Flu season is in full swing, surrounded by germs and illness, SSA Ellie Iverson reacts like any new mom, with hand sanitizer at the ready and a desire to keep away from anti-vaxers. Her newly hatched germaphobia escalates when Delta A is asked to investigate animal rights activists and a missing laboratory monkey. An incident in Lexington, Virginia leaves the Director of the FBI fighting for her life. A sudden violent death of a colleague in Washington, the discovery of a spate of deaths linked to the Intelligence Community, herald the arrival of an old friend from the UK with news of a potential global disaster. With biker gangs, drugs, grudges, and a plethora of 'accidental' deaths in the mix, this is no ordinary flu season.
