An evil old couple is kidnapping people and imprisoning htme in their basement, but to what gruesome end? Holly Gibney is hired by a desperate mother to find her missing adult daughter. Her partner is sick, her mother just died of covid, and she has distinct hypochondriac tendencies - but it probably ain't hypochondria when the pandemic is really out to get you. Holly tenaciously follows the trail while the old couple do their evil thing.

It's nice that we've got past the point where every King was a massive bloated thing that could have done with heavy editing to shorter, solid, highly readable thrillers and shockers like this, still easily capable of giving us a slice of US life and culture with all the added thrills and chills. 

Also between covid and the old people feeding off the young, I think I detect a wee political subtext. Just a wee one.
