That Lake. This house. His friends. They all know what happened to my boy. I know they do. And you... you have to help me find the truth... A weekend to remember...Ten years ago, deeply in love, I would have done anything for Thomas Kirkwood. But on the night of our graduation, fuelled by drink and drugs, Thomas's lifeless body was found floating in the Kirkwood family lake. That weekend changed everything, and I swore I would never return to Kirkwood manor. A weekend to forget... Now, ten years later, I have been invited back to the place that holds such terrible memories for me, to a memorial weekend for Thomas, organised by his still-grieving mother Ada.But this is no ordinary weekend. This is a reunion to catch a killer... and I fear that I could be top of Ada's list.
