DIABLO MESA

Two desiccated corpses aren’t the strangest discoveries made by archaeologists in this third entry of Preston and Child’s unusual crime series.

Nora Kelly is summoned to her boss’s office at the Santa Fe Archaeological Institute and assigned to investigate the site where an unidentified aircraft, perhaps a UFO, supposedly crashed in 1947. She believes that claims of an alien space landing near Roswell are “wacko.” But billionaire Lucas Tappan has provided a generous grant to the institute, and he specifically wants Nora to lead the expedition because of her reputation. She declines and is fired. So Tappan comes to her directly. But “I can’t put digging up UFOs on my resume,” she tells Skip, her less-skeptical brother. “It’s too weird.” Tappan wears her down and hires them both. Reluctantly she takes a team to the area, where they uncover a pair of corpses buried in New Mexico’s high desert. They notify the police, and FBI agent Corrie Swanson takes on the case because they’re on federal land. But the depression in the sand suggests that the vehicle—a flying saucer, maybe?—had struck the ground at a low angle and skipped repeatedly, like a flat rock across a pond. When they come to a possible final resting place, the archaeologists start digging. Just as they are about to make a shocking discovery, armed men stop them. Whatever is under a couple of meters of earth is a secret the government has closely guarded since the ’40s, and these dudes demonstrate that they will kill intruders on the spot. Kelly and Swanson aren’t friends, but they’ve worked well together ever since they debuted in Old Bones (2019), and they are smart, strong, and appealing protagonists. The story has tension, mystery, murder, and enough romance to give Kelly “a powerful glow, a whole-body tingle.”

Down-to-earth action tackles an otherworldly mystery in this devilishly plausible yarn.
