We have two creepy and unabashedly supernatural short stories for your spine-tingling pleasure this Hallowe'en season. And even though this is Christie off her regularly beaten path of logic and reason, the lessons to be gleaned from these two macabre tales are fully on brand for our beloved Dame Agatha. Beware: 1) a mother's love; and 2) a real estate bargain. [Insert banshee keen here.]
