The Court of Owls

And the Court of Owls storyline might just bring that kind of suspense. In a way, the Owls and their assassins might just be the red line which connects the installments of another trilogy. The first Batman film will mean just the beginning of the storyline, with the Dark Knight discovering that there is a shadow presence in Gotham, a secret society that pulls the strings of everything happening in the city.

In a way, it can be the League of Shadows of a new Batman trilogy, with one major difference. If the Caped Crusader already knew and had connections with the League, the Court of Owls will be something new to him, making him put his detective brain to work.
