Former army interrogator Jay Ryan is enjoying the quiet life after leaving the military far behind or so he thinks. But old habits die hard and he's quickly thrust back into the thick of things when a disgruntled scientist, backed by the Australian security industry, develops a weapon of mass destruction a hybrid strain of Anthrax to be used to create panic in a population apathetic to crime prevention. Only one batch of Anthrax inoculations can resist the deadly new strain, and it was given to five military interrogators. One of them was Jay Ryan. When the other four disappear, Ryan is the last interrogator left with the antibodies to defeat the deadly Anthrax strain. As he wages a one-man war against enemies both known and unseen, there's only person he can trust or can he? Winning the war may have devastating consequences for the last interrogator.
