Primrose U.S.M.C‪.‬

The Vietnam War long over, Zachary Taylor Primrose and his former comrade in arms, Patrick Thomas Knight have started their own PI firm in Honolulu. When Sergeant T.J. DeSoto, U.S.M.C., disappears in the Middle East, his wealthy grandmother becomes Special Island Investigations' first client. Primrose puts together his old team from 'Nam: Toms, McPotts, and Slipps, and with the unofficial help of Colonel Easy, they manage to get into Iraq only days before war breaks out.

Colonel Easy has a favor to ask in return for his help: a supposedly "piece-of-cake" mission to root out a cell of international terrorists before the war starts. The non-stop action takes the recommissioned team, along with Sergeant DeSoto, from Iraq to Syria, Lebanon, Morocco, and the Indian Ocean on the trail of international intrigue on a bigger scale than they had could ever have imagined.
