The Cloister Scandal at Wexford College — the Crewe file

A priceless old book vanished from the college library the night of the founder's feast, and the night porter's keys went with it. Each professor turned in for the night in a separate room along the old stone corridor. Reconstruct that night, room by room, before the college calls a hearing. The file names 5 professors; Provost Crewe's statement sits on top of the pile.
