After 26 years of research, revisions, twists, turns, dead ends, deadheads, and psychic visions, this captivating, unsolved murder mystery about a lost Grateful Dead fan is now a book. Ripple published on April 5, 2022, coinciding with the 40th anniversary year of the disappearance of Frank McGonigle, who left his Kansas City home in 1982 and never returned. His large Irish-Catholic family searched nine years for him, only to learn of his murder in a gritty South Carolina fishing village. Follow along as Cosgrove shares the rippling effects of this decade-old case. With the help of a cast of salty characters, Cosgrove uncovers connections to a ruthless local crime boss and miscues from a threadbare sheriff’s department. A chance meeting with a soft-hearted psychic who provided freakishly accurate details about Frank’s death put Cosgrove face to face with the alleged killer.

What Readers Are Saying

Barnes & Noble Customer

…It was well handled by the author with much sensitivity to the family of the victim, as the author was a family friend who grew up in that same area. Even the paranormal aspect of this case was believably expressed, which I found quite compelling. A well written true crime book that’s not your typical formula.

Rating: 5 out of 5.

The author’s open-mindedness to spirituality gives this story a unique twist to other true crime type novels and as a Dead fan could relate to the victim, a few parts gave me goose bumps. I recommend.”
