The Park Rapist has murdered his first victim—and FBI profiler Karen Vail is on the case. As Vail races through the streets of Washington, D.C. to chase down a promising lead that may help her catch the killer, a military-trained sniper takes aim at his target, a wealthy businessman’s son. But what brings these two unrelated offenders together is something the nation’s capital has never before experienced.

In a short story derived from the highly-praised national bestselling Karen Vail series of thrillers, Fatal Twist gives the reader a taste of the dynamic FBI profiler, who’s been called “My kind of hero” by Michael Connelly, “A hell of a lady: tough, smart, funny, and very believable” by Nelson DeMille, and “Compelling” by James Patterson.

Alan Jacobson received several years of personalized training from two senior FBI Profilers at the Behavioral Analysis Unit in Quantico. Fatal Twist, like Jacobson’s Karen Vail novels The 7th Victim, Crush, Velocity, and Inmate 1577, brings real characters to the page—and in the process takes readers on a thrilling ride that culminates in an ending that leaves them satisfied…and wanting more.


Fatal Twist is available from Amazon and Barnes and Noble.


“Karen Vail is my kind of hero.” – Michael Connelly
“Karen Vail is a knockout, tough and brilliant.” – Tess Gerritsen
“A hell of a lady…smart, funny, and very believable.” – Nelson DeMille
“Karen Vail is one tough character.” – Kathy Reichs


Alan Jacobson’s literary career has been marked by a number of events, but none more significant than an accidental meeting 20 years ago. While researching False Accusations at the crime lab, Alan met FBI supervisory special agent Mark Safarik, a profiler with the FBI Behavioral Analysis (profiling) Unit. Agent Safarik invited him out to Quantico to tour the FBI Academy, and thus began his immersion in the world of serial killers.
Seven years later, after numerous trips to the BAU, Alan’s education had reached critical mass and he started writing his third novel, the first featuring FBI Profiler Karen Vail. Vail had an explosive debut, bursting onto the scene in the national bestseller The 7th Victim. Sporting a vibrant personality oozing sharp wit and sarcasm, Vail is a woman bucking the odds in a unit geared toward men, someone who always means well but, like any human being, makes mistakes.
Vail has directed the action in The 7th Victim, Crush, Velocity, Inmate 1577—and is featured in the short story Fatal Twist. The Karen Vail novels have been optioned by TNT for a series of two hour TV movies.
Alan’s years of research and training with law enforcement—including the US Marshals Service, SWAT, Scotland Yard, the DEA, bomb squad, and the FBI—have been instrumental in shaping the stories he tells and the diverse characters that populate his novels.
