Chasing the Ghost - Bob Mayer - Bog

Covert operative Horace Chase has been chasing ghosts his entire life.
First, his Medal-of-Honor winner father who died in Vietnam without ever meeting his son. And left him the legacy of an automatic appointment to the Military Academy at West Point which shaped the next thirty-five years of Chase's life. Then, the ghost of his mother, who died while he was at war in Afghanistan and wounded, causing him to resign his commission and return to the United States, a lost soul.
Chase now wears two hats as a Federal counter-terrorism liaison to the local police department in Boulder, Colorado where he becomes embroiled in two seemingly unrelated cases. Working as a detective with Boulder PD he chases another death, this one the apparent rape/murder of Rachel Stevens, an upscale housewife attending night classes at the University of Colorado. And with his counter-terrorism team he is embroiled in a series of killings involving a militia group, a rogue ex-Special Forces officer, a psychopathic ex-CIA contract mercenary, and ruthless drug runners.
From the streets of Boulder, to the highest railroad tunnel in the world, to a swingers club hiding in plain site in suburbia, Afghanistan starts to look pretty good to Chase.
