Cassie and Rob are hard at work cracking a murder case.
Okay, actually they're playing Worms on his computer.
They are the only people in the office when O'Kelly, the chief, barges in with a case: a murder in Knocknaree. Archeologists found the body.
This is the first time Rob has been to Knocknaree since the incident in the woods. (Warning: We're going to try and say in the woods as much as possible during this summary.)
Rob and Cassie ride out there to see the body… wait for it… in the woods.
Dr. Hunt, the site director, passes them off to Mark, a guy who often does tours of the site.
Mark tells them that they found a Neolithic settlement in the woods, and other artifacts from almost a thousand years ago.
Despite the finds, the government is going to bulldoze the site for a motorway in a month.
He leads them to the body, which has been placed on a ceremonial stone.
For a second, Rob thinks it's Jamie, his friend who disappeared, ahem, in the woods twenty years ago.
It's not. This girl has only been dead a day.
Sophie, the crime-scene tech, gives them the rundown: ten to thirteen years old; head smashed in; ligature marks on the neck; probably raped; probably killed somewhere else, then dumped; there's a bloody rock nearby.
There's also a red hairclip shaped like a strawberry nearby, but it doesn't seem to be this girl's. Who could it belong to? Rob thinks he knows…
