"The murder mystery that has confounded and fascinated people for over forty years has been given a whole new life. "When Evil Came to Good Hart" is a well-researched and well-written piece of nonfiction that holds the reader in its spell, just as it has the many writers, reporters, and law officers who have puzzled over it. My highest praise for Mardi Link's book is to say that it reads like a good novel, a real page-turner."--Judith Guest, author of "Ordinary People" and "The Tarnished Eye"In this page-turning true-life whodunit, author Mardi Link details all the evidence to date. She crafts her book around police and court documents and historical and present-day statements and interviews, in addition to exploring the impact of the case on the community of Good Hart and the stigma that surrounds the popular summer getaway. Adding to both the sense of tragic history and the suspense, Link laces her tale with fascinating bits of local and Indian lore, while dozens of colorful characters enter and leave the story, spicing the narrative.During the years of investigation of the murders, officials considered hundreds of tips and leads as well as dozens of sources, among them former secretaries who worked for murder victim Dick Robison; Robison's business associates; John Norman Collins, perpetrator of the "Co-Ed Murders" that took place in Washtenaw County between 1967 and 1969; and an inmate in federal prison in Leavenworth, Kansas, who said he knew who killed the Robison family.Despite the exhaustive investigative efforts of numerous individuals, decades later the case lies tantalizingly out of reach. It is still an unsolved cold case, yielding, in Link's words, forty years worth of "dead-end leads, anonymous tips, a few hard facts, and countless cockamamie theories."
