The Secret of Annexe 3 — Colin Dexter

WHO HOLDS THE KEY TO A HOTEL ROOM? AN AMOROUS STRANGER? A DANGEROUS LOVER?

A West Indian Rastafarian costume won him first place at the Haworth Hotel's New Year's Eve ball. But when his body is found in Room 3 of the hotel's annexe, no one knows his real identity or that of his missing "wife." And no one knows why the annexe's four other registered guests have vanished. Except Inspector Morse. He knows the basest of human desires will flourish behind a mask. They have in Annexe 3. Illicit love. Greed. And, of course, murder.

Chief Inspector Morse, Homicide Division, Oxford: A lonely middle-aged bachelor with a taste for Mozart and T.S. Eliot, pints of bitter--and an obsession with attractive women. As coarse as he is cunning, at times insufferable, relentlessly inquisitive.
