Campus Casualty by Marcia Dove

Maggie's excitement about moving into her new office on the PSU Campus is short-lived when her nemesis, Dr. Harrison, picks a fight with her when she arrives to collect the key. Frustrated and fed up with Harrison's bullying, she threatens to report him, further inciting him; his shouting attracts a gathering crowd. The troubling realization that Dr. Harrison's office is located across the hall from hers becomes problematic when she finds Harrison dead in his office the day after their altercation — her sketchy alibi is sure to place her on the top of the detective's suspect list.
