Find Me When I’m Lost by Cheryl A. Head

Shortlisted for the 2021 Lambda Literary Award in LGBTQ Mystery. When Charlie Mack is hired by her ex-husband's new wife Pamela, things get awkward quickly. Her ex, Franklin, has been charged with his brother-in-law's murder. Charlie and Pamela both believe he didn't do it, but he's gone into hiding for some reason neither of them understands. To the police, it adds up to easy guilt, but to Charlie, it indicates that Franklin has stumbled onto something that likely comes with life-threatening complications. Charlie wants proof the case doesn't involve a double-cross, and when the Mack Investigations team throws all their assets at the case, Charlie's girlfriend, Mandy begins to worry that Charlie's all-out efforts to find Franklin might be driven by lingering romantic feelings. In the end, everyone involved must figure out which loyalties run deeper than love.
