To recover his license, Drum must unlock the mystery of a professor's suicide Duncan Hadley Lord seems too happy to kill himself. But then, he has no reason to sleep around, either. For three months the history professor has carried on an affair with a call girl, and for the last few weeks Chester Drum and his partner, rookie PI Jerry Trowbridge, have watched him do it. When Lord steps onto a fourth-story window ledge on Homecoming night, Drum gets through the police cordon just in time to watch the professor fall to earth. An embittered local sheriff, convinced that Drum and his partner were blackmailing the professor, has their license revoked. To salvage his business, Drum must find the real reason for Lord's suicide. He has tangled with politicians, thieves, and spies, but no detective can truly know treachery until he steps into the hallowed halls of a college campus.
