Critical reception
Reviewers saw What the Dead Know as a success both as a well-crafted mystery and as an emotionally powerful novel. The Guardian described the novel as a "realistic and poignant detailing of emotional hide-and-seek, ... an excellent mystery and a thoughtful exploration of the nature and effects of grief and loss." Kirkus Reviews praised the novel, noting that "Lippman (To the Power of Three, 2005, etc.) crafts a tale that resonates long after the last page is turned." Janet Maslin of The New York Times praised What the Dead Know as "an uncommonly clever imposter story", "three-dimensional", and worthy of reading a second time — "You read it once just to move breathlessly toward the finale. Then you revisit it to marvel at how well Ms. Lippman pulled the wool over your eyes."
