Spectrum

Karen Vail is no ordinary FBI agent. She's a profiler, brought to life by Alan Jacobson's seven years of unprecedented access to the FBI's Behavioral Analysis Unit. The character who's captivated readers worldwide and won raves from literary giants Michael Connelly, James Patterson, and Nelson DeMille returns in Spectrum, a thriller that captures the life and death experiences that shaped the revered profiler and made her the cop we've come to love.

It's 1995, the NYPD has just graduated a promising new patrol officer named Karen Vail--and the rookie cop is immediately put to the test: A young woman has been murdered. There are no forensics. No witnesses. And the manner in which she was killed is unlike any the department has seen before. The offender shows no signs of stopping, however, and over the ensuing nineteen years, the case that becomes known as "Hades" takes many unexpected twists and turns--as does Vail's career. Now a skilled FBI profiler, will she be in a better position to catch a killer who has terrorized New York City for three decades? Or will Hades prove to Karen's Vail's hell on earth?
