One idea could be that there's a new dark force emerging that is using both magic and Muggle technology in a devious way. Harry, with his magical abilities, and Fornell, with his understanding of Muggle law enforcement, team up. They might start off not trusting each other fully, but as they face various challenges together, they learn to rely on one another's strengths. Fornell could be introduced to the magical world's rules and Harry could learn about Muggle detective methods. They could then use this combined knowledge to track down the source of the new threat.
