Stephen King - Holly

We continue our reading of the Bill Hodges/Holly Gibney series!
When Penny Dahl calls the Finders Keepers detective agency, hoping for help locating her missing daughter, Holly Gibney is reluctant to accept the case. But something in Penny’s desperate voice makes it impossible to turn her down.
Meanwhile, mere blocks from where Bonnie Dahl disappeared live Professors Rodney and Emily Harris: married octogenarians, devoted to each other, and semi-retired lifelong academics. But they also harbor a shocking, unholy secret in the basement of their well-kept, book-lined home, one that may be related to Bonnie’s disappearance. Now Holly must summon all of her formidable talents to outthink and outmaneuver these unimaginably depraved and brilliantly disguised adversaries.
