What if you woke up one day, got ready for work, and ran into yourself at the bend of the road? Would you hug your other self, or run? When Poe’s William Wilson finds his double tailing him at boarding school, he jabs a knife into him, only to find he has stabbed himself. When Nabokov’s Despair has a doppelganger switching identities to murder his twin and claim his own life insurance—a foolproof crime till the mind starts playing tricks. Clearly, in literature, meeting your look-alike for coffee is not the brightest idea. But there’s an entire world out there, inhabited by six others who look exactly like you—what if at least one has seen you, perhaps in the rabbithole of social media, and earns a living pretending to be you?
