Detroit News, May 29, 1931. The hausfrau or boardinghouse mistress with a secret penchant for murder-for-profit is an enduring American phenomenon. Before Mrs. Summers there was Belle Gunness. Since then we’ve had Dorothea Puente and the deadly septuagenarian partnership of Helen Golay and Olga Rutterschmidt . God knows how many others have joined Margaret Summers in historical oblivion. It’s rank sexism if you ask me.
