Crystal's Beau - Police Detective Renee Brown Mystery, #3

Police Detective Renee Brown is keeping Wedgewood, Minnesota safe. This time the problems are happening on Marceil Pestkey's block. Detective Brown dreads those calls. Marceil Pestkey thinks she can get partial treatment since she's Renee's mother's best friend. Ordinarily, the calls coming in to the dispatcher at night would be handled by the night duty officer. Not when Marceil Pestkey is making the call.
She asks for Detective Brown. The drunk riding a cow home in the middle of the night wasn't so hard to handle. It was the next calls that were confusing. One night a neighbor, Crystal Tolivar, across the street from Marceil's house reported a Peeking Tom. Others reported a stalker spending time around the Tolivar house. Marceil and her sister, Tess, watch a man they called the Raincoat man show up when Crystal wasn't home and leave before she comes home.
So who is the mysterious man Detective Brown is supposed to catch if he isn't Crystal's Beau?
