8 Mysteries Even Batman Couldn't Solve
3. He Couldn't Save Alfred - City Of Bane
Not a mystery in the same sense of one of the Riddler's infamous riddles or in the same sense as the secret identity of a new rogue, but here it was more Batman fell foul of a conundrum. And by fell foul, that shockingly meant the very real, very permanent (at least so far) death of Alfred Pennyworth.
The puzzle presented to the Caped Crusader here was that if the Bat-family remained in Gotham, Alfred would be murdered.
So, Bruce Wayne headed off to Paris with Selina Kyle, while the rest of our heroes all kept out of sight. As for who had made this threat, that was the Flashpoint timeline's Thomas Wayne, aka that world's iteration of Batman. With Bane at his side, Thomas had taken over Gotham City, handed Bruce a beating, and threatened to take the life of Alfred should any heroes refuse to leave Gotham.
For our regular Batman, readers saw him ponder how he could 'win', how he could return to Gotham yet keep Pennyworth safe. That was the mystery, that was the puzzle, that was the poser - all while Bruce contemplated retiring for a quiet life with Selina.
It would be Alfred who forced Batman's hand here, sending him a coded message to assure Bats that he'd managed to escape and get himself out of Gotham. Of course, he hadn't, and the resurfacing of Damian Wayne's Robin in Gotham resulted in Bane snapping the neck of Alfred - which the iconic butler had intended to happen, so that it would give Batman the motivation to return and take down these rogues.
