Now here’s a way to pad an issue… Tom Mandrake illustrates a flashback (with a far more traditional–read recognizable–Holmes). It’s Holmes and Moriarty at Reichenbach Falls with a different conclusion–Moriarty has zombie juice ready to save him after he… ahem… falls. It’s one heck of a way to waste pages. The artwork’s lovely and all but it’s not narratively important. In fact, it’d have been a lot more effective in the first issue without it being clear it was Moriarty.
The rest of the issue is just bridging material, presumably, to set up the climax of the series. There’s finally a big zombie battle in London, but we only get to see a little bit of it, with Moriarty (the zombie) showing it to his sidekick (and the reader) through a window.
Then tanks show up to save Holmes and Watson (and Mrs. Hudson) and it’s silly.
