Malcolm Fox is back...

Fox and his team are investigating whether fellow cops covered up for Detective Paul Carter. Carter has been found guilty of misconduct, with his own uncle - also in the force - proving to be his nemesis. But what should be a simple job is soon complicated by a brutal murder and a weapon that should not even exist.

A trail of revelations leads Fox back to 1985, a year of desperate unrest when letter-bombs and poisonous spores were sent to government offices, and kidnappings and murders were plotted. But while the body count rises the clock starts ticking, and a dramatic turn of events sees Fox in mortal danger.
