On the Other Hand, Death: A Donald Strachey Mystery(2008)

"America's favorite gay private eye is back."

Overview

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 that the attack is motivated by big-business rather than homophobia.
