William begins teaching at a university, and is invited to dinner at the home of the Viscount of Belfor. He and his brothers receive a tour of the viscount’s well-kept conservatory, but are taken aback by what they hear of the gardener and his wife.

William learns that Lucian, one of his students at Durhnam University, hasn’t returned for three days. What’s more, the waitress Lucian had vowed to love throws herself from a bridge and dies. However, one of the university’s administrator assures William there’s nothing to worry about, but William disagrees and begins to investigate Lucian’s last movements.
