Toxic Prey by John Sandford

Published by G.P. Putnam's Sons on April 9, 2024

Readers never know what they’ll get from John Sandford, but they know it will be good. Some of his crime novels are light and a little goofy. Some of his books are dark, although he often lightens the mood with humor. All of his books are quick reads, but some depend on action more than others. I’ve read a lot of Sandford’s novels, enjoyed them all, but I can’t think of one that hit me as hard as Toxic Prey. It might be his best work.

Other people have written thrillers about terrorists weaponizing viruses. They became particularly popular after COVID. Before that, novels like The Andromeda Strain (still the classic in the subgenre of outbreak novels) imagined heroic efforts to contain the natural spread of viral infections (although the virus in that novel had an extraterrestrial origin). Toxic Prey is a variation on the theme.

The virus has been engineered — the Marburg virus is married to a measles virus so that one of the world’s deadliest diseases will become much more infectious — and the person who plans to spread it isn’t a conventional terrorist. Lionel Scott is a British doctor who wants to save the world by killing most of the people who are destroying it — people who drive or use air conditioning. Yeah, I know we’re bad, but killing 80% of us seems a bit extreme.

Scott subscribes to the Gaia hypothesis (some aspects of which have a certain appeal), but his work with Doctors Without Borders has left him depressed and traumatized. Scott has been working with the US military to devise ways to make viruses more deadly. The US Army Medical Research Institute of Infectious Diseases and the Los Alamos National Laboratory (the place where Oppenheimer worked) both research deadly diseases, supposedly to protect public health. Whether they also try to weaponize viruses is, not surprisingly, a military secret.

Letty Davenport (who sort of works for Homeland Security) is sent to England to interview people who know Scott after Scott goes missing. She liaisons with Alec Hawkins of MI5. Before long they are liaising in bed. What they learn about Scott is concerning, so Letty returns to the US, where she is assigned to find him. When she acquires evidence that Scott has been experimenting with a weaponized virus, she gets Hawkins to join her and enlists the help of her father (Lucas Davenport, who stars in a series of his own), another federal Marshal who works with Lucas, and a sniper who has appeared in recent novels when people need to be killed from a distance.

Most bioterrorism novels (as opposed to natural outbreak novels) aren’t convincing. This one is both plausible and chilling. The story moves quickly from start to finish, building suspense as the good guys work out realistic strategies to find Scott and the handful of people he has recruited to his cause. All the good guys are at risk of dying from exposure to the virus. Sandford creates credible fear that they might need to sacrifice themselves to save the world.

I don’t like to use review clichés like “gripping” or “riveting,” but those are the best words to describe the emotional investment that I made in the story. The “wow” factor is undeniable. Kudos to Sandford for producing such a powerful thriller after writing more than fifty novels. Some successful writers are just coasting late in their careers. Sandford just seems to get better.
