A doppelgänger is a look-alike or double of a living person, sometimes portrayed as a paranormal phenomenon, and is usually seen as a harbinger of bad luck. In other traditions and stories, they recognize one’s ‘double-goer’ as an evil twin. Doppelgänger is a German word. In modern times, the term twin stranger is occasionally used.
The word “doppelgänger” is often used in a more general sense to describe any person who physically or behaviorally resembles another person.
I once knew somebody who claimed to have met his doppelgänger by chance in a pub. I asked him how he felt about it and he said that it was exciting, it fact he had been beside himself all evening!
Caxton has a doppelgänger and it arrived in Windsor a few hours after we did. “Eclipse No.2” is a Hudson boat by the look of it and although the shells are different, the paint schemes are so similar it’s uncanny.
