Underboss storyline is really when Bendis digs deep into Daredevil and begins his stellar run.

It starts off with the "death" of kingpin. No spoiler, this happens the first 5-6 pages, but we all know the big bad fatty ain't about to go down that easy. But after those events we are then sent on a sprawling event of weeks and months of planning, backstabbing, learning who Daredevil really is, and how one mobster thinks he's brave enough to not only take down the kingpin but kill Matt Murdock.

This is Mafia heavy, with alot of planning and scheming but it wroks well because daredevil when dark and gritty works well. There's a excellent silent issue where Daredevil is being hunted by a bunch of hitman, it's exciting and brutal all at once with some great fight scenes. One of my favorite issues ever to be honest.

I'm loving my re-read of Bendis run but this is one of the best starting stories of any run to really get you invested into the character and the worldbuilding of Hell's Kitchen.
