Len Wein, Ernie Chan and Dick Giordano bring the Bat-Murderer saga to a spectacular finale in Detective 448 (June 1975), in a full-length story.
Batman gets Jack Ryder to do some legwork for him, and he informs Batman that he has traced a connection between the League’s shooter, from the last issue, and a circus just outside Gotham. He offers to help Batman investigate the circus, but Batman insists he will handle it on his own.
In disguise, Batman goes to check out the circus. It’s not too hard to guess that the snake charmer woman might be Talia, but there is another, subtle yet effective, clue on this page.
Batman sticks around after the circus closes. Sure enough, the snake charmer turns out to be Talia, who explains that the reason for framing him was to destroy his Gotham life, as they still wish him to join the League.
Batman is no more inclined to join them than last time, and as the fight ensues, the clown reveals himself to also be in disguise. It’s the Creeper, who figured Batman needed help whether he wanted it or not. And though the Creeper believes the ringmaster to be Ra’s Al Ghul, Batman has spotted the discrepancy in the midget strongman’s shadow, and has figured out that he is really Al Ghul.
By all means, scroll back up and check out that page again for the shadow clue.
As Commissioner Gordon and the police arrive, the Creeper runs off. Batman tries to leave as well, but Gordon picks up a gun and shoots Batman in the back.
The only real drawback to this story is the resolution and explanation, with the gun that points and shoots itself, and burns out the mechanism that causes this. The faking of the death certificates is well with the League’s normal range of abilities, but the gun is a bit much.
The Creeper next appears, in a couple of months, in the Joker’s short lived comic. Talia pops up a few months later in the pages of Black Lightning, but Ra’s Al Ghul has to wait until a couple more years, returning as the judge in the “Where Were You the Night Batman Was Killed?” storyline in Batman. The next big plot they are involved in is not until the 80s.
