Monte Carlo Murders: Who Stole What and Why?

Detective Kyle Cooper must solve three murders to prevent a fourth. The only thing connecting these is a bloody textbook, but what does this have to do with anything? The motive appears to be money, but none of the victims had any. The evidence leads to high-stakes illegal gambling, which doesn't fit with the lifestyle of the three dead graduate students. Unflappable medical examiner, Dr. Samantha Trout, ever-curious CSI, Stacy Lambert, plus two graduate students combine their wits to solve what can only be a mathematical problem.
