Sequel to: Killer instinct.

When the son of the founder of the world's largest hedge fund is thought to have committed suicide, but a body hasn't been found, his father, believing that he is still alive, turns to Dylan Reinhart for help, drawing him into a world of multi-million-dollar secrets and danger.

Everyone is surprised when Carter von Oehson, a sophomore in Dr. Dylan Reinhart's Abnormal Psychology class, posts on Instagram that he plans to kill himself. Twenty-four hours later no one has seen him, and the only person convinced Carter is still alive is his father, Mathias von Oehson. What Mathias knows and how he knows it would ultimately reveal a secret so damaging that it would be as if he were committing suicide himself. Reinhart now finds himself wrapped up in multi-million-dollar secrets-- and danger. It is going to take every bit of his wit to stay ahead of his enemy. -- adapted from back cover
