The Spice Route Contract — Philip Atlee

They trained him to kill -- but now he's gone rogue -- in this action-adventure thriller by “the John D. MacDonald of espionage fiction” (Larry McMurtry, The New York Times).
 
The CIA didn't mind when the army officer deserted his post in Vietnam and wound up killing a high-level Yemeni official. After all, that's what they'd paid him for. But now it looks like he and his fellow assassins are going after targets of their own choosing -- and it's time for freelance operative Joe Gall to step in . . .

“I admire Philip Atlee's writing tremendously.” -- Raymond Chandler
