Justice League #32 Question

At the end of Justice League no. 31 Lex Luthor shows up at Wayne Manor and kind of puts poor Alfred on the spot.

Then at the end of the next issue Batman, Supes & Wonder Woman are confirming that Lex knows Batman's secret identity.

Did I miss anything in between? Was this covered in more (well actually, any) detail in one of the other Justice League books?

It just seemed to be a bit jarring/sudden to me...

@papinacho:

Dammit! I couldn't remember the specific issue, so I went by the cover picture!

Thanks for the correction, but my question still stands. Was there an actual conversation/denial between Lex and Alfred or Bruce?

@papinacho:

Ok, thanks. Like I said before it just seemed like we'd missed a major plot point. Especially given the cover with Lex holding the Cowl.

Yes, there was a conversation between the two, and it ended with a gun being pointed at someone else. I'll let you get into that, but there is more detail and depth about this, and explanation as to how he found out.
