Helpmate in 3 that I can't solve and it's rendering me semi-insane

If you don't know what a helpmate is, essentially, both sides collaborate to get Black mated by White's third move (Black moves first, then White, then Black, then White, then Black and then White mates.

There must be some expert composed-problem solver on here that can spare me from my misery and impending insanity (I've been working on this on and off all day)

EDIT : or if someone has an engine that has a helpmate function, that's good too

bump?

I can see a mate on white's 4th move... not the 3rd. 1... Ke6 2. Kd3, Kd5 3. Rc4, Qe6 4. Rc1, Rd6 5. Rxc5# obviously very silly moves.. 

Yeah I found a few four-movers, but 3 is killing me 

No clue. Maybe it's a double check?

EDIT: No, the Ra2 pretty much prevents that.

Double check is possible with a screen.

As a bonus, I did some searching and found there's a twin. Bc5->Bb6, other pieces unchanged; helpmate in 3 again. :D

If the bishop's on b6 instead of e7, then black has Ke7.

if anyones interested, this little program can solve mate inx, helpmate, selfmate and more.

on their page you can also find a huuuuuuge collection of problems

Which is why the position with Bb6 has a different helpmate solution. Good luck.

Thanks so much guys! :D
