A nice composition, where its solution includes both a sacrifice and a check by discovery.
SPOILER follows:
White should sacrifice the rook at G7 by taking the pawn at H7, which forces the king to take the rook. White follows by checking with the queen at H5, which forces the king to G7. Now white checks with the bishop at H6, which allows the king to retret to either H7 or H8. In any case, white closes the deal by discovery: bishop to F8. Checkmate.
