I think the move is Rxc4, because if it\'s taken by the pawn then Nf3+ opens up the pawns in front of the king and the light squared bishop and queen can come in to checkmate. I am not sure if white can get out of it by declining to take the Rook though...
(hidden fixed so it displays properly)
Edit: morgski - in hiddens replace all ' with \' to make it work.
I don\'t see the need for Rxc4, as I can\'t see a defence for white after Nf3+ followed by Bh3
