       Her memory was gone.

      It came to Katharine like a soft shock, like a blow inside the head. She was in the yellow bedroom at her daughter's house in Maine, standing at the bureau, getting ready for lunch. She'd just finished doing her hair, smoothing it back to her modest bun, tucking in the small combs to hold it in place.

The place where her memory had been was gone, blurrily erased, like a window grayed by mist. Beyond it
