Oh it's the other way around, ok Nf1. Rook is pinned because of Qd4#, 2.Nd3 is unstoppable..

The composer of this problem has his own website, which is well worth a visit:

I think you mean 1.Nc1, which is refuted by ...Rxe4.

Here's the solution:

1 Qd3? (threat 2 Qd5)
1 ... Rxe4 2 Qb5
but 1 ... Rh5!

1 Qa4! (threat 2 Qb5)
but 1 ... bxa3!

1 Qd1? (threat 2 Qd5)
1 ... Rh5 2 Qxh5
but 1 ... Rxe4!

1 Nc3! (threat 2 Na4)
1 ... bxa3/bxc3 2 Qb5
1 ... Rxe4 2 Qd5
