The Mayan secrets

Will not win a Booker Prize
The Mayan Secrets is a Fargo adventure novel, co-written with Thomas Perry. It is the fifth book of the series, but can be read as a stand-alone tale. The plot sees husband-and-wife team Sam and Remi Fargo in Mexico. They appear to lots of money and don't worry about day jobs. Not only that but they spend months away from home travelling on a whim. Anyway, while in Mexico they come upon a remarkable discovery. This is the skeleton of a man clutching an ancient sealed pot. Within the pot, a Mayan codex, larger than anyone has ever seen. The codex contains astonishing information about the Mayans, their cities, and mankind itself. The secrets are so powerful that some people would do anything to own them. This leads to:

the inevitable bad guys,
explosions,
close calls with death,
treasure hunting,
fighting,
shooting, etc.

All quite formulaic, with a sprinkling of history. The characters lack any depth. There are lots of filler details the majority of which should have been cut to speed up the plot. Do we need to know what they packed, ate, drank and other trivial matters? I got to the end, because I didn't overthink it. This is literary junk food.
