When Drew's little brother Martin digs up a bone in the back garden, Drew isn't worried at first.

He thinks it's just a dog's bone. But when Martin finds more bones, he realizes they make a hand.

To begin with it feels like an adventure, but then the bones seem to move from where Drew leaves them, and someone is writing him spooky messages...It turns out there is a body of a soldier from the Civil War buried in Drew's back garden, but the hand is from someone smaller, a soldier boy who won't rest until Drew and Martin bury his bones again.
