Trigger Point

In the middle of a summer heatwave, Explosives Officers ("EXPO") Lana Washington and Joel Nutkins are called out to a Metropolitan Police counterterrorism operation at a London housing estate to investigate a potential bomb factory and a suspected bomb maker, Andy Phelan.

As the bombing campaign intensifies, Lana attempts to find out who is responsible.

Lana struggles to cope with the dangers of her job, but finds support in her budding relationship with Karl.  After a terror group claims responsibility for the mosque attack​, the bombing campaign intensifies with an attack on an LGBT target.

Lana works with New Scotland Yard to hunt The Crusaders before they carry out another terror attack, and she is confronted by the horrifying possibility that someone close to her could be involved in the bombing campaign.

Lana struggles to come to terms with her personal loss, and her failure to prevent the explosion. Supported by a clinical psychologist, she begins to explore her grief and begs Hamilton to allow her to resume her professional duties.

A desperate manhunt for the mastermind behind the bombing campaign plunges Lana Washington's EXPO team into ultimate danger.
