Prompt #11: Behind
People wonder how those two can live together without murdering each other; half of us believe they're partly mad, and the other half that they're completely so.
It's common knowledge that Mr. Holmes despises waiting for someone to catch up to him mentally or physically; but somehow he doesn't mind either, when it's the Doctor. And that puzzles the force more than any unsolved murder case.
But I know the answer: the Doctor may always be one step behind Mr. Holmes, but that one step is still a half-dozen closer than the rest of us can or will ever get.
