistakes.
