The problem is that there is a good chance that behind the inner brick of the fireplace there is enough space for the squirrel to get stuck, but not enough for it to turn around or to back out. I don't know how your fireplace is made, but perhaps calling a store that install fireplaces and asking about how to remove the back wall of brick (sometimes it's just a fireproof facade that can be removed and replaced) or asking their recommendation to getting an animal out from behind the firewall. You may also be able to just cut into one of the bricks in the back of the fireplace, but that's tricky and can be dangerous to the squirrel if it's stuck right where you're cutting the brick.
Anther option may be: Do you have an attic/crawl space where the chimney goes through? Sometime there are gaps around the brick and/or you can pull up the floor boards behind or to the side of the fireplace and then put a long, medium sized hemp rope down the hole so it goes the length of the fireplace and hope the squirrel can get to it and climb up into the crawl space where it can be captured.
The siding of the house could be carefully cut and removed to be easily replaced and see if more lights aids the squirrel in coming back out the opening. The problem is that this may be a mother with babies and she will not want to leave them.
If you do capture it, you will need to see if it needs first aid and hydration. being stuck without water is fatal.
I'd try calling around and talking with anyone that builds, sells, or otherwise deals with fireplace building/replacement and ask their advice.
I hope it comes out and brings any relatives it may have in there with it. I would definitely leave the flue open (that's the little flap that you open when having a fire going). It may have gotten in that way, strange as it seems.
Good luck! Keep us posted!
