Warning: Do not click on any of the following links if you don't want spoilers, or DC-generated rumors that look like spoilers. On the other hand, I'm pretty sure it will be impossible to avoid this for a few weeks.
Haven't been following the sometimes beautifully written, sometimes baffling-to-a-nongeek-like-me Batman RIP too closely lately since the first couple of issues, but a friend just passed this along. Surprised I haven't seen word of it in the comics blogs I visit the most often (see sidebar to the right), but maybe that's because everyone's been too busy eating turkey and passing out. I'm sure the world will be abuzz shortly... This is the sort of thing that gets the mainstream news all hot and bothered about comics (at least to the point of running brief what-will-they-think-of-next stories every couple of years--see also: Captain America, Death of; Superman, Death of; Spider-Man, Unmasking of).
For the record, assuming there is more to this than the Old Switcheroo, the villain in me loves the sheer sacrilege suggested in who the killer claims to be, and the resulting implication that our hero's entire quest has been wrong-headed. That's the kind of deconstruction/mindfuck I can really get behind.
UPDATE! Speculation, plus a couple of news stories that repeat the same skimpy info as above, here.
Grimly funny column from Fake Mitch McConnell - Mitch McConnell is the Republican leader who drafted the so-called "Trumpcare" bill in secrecy and hopes to ram it into law in a few days of arm-twisting...
