Subject: Mate in 2? 3?

One of my friends tried my program on this 'Mate in 2' from John Thursby's 75
mate in 2 problems.

FEN 8/8/3PQ3/2p2r2/2N2R2/2k2N2/3RK3/8/ w - -

My program didn't see it, supplying a mate in 3 line (my email program crashed
and I lost the message.) Crafty also gave a mate in 3 line, 1. Qe3+ Kb4 2. Rb2+
Ka4 3. Qa8#.

I responded with this, and he said no! It is still mate in 2, and supplied this
line: 1.Na5! {threatens Rc4# or Qe3#  or Qc4# or Qb3#} 1 ... Rxf4 2. Qb3#

I have not had time to check on it... is it mate in 3 or 2?

P.S. He also supplied this funny mate in 2 links:
