I’d been hard at work eliminating redundancies in the latest antidepressant survey when my phone started buzzing, Zoë’s name on the screen. Laptop and binders all across the kitchen table, dirty dishes piling up, half-drunk bottle of cab on the counter, even though I don’t drink, not while I’m working, not usually. But this week wasn’t usually. The disappearances had me on edge, for one thing—at first just background noise, but then I heard a name on the radio, someone I used to know in grad school, and it had started seeming very real and very wrong.
