What are your favorite episodes from the seventh season?

These are my top 4:

"The Return of Preston Giles"
"Family Doctor"
"Who Killed J.B. Fletcher?"
"Murder, Plain and Simple"

Season 7 contained five episodes now called "bookend episodes" that only featured Jessica introducing and closing the episode.

Here are the five bookend episodes from season 7:
"See You in Court, Baby"
"The Great Twain Robbery"
"Murder in F Sharp"
"Suspicion of Murder"
"Where Have You Gone, Billy Boy"
