U is for undertow - Sue Grafton (Kinsey Millhone #21)

"When I was a little kid, I was playing in the woods and I came across two guys digging a hole. I remember seeing a bundle on the ground a few feet away... now I believe it was Mary Claire’s body, and they were burying her."

In 1960s Santa Teresa, California, a child is kidnapped and never returned.

Twenty years later, Michael Sutton contacts private detective Kinsey Millhone for help. He claims to have recalled a strange and disturbing memory that just might provide the key to the mystery. He believes he stumbled across the kidnappers burying Mary Claire Fitzhugh’s body.

Michael’s account is indistinct—he was only six years old at the time of the kidnapping—and even members of his family try to discredit his evidence.
