Halfpace is the most organized group of assassins in the 20th century. They employing hundreds of "Bluejays"; well-trained killers, doctors, ex-military, businessmen, and spies. Bluejays are used to assassinate high-profile government officials, terrorist group leaders, or an ex-wife if you can afford them. New members don't last more than a few months.
Owen Tardy is a pediatrician who suddenly finds himself on the FBI's most-wanted list. He's never heard of Halfpace, let alone killed anyone. Labeled a "Bluejay", he becomes dead-set on proving his innocence.
