Holmes and Watson in “Unfinished Business”

Two years ago, Charles Milverton referred a client to 'The Sheriff.' His name was Abraham Zelner, a morbidly obese man who wanted to sue an airline for removing him from a flight. Zelner was the only client that Milverton referred. Earlier we were theorizing that 'HENRY8' was Milverton's accomplice. Henry the Eighth, as I'm sure you're aware, was the fattest monarch in British history.

So you think Zelner was his accomplice, and that Milverton gave him that code name because he was heavyset?

Orson Welles was heavyset. Abraham Zelner could pull small moons out of orbit.
