Economic theories can predict many things–just not the death of a renowned Economics professor. When Professor Edmund de Beyer is found in his office strangled to death by his own PhD hood, the police don’t have to look any further than his colleagues in the Economics Department for suspects. After all, Edmund was the most despised faculty member in the department. CJ Whitmore, the department’s only tenured female (who also has a penchant for wearing pink-cowboy-boots to class), resolves to get to the bottom of the mystery using economic principles. Comparing tracking down murder suspects to selecting a used car, she attempts to discern the real deals from the lemons. That is, which suspects are really telling the truth and which are lying to protect their guilt? Will CJ be able to pick the lemon before her clever adversary strike again?
