Puzzle and the "en passant rule"

Let me begin with some explanation. The en passant rule's definition is : "a special pawn capture that can only occur immediately after a pawn makes a move of two squares from its starting square" as stated by its Wikipedia page (https://en.wikipedia.org/wiki/En_passant)

Now there is something really simple with the en passant rule that I have completely overlooked and I feel everybody should know about, if it is not already the case : The en passant rule states that "the captured pawn must be on an adjacent file".

And this is something I've completely overlooked. I just learnt of it because of this particular puzzle ! It is black to move here. Hint : en passant rule.

It's just e5 forking the knight and queen.  What does en passant have to do with it?

Oh I get it; you thought you couldn't do that because of en passant....Yeah I can see how that might be confusing.

I was weirded out by the fact that I thought the en passant rule would apply here. I never learnt of the idea that if the pawns aren't on adjacent files when the pawns advances two squares you cannot take it with the en passant rule. 

Part of being a beginner !

That's OK, lot of confusion around the rule.  Here's an article for any beginners still a little unclear.  Oh and there's a link in the article for a step by step that's even more basic...
