He teaches business at the university his ex's family bankrolls, a fallen tycoon rebuilding a life one lecture at a time. His ex is student council president, back for a second degree, and wants him gone. Their reunion is a war of barbed flirting across a lecture hall, until a best friend turns up dead and an alibi is needed fast. Thirty chapters of interrogations, anonymous threats, gunshots in a corridor, a charity ball that goes dark, and a case that closes with no suspect named.
