The Devil's Cook — Ellery Queen

A killer stalks a college campus, sending the co-eds scurrying

Terry Miles goes across the hallway expecting an orgy. When her neighbor opens his door, she finds that the promised erotic party is nothing more than a few brainy academics balancing beers on their bellies and arguing about philosophy. She's disappointed, but not surprised. Nothing ever happens at Handclasp, the most wholesome university in the most commonplace city in the United States. Nothing, that is, but murder.
 
When Miles disappears, Police Captain Bartholdi isn't sure if she was kidnapped, murdered -- or both. As the local cops mount a frantic search for the missing beauty, Bartholdi tries to unravel a case that hinges on a husband who doesn't miss his vanished wife, a university full of suspects, and a ragout that's overflowing with onions.
