Well run, don't walk, and read "The Boy Who Only Lived Twice"! It's amazing. Really one of the best HD fics I've read. It's espionage for sure, though I don't think it counts as AU - it's compliant with all the books except the epilogue, and magic is used.

And you've managed to rec the one and only HD fic by lauren that I haven't yet read! I have this on my to-read list, and just haven't yet had the chance to read it. Looking forward to it!
