Add a comment to this post with your solution. I'll buy a beer for the first person to correctly solve the problem next Tuesday, during our regular session at Matchless.
Note—To win the beer, please show all possible variations.

Nice try, Ben, but this is not the solution. Black is not forced to interpose the Bishop (2…Be5 3.Rxe5#), instead 2…Kxd5 3.Bf7+ e6 4.Bxe6+ Kxd4 5.Rd1#. It's still mate, but not mate in three.

1.Qe2
1…Bxd5+ 2.Kf4+
2…Be4 3.d5#
2…Be5 3.Qxe5#
1…Rb2 2.Kd3+ Rxd2 3.Nf4#

One more critical variation in there:
1.Qe2 Rxd4+ 2.Kf3+ Re4 3.Nf4#

1.Qe2 Rxd4 2.Kf3+ Kxd5 3.Qa2#
Ugh. I’ve spent waaay too much time on this puzzle.
