Midnight Guardians: A Max Freeman Mystery (Max Freeman, 6)

Max is back, trawling the trailer parks and waterways of south Florida, where amid the gorgeous beaches and abundant foliage there lies a stunning range of brutality. After Max is hired to investigate a conspiracy involving fake claims to Medicare, he quickly realizes the scheme is much more dangerous than anyone assumed. And when the Brown Man, a former drug kingpin who once helped Max nab a serial killer, reappears in a slick new guise, Max must reclaim his street instincts to protect not just the citizens of south Florida, but also his girlfriend, Detective Sherry Richards — the one person he can’t afford to lose.
