Author/Opus: This is the 120th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Fill some empty cells with the letters A-F (A-D in the example) so that each row and column contains each letter exactly once. The letters outside the grid indicate the first letter seen from that direction, but each row and column has one transparent letter that is ignored by the clues. The transparent letters must be different in each row and column.
