This one feels like an early climax for the series.
This time, the villain is so threatening that even the Russians are working with the USA to bring him down. In a rare moment of continuity, the CIA agent from the previous book "Chinese Conspiracy" even makes an appearance.
Most of the book contains The Death Merchant and his Russian allies blowing stuff up in one overlong set piece after another.
The setting is a stand-in for Haiti. For some reason, the name of the country is "Bonheur" in the book (happiness in French according to google translate). The setting perhaps outstays it's welcome a little by the end, but is quite vivid.
Politically sensitive readers will wince as the Death Merchant "successfully" disguises himself as a black person with makeup to infiltrate in one of the early scenes. There are also plenty of racial slurs.
Most of the plot is Richard Camellion (the DM) working with the Russians at the same time as knowing they will betray him at some point.
