Charlie and Diesel along with Charlie's fiancée, Helen Louise Brady, are heading to Asheville, North Carolina to spend a week at a boutique hotel and participate in a gathering of a mystery reader's club composed of patrons of the Athena Public Library. In addition to seeing the local sights, the members will take turns giving talks on their favorite authors.
The always spry Ducote sisters, friends of the hotel’s owners, are helping underwrite the expenses, and they’ve insisted that Charlie, Helen, and Diesel join them. Anxious to get Helen Louise away from her bistro for a vacation, Charlie readily agrees. While Charlie is looking forward to relaxing with Helen Louise and Diesel, other members of the group have ulterior motives including a long-standing score to settle.
When an intrusive, uninvited guest turns up dead, only one mystery club member with a connection to the deceased appears to have a motive to kill. But could the answer really be that simple? Charlie and Diesel, along with the detecting Ducote sisters, know that every murder plot has an unexpected twist.
