Tsubute takes place almost entirely on the small Japanese island of Yonaguni where a real underwater “pyramid” was discovered by a scuba diver in 1987. Now commonly referred to as the Yonaguni Monument, this megalithic structure appears to have been built before the end of the last ice age, about 10,000 years ago, when the world’s sea levels were much lower than they are today.

Those of you who have read Tractrix will be happy to know that Frank, Tony, Linda and Jim are back! This time, a trip to Yonaguni to investigate the mysterious underwater pyramid involves the four friends in a case of murder and international kidnapping.

The maiden voyage of the team’s newly acquired Learjet begins with a dramatic landing in the Aleutian Islands of Alaska. After a run-in with Department of Justice agents in Tokyo, the team begins to think they should never have left home. When they finally touch down on Yonaguni, a Japanese-American exchange student befriends them and helps them get to know the tiny island of 1,200 people—and the dark secret being protected there. When a  tsubute discovered outside the NWIDI headquarters in Seattle reappears on Yonaguni, it leads the NWIDI team to a startling discovery about the true nature of the island and its original inhabitants.
