Mexico City, 1954. Gunner Quinn is drinking his life away, playing jazz in a sleazy nightclub, smuggling antiquities on the side, women just a parade of half-remembered names and faces.  Then he makes one careless mistake and is blackmailed by the CIA, plunging into an untamed jungle in search of a forgotten, haunted Mayan temple and the deadly forces that lurk within. What secrets is a beautiful government agent hiding from Gunner? Can he stop the ancient evil unleashed when a door is left open after moonrise?

From The Red Jade Door:

The green light was here already. This was the earliest it had ever come.

It moved between the trees in the jungle, irregular in shape and shifting in size. At times it was as big as a horse, others as small as a firefly. As it moved behind trees then re-emerged, it seemed to blink. Or wink, even, since it seemed always to move with some purpose. But it always stayed back in the jungle, never emerging onto the beach or taking wing to soar over the treetops.

“My God, it’s not even dark yet,” the Lieutenant said.
