The theme seems fairly clear (Qa3-b2 mate), but the calculation of the lines
requires some precision. I'm still on my first coffee, but will try this without
an engine for the heck of it. Hope the lack of engine doesn't make it off-topic,
or the lack of sufficient caffeine make my answer somewhat loony :-P
1...Qa5 (I thought of Qb4, but think that provoking a4 is important in lines
where white tries the usual Ka1-Rb1 to defend) 2.Qxd6 Rc5! and here I think
White's best reply is probably 3.Rf3 as it allows 3...Qa3? 4.Bh7+ Kxh7 5.Rxc3
and the Black rook is pinned. So probably 3...Bxa4 with the idea of Bb3 or Bb5
(threatening a5-a4). That's as good as this half awake brain is going to do.
Let's see what I missed now.
