In the Woods

He never saw them again. Their bodies were never found, and Adam himself was discovered with his back pressed against an oak tree and his shoes filled with blood. He had no memory of what had happened. Twenty years later Adam - now using his middle name of Rob - is a detective with the Dublin police force. His colleagues don't know about his past. He works as a team with Cassie Maddox, a smart, tough cookie; they are best friends as well as partners. When the body of a young girl is found at the site of an archaeological dig, Rob and Cassie get the case. And when they reach the crime scene, Rob realises it is the exact site of his childhood trauma. They also find a hairclip that he recognises as having belonged to his friend. Could there be a connection between that old, unsolved crime and this?
