From here it gets a little murky
9. Ne6 c6 10. ??? Qd4 Qa5+ 11. Bd2 Q anywhere? 12. Nxc7 forking King and Rook.
Certainly it gets pretty nasty for black but I don't think this is quite best....
In your line after 9. Ne6 then 9. .. Nb6 looks even better. It also attacks queen, but at the same time the bishop controls e6 again preventing the move repetition by Ng7+/Ne6+. If White doesn't have this forced draw anymore, Black is already better (a piece up for a pawn).
But now, since White has to win, I'm not sure if 8. Qd5+ or already 7. Qh5+ was a mistake. I'm thinking maybe 7. Ne6 is good. But I only see that Black can't take the knight because of 8. Qd5+ Kf6 9. Qf5 mate. But the other variations are kind of complex. This knight move looks more promising though, since Black cannot counterattack White's queen. I will look at it again when I'm less tired 😴

edit: but 8. ... Qf8 might refute this.
7. Bxf7+ Kxf7 8. Ne6 Qf8 9. Nxc7 looks crushing for White.
e.g. 9. ... Qf8 10. Qh5+ g6 11. Qd5+ Kf6 12. Bg5+ and White picks up the queen with a knight fork.
Originally posted by Shinidoki seeing as nobody has got it yet I'll give you all a hint:
think very hard about whites secound move of the combination.
once you find it, everything else will fall in place.
The second move (after 6.Bxf7+ Kxf7) must be 7.Ne6!, immediately attacking the queen. Kxe6 fails after Qd5+ and Qf5#. Black only has Qe8 to save the queen. Then follows 8.Nxc7, attacking the queen again. After Qf8 (Qd8? then Qd5+ followed by Ne6+ - note the check making Nb6 impossible - wins) 9.Qh5+ g6 10.Qd5+ Kf6 (Kg7 then immediately Ne6+ forks) 11.Bg5+ Kg7 12.Ne6+ wins the queen
