It's the birthday of Barbara Callahan, born September 20, 1934 in Philadelphia, Pennsylvania. After graduating college she became a teacher and later a technical writer. Most of her energy went into raising a family (she had five children). But she began to write in the spare time she could find.
Her contribution to the mystery genre was small in quantity, but not quality. She published 22 short stories during her life. Many of them appeared in Ellery Queen's Mystery Magazine. She's recognized as an important contributor to the mystery genre now known as Domestic Suspense.
Her second story, Lavender Lady, was nominated for an Edgar Award by the Mystery Writers of America. It was published in EQMM in April 1976. The haunting tale made such an impression on editor Sarah Weinman that she included it in her 2013 anthology Troubled Daughters, Twisted Wives.
My Mother's Keeper, also published in EQMM, was published in 2009 and nominated posthumously for a Barry Award the following year. It was the last story published before her death. You can read it here.
