Some people who take in interest in genealogy discover that they are Irish when they thought they were Scottish. Others find a long-lost cousin. When Craig Calcaterra began looking at his family history he found out that his great-great grandmother murdered his great-great grandfather with an axe on a snowy winter's night in Detroit, Michigan in 1910. Nellie Kniffen's violent rampage and her husband Frank's grisly demise was front page news in Detroit for several weeks, but she and her crime were soon forgotten, both by the public and by her family. Those who remembered it tried hard to forget it and those who came after knew nothing about it at all.Through research of public records, personal interviews and a review of the sensationalistic newspaper stories written before Frank Kniffen's body grew cold, Calcaterra unearths a chapter which had been torn out of his family's history. And begins to better understand the ghosts and demons which have haunted his family for over a century.
