The Intimidators by Donald Hamilton

It was a double mission this time. But Matt Helm could handle it....

One to terminate a top-notch enemy agent. 

Two, to locate the missing fiancee of a Texas oil millionaire.

Somehow they were connected. Matt did not know how, until a few members of the international set also disappeared near the infamous Bermuda Triangle. Everyone figured they were dead. Then Matt discovered they were alive, and part of a very deadly game.
