A young woman is lost on a scuba dive in Grand Cayman. Did she suffer nitrogen narcosis? Or did she commit suicide? Experts argue both scenarios in a civil trial that takes place 14 months later. Her parents are the plaintiffs. The defendants are a large corporation and its dive master on that fateful day. There are several experts called to testify, including the author. The two lawyers object to each other's arguments, cite precedent, drill their experts. Yet one thing is missing: her body. It will never be recovered. The Wall is fiction, but it reads like a real case. Put yourself in the jury box, listen to the experts and lawyers battle it out, then make your decision. How will you decide? For the plaintiffs or the defense?
