Complicated Heart (The Avery Detective Series, #4)

After closing a string of high-profile cases in Kansas, Parker and the Avery Detective Agency are ready for a fresh start. But their next assignment proves more dangerous than anything they’ve faced before. Contracted to work alongside the ATF and FBI, the team heads to Chicago to investigate a mysterious oil trafficking ring that’s targeting rural communities and exploiting local farmers.
As the team digs into the case, they uncover a growing network of organized crime, corruption, and land exploitation. Farmers are being forced off their land, oil is being stolen, and lives are being threatened. Every lead pushes them closer to a truth no one wants to face—and someone is working hard to keep buried.
But just as Parker begins to piece the puzzle together, figures from the past reappear, complicating both the investigation and personal loyalties. With the stakes rising and danger closing in, the Avery Detective Agency must stay one step ahead before the next target is one of their own.
Perfect for fans of private investigator thrillers, suspenseful crime fiction, and fast-paced mysteries, this gripping novel delivers a twist-filled ride where justice comes at a price—and the enemy might be closer than anyone realizes.
