Mr Sherlock Holmes was measuring the white spots dotting the body of the dark-haired, middle-aged man seated before us. The Royal Medical Society had asked Holmes to diagnose this puzzling skin malady. Holmes announced, “Watson, this is most interesting. All the lesions measure exactly ¾ inch square, roughly the size of a large bean. Each spot has 2 white hairs within it. ”

I wasn't sure where Holmes was going with this. To me, the diagnosis was vitiligo of 7 days' duration. I glanced at Holmes. Despite the passage of time, Holmes was still sharp of mind and could solve any crime or challenge placed before him.
