Happy to help her fellow bibliophiles, Sassy visits the local library with book donations for their annual fundraising sale. Unfortunately, the welcoming readers' haven is in turmoil as an argument erupts between an ornery patron and new staff member, Tanya Lipscombe--also known as "Tanya Trouble." She may lack people skills, but everyone is shocked when she's later found murdered in her own hot tub. The man last seen arguing with Tanya is soon arrested. But Alan Mersky, a veteran with PTSD, happens to be the brother of Sassy's former boss--and he's no murderer. Now it's up to Sassy and Bridgy to clear Alan's name and make sure the real killer gets booked.
