Many years ago, I heard of a series of detective books by Laura Lippman set in Baltimore. I made a mental note to check them out and then forgot about it until I saw another book she wrote in a Little Free Library. Checking Audible, I found a couple of the Tess Monaghan books. This is number 5.
A woman reaches out to Tess through her father and hires her. Her huffer brother, Henry had been in prison for accidentally killing a girl he had picked up to do drugs with. She had no ID and he didn't know her name. He was killed in prison. His sister now thinks it must have been related to his crime and wants Tess to figure out who the girl was.
Working backwards to when Henry might have met the girl, Tess finds a sad sack teenage girl who talked to her the day before she was killed. She didn't tell Suky her name, but they talked about a place called Domino's or the sugar house. Thinking it might be a dive bar type place, Tess visits the three most likely places.
Meanwhile, Tess's friend Whitney notes that the autopsy mentioned tooth damage consistent with bulimia. Sneaking into a residential clinic on the Eastern Shore, Tess meets a girl who knew the missing girl. Her name was Gwen, and she was from a wealthy dysfunctional family in Potomac, MD (close to my neck of the woods). Hating the treatment center, she had run away. Not wanting to admit failing, the treatment center waited until Gwen's 18th birthday and then told her parents she'd checked herself out, so at the time of her death she hadn't yet been reported missing.
Although it appears that there is no connection between Gwen's death and Henry's, Tess feels something isn't right and continues to investigate. She stumbles upon a sleazy corrupt political figure who has been trafficking runaways. Gwen had gotten caught up in this and found Henry as she was trying to escape from it.
Growing up in DC, sort of Baltimore adjacent, many of the places, situations, and types of people portrayed in the book are familiar. The corruption of late 20th century politics in Baltimore and Annapolis is crazy, but not unrealistic. The locals are self-deprecating and have a lack of self-esteem that rings true. The reader even got the distinctive Bawlmer accent down. Although the ending was a bit over the top, I really enjoyed the following Tess as she investigated.
