On theOther Hand, Death

Dot and Edith's happiness in their home stands in the way of their neighbors' decisions to sell to the Millpond Corporation so it can build another blight on the landscape. A campaign of intimidation, at first merely irritating, escalates to murder before PI Strachey sorts it all out and learns something about his feeling for lover Timothy Callahan.
