Sherlock Holmes and his assistant Watson have taken a case to identify the whereabouts of a mystery man. The only clue thus far is a single photograph of the man, presented here.
Watson starts in. "Well he's a stylish dresser, he's wearing a nice suit and matching canvas tennis shoes. I think that's the trend these days, yes? And we know he's definitely not married."
"Oh? Not married? I don't think I follow." Sherlock was a bit taken back by Watson's certainty on the matter, for Watson rarely seemed this certain. Sherlock wondered if, for once, he had missed some obvious clue. But quickly decided that he had not.
The question to you: Why did Watson believe this man was unmarried? And why had Sherlock not drawn the same conclusion?
