#3 in the Doc Adams series.
Doc Adams series - Leader of the Daisy Ducks, a team of commandos in Vietnam, Roantis had stashed a fortune in Kowloon at the war's end. He wants Adams to help him retrieve the loot, but before they can plan the trip, the veteran is almost a dead Duck from a sniper shot. While Roantis recuperates, the dentist acts on suspicions that his friends' former comrades are guilty of the attack. Adams meets them all and they are gathered together at the book's furious, blood-chilling climax, even Roantis (well again) and the "Daisy," for whom the Ducks were fighting.
