1.Bg4!  (2.Qe1#)

1...fxg4 2.Qa1      (3.Qh8#)
                Rxa1 3.Rc7  &   4.Rh7#
                Rb2  3.Qxb2 &   4.Qh8#
1...fxe3 2.Qe1+ Kxg4 3.Qg3+ Kh5     4.Qh3#
1...Ra1  2.Qxa1     (3.Qh8,Qe1#)
                fxe3 3.Rg2  &   4.Qh8,Qe1#
         2.Qb2      (3.Qh8#)
                fxe3 3.Rg2 &    4.Qh8#

I seem to remember this is a version of an old 19th Century problem that was unsound. The dual is very unfortunate, but I couldn’t see any way of eliminating it.
