The Big Bad Wolf
James Patterson
 Dr. Alex Cross is in the middle of his training at the FBI when he is assigned to work on a kidnapping case. A federal judge's wife has been kidnapped, and Dr. Cross discovers that her kidnapping fits the pattern of other recent kidnappings. A Russian mobster known as "The Wolf" has been kidnapping people and selling them into sexual slavery. In addition to the judge's wife, his subordinates also kidnap a housewife, and several male college students for clients. Though Cross is able to identify The Wolf as a key player in the human trafficking ring, his true identity and whereabouts remain a mystery. The only method of contacting him is through a high-tech, secure website, and any person the FBI manages to take into custody ends up dead at the hands of a mole. Eventually, with the assistance of the New York City Police Department, Central Intelligence Agency, Secret Service, and the Russian government, the FBI is able to arrest a man by the name of Andrei Prokopev. Though the FBI believes him to be The Wolf, it is revealed at the very end of the novel that The Wolf is, in fact, still at large.
