This sixth in Child’s Jeremy Logan series pits the vaunted enigmatologist against high-tech evil. A scientist falls, with the help of an ax in his back, down a deep crevasse on an Alaskan glacier. Later, a business mogul suffers an apoplectic, bloody death in a Manhattan business meeting. Then a Beechcraft pilot fatally crashes for no obvious reason. All three are members of the board of directors for the mega-company named Chrysalis, and the connection among their sudden demises is a mystery. So the company urgently requests the assistance of Jeremy Logan, a paranormal sleuth who has at least five major successes under his belt. He drives his Lotus to a facility hidden deep in the Berkshires of Massachusetts. It’s a highly secure, secret building shaped like a torus, or doughnut. There, he meets with both techs and execs and receives complete authority to investigate—to ask any question of anyone inside the complex. Chrysalis is about to launch the newest version of its Venture product, and they are afraid that someone has programmed it to kill its users. Meanwhile, Logan is highly enamored of their current technology and already uses a virtual assistant called Pythia until his equipment is upgraded to the silken-voiced and ever so helpful Grace. “Grace, you’re a peach,” he tells her. “No, Jeremy,” she replies, “I am a virtual assistant.” It happens that the torus contains “a nest of fire ants,” and as Logan pokes and prods, people continue to die. What hath Chrysalis wrought? A killing machine? Whatever malware might drive the new device, humans amply supplement with intra-doughnut gunfights. Grace, Logan, and the dead mogul stand out among the characters, while the others make a lesser impression. Logan’s fans won’t be disappointed—and it’s an enjoyable stand-alone thriller, so it’s not necessary to read the series in order. Plenty of imagination, with a peek at plausible near-future technology. Copyright © Kirkus Reviews, used with permission.
