The Breath She Could Not Afford

Emmerich worked on the singer's lung for two nights without sleeping. He could have patched it. A new sheet of felt, a bellows reseal, a careful retemper of the spring — three days' work, and it would wheeze its way through another year before it killed her with the soot it could no longer hold back.
