The Ivory Tower. Bob the Caretaker, #3

The Ivory Tower is the third Bob the Caretaker novel - a taut, escalating thriller about a man with a new name, a new badge, and a fresh alias, slipping unnoticed into the halls of power. Now calling himself Daniel Mercer, Bob moves through Briarwood University as he always has: quietly, precisely, seeing what institutions hope no one sees. And when the first name goes into the basket, the tower learns what every building before it has learned - Bob doesn't clean messes.
He removes them.
