The Case of the Weird Sisters

MacDougal Duff leads the investigation into a complex case involving three blind sisters and their deceased father's fortune in this 1943 mystery novel. The sisters, each blind in a different way, live together in their family mansion where suspicious events begin to occur. The story centers on Alice Brennan, who arrives at the sisters' home to marry the youngest brother of the family. She becomes entangled in dark family dynamics and must navigate increasingly dangerous circumstances while trying to understand the true nature of the sisters' relationships. Amateur detective MacDougal Duff works to unravel the intricate connections between family members, inheritance, and potential motives as tension builds within the isolated mansion setting. The plot features elements of both psychological suspense and classic mystery traditions. The novel explores themes of perception, family loyalty, and the ways disability can be both a limitation and a source of unexpected power.

Readers appreciate Armstrong's intricate plotting and the unique premise of three blind sisters as suspects. The atmospheric family mansion setting and mounting tension draw praise. Several reviews note the clever use of each sister's specific disability (one deaf, one blind, one unable to speak) in constructing the mystery. Common criticisms focus on the slow pacing in the first third of the book and what some call an anticlimactic ending. A few readers found the portrayal of disabilities dated and problematic by modern standards.
