Shooting the Dead

Special Agent Steve Steele trains with the French Foreign Legion for 2 years to prepare for this mission.
Jenny Lejeune is exposed to the deadly chemical, Salmon knows that Steele knew Jennie, and uses this to get him involved.
Autumn Rae joins him to investigate, and they are joined by Neil Sherwood from the Intelligence Branch of the SAS.
Autumn finds that there are to be 3 airliners used to shock the whole of Europe. She is then captured, and incarcerated in a captured nuclear submarine - if you are wondering where this came into it, the Russians had lost a nuclear sub in the Atlantic, the bad guys had sequestered it. The idea was to use the missile warheads to deliver the deadly chemical to the USA. The advantage being that the chemical dissolves in water.
The US Navy are then involved in stopping the sub.
