This book explores the practical applications of mathematics in solving real-world crimes. Drawing on the popular CBS television series Numb3rs, authors Keith Devlin and Gary Lorden, both deeply involved with the show's mathematical accuracy, demonstrate how advanced mathematical concepts are employed by law enforcement agencies. They cover a wide range of applications, from forensic analysis and counterterrorism to image enhancement and even casino security, illustrating complex ideas with compelling case studies.

The book is presented as a companion to the hit CBS crime series Numb3rs, aiming to bridge the gap between fictional portrayals and real-world applications of mathematics. The authors, Keith Devlin and Gary Lorden, are positioned as experts in their respective fields, lending authority to the explanations of mathematical techniques used in criminal investigations. The content is designed to showcase how advanced mathematics can be a powerful tool in state-of-the-art criminal investigations, appealing to fans of the show and those interested in the intersection of math and crime.
