Merl Reagle's Crossword

"The Silence of the Lampreys"
NOTE: As I recover from this year's American Crossword Puzzle Tournament, here's my puzzle from last year's event. It's a bit trickier than my usual puzzles (after all, it's a tournament), but if you use a little "sound" reasoning (ahem), you should be able to conquer it.
