I'm on the last level of Majestic Chess and am wondering if anyone can
help me with this puzzle:

There are white bishops on squares D5 and E5. There is a black queen
on square F2.
Challenge: Place both kings on the board so that, if it is white's
move, white will checkmate in one move.

I've come close, putting them so that white can checkmate in 2 (the
queen blocks the first check) but can't solve this darn thing!

Thanks all
