On the Other Hand, Death: A Donald Strachey Mystery

When the residents of a neighborhood are offered huge sums of money to sell their homes to a developer, the only ones to refuse are an elderly lesbian couple. Soon after, the couple's home is besieged by anti-gay vandalism, but Don suspects the attack is motivated by big business rather than homophobia. As the investigation progresses, Tim and Don fall in love all over again, as strengthened by their admiration for the elderly lesbian couple.
