Bruce Wayne: Murderer?" is definitely a really good event when it comes to crossover events with the Bat-Family.
Basically, Bruce is put on trial and imprisoned in Blackgate, as we try to figure out if he really killed somebody. Now, as a reader, you're probably thinking there's no way Batman would ever do that. But you have to understand that in this time, after certain events with Jim Gordon, Batman is basically going slightly insane. He's turning more and more into the Batman from Dark Knight, where he's obsessed with a mission, and Bruce is essentially a facade, with the true him being Batman.
So, once you take that into account, you understand that the whole world is looking at Bruce as a murderer now, and he cannot stand it. He cannot be stuck in jail, just waiting. And while that's happening, we're on the outside, looking at all his Bat-Family members—such as Cassandra, Tim, and even Dick—who are trying to solve this mystery.
Overall, all the stories connected really well, which always makes an event good. I would have to say if there was a weak link to all this, it's definitely the Robin stories. They don't feel nearly as connected as everything else. And the Birds of Prey, while entertaining, also feel a bit disconnected at times, but luckily they're pretty solid for character work. Other than that, the main event, which is written by Ed Brubaker for Batman and Detective Comics, is absolutely fantastic and offers some really great moments for Bruce as a character. The Nightwing stuff is also pretty solid, as is the Gotham Knights material.
Overall, this is a very, very solid four out of five. If you love things more in line with Ed Brubaker's style of writing, which is kind of more detective and dark, then this is a book that you might want to check out.
