The Bamboo Bomb (1965)

Have they got the bomb? - or are they bluffing? Either way, they can blow up the peace by a single explosive action planned to take place somewhere in the Malay archipelago. Intertrust assigns agent MARK HOOD to stop it. His order: If it's a nuclear bomb test, sabotage it. If it's a political bluff, expose it... But how? To accomplish the mission, HOOD must get across the Strait of Malacca - by invitation. And the only way he can do this is to become an ally of the plot-masters themselves... On an assignment that leads him from Singapore to Sumatra to Sarawak, HOOD faces brutality, treachery, murder, and finds that all his powers are challenged by one of the most ingenious peace-blasting plots that Intertrust has ever encountered.
