"It must be from that polio," she told Essie, knowing all the time that she was almost well now and needed plenty of rest and careful doses of exercise. "It makes my eyes—funny."

Essie smiled back glassily and Ruth laughed. It was good to awaken and see the thick black arms of the maple tree outside the windows. It was good to have the cool green leaves waving at her, and see the filtered dapplings of sunshine cross and recross them.

She loved that old tree. She had played among its long horizontal branches from childhood. Her brother, Alex, who had been killed in the Normandy Landing during World War Three, had loved the tree too. He had built the railed, shingled-roofed little nest high up in the tree's crotched heart where Ruth kept some of her extra-special notes and jewelry and a book of poems.

One of the two paintings on the bedroom walls was of the old tree. The tree dominated the old story-and-a-half white house with the green shutters that was the Halseys' home. Her home. Alex had painted that picture as well as the other showing the graceful loop of the river and the roofs of the village of Thayer in the distance. Ruth had been with him as he painted that second picture from the jutting rock ledge five hundred feet above the river.

"I was just ten then, Essie," she chirped gaily. "I remember how afraid I was of the height and how Alex scolded."

But Alex was dead now and all she had to remember of him was the paintings and the photographs that Mother kept in a battered brown leather folder. For a moment the bright sunlight in her beloved maple tree's leaves seemed to dim and the room wavered about her. She wondered about that. She must tell her father or her mother.

Perhaps the polio, light touch of it or not, had hurt her eyesight. Glasses! She shuddered at the thought.

The room shimmered and blurred—and suddenly broke apart to reform into something.... She squinched her eyes shut to the hideous vision. And then opened them the merest slit.

Nothing had changed....

"MOTHER!" she cried. "Daddy!" she cried. "What has happened?"
