Jean Mason has a doppelganger. She's never seen her, but others swear they have. Apparently, her identical twin hangs out in Kensington Market, where she sometimes buys churros and drags an empty shopping cart down the streets, like she's looking for something to put in it. Jean's a grown woman with a husband and two kids, as well as a thriving bookstore in downtown Toronto, and she doesn't rattle easily - not like she used to. But after two customers insist they've seen her double, Jean decides to investigate.
