A #1 New York Times Bestselling Author
When Penny Dahl calls the Finders Keepers detective agency for help locating her missing daughter, Holly is reluctant to accept the case. But something in Penny Dahl's desperate voice makes it impossible for Holly to turn her down. Mere blocks from where Bonnie Dahl disappeared live Professors Rodney and Emily Harris. They are married octogenarians, devoted to each other, and semi-retired lifelong academics. But they are harboring an unholy secret in the basement of their well-kept home, one that may be related to Bonnie's disappearance. And it will prove nearly impossible to discover what they are up to: they are savvy, they are patient, and they are ruthless.
