The wallet was not special; the old leather had been crumpled at the edges, and the card slots were as torn as a cat’s blanket. Inside, the contents appeared basic at first glance. A few bank notes, some dirty coins, an array of loyalty cards, and a debit card belonging…to me.

I read and reread the card, until, in a fit of sense, I realised the possibility that another person may share my name.

So I continued to peruse the wallet, searching until I found a driver’s license. My name again, sitting proudly beside a picture of me. This time I let out an audible gasp. It was, without a doubt, me. I checked the birthday too, but apparently my döppelganger was born on the same day as me. Even the height and weight were correct.

By this stage I could feel myself shaking, conscious of everything and everyone around me. When I finally built up the courage to re-enter the stream of innocent-looking people, I found no unknown twin brothers. The stream went on, and I was glad to be a part of it.

As I broke from the flow to enter my apartment complex, I saw him in the glass reflection; a darkly dressed man with an unbreaking stare on me, assuring himself with the glock in his hand.
