No one else was in the room.

The people who had been disturbing her by doing things had gone away.
"Now," she whispered dragging out word after word, "no one will--ever--ever know." But she was not conscious she had said it even in a whisper which could be heard.

She thought the thing had only passed again through her mind.
"Donal! Blown--to--atoms," she said in the same way.

"How small is--an atom ?" She was sinking into the blackness again when the man dropped her wrist quickly and did something to her which brought her back.
"Don't!" she moaned.

"Please--don't." But he would not let her go.
* * * * * Perhaps days and nights passed--or perhaps only one day and night before she found herself still lying in her bed but feeling somehow more awake when she opened her eyes and found the same man sitting close to her holding her wrist again.
"I am Dr.Redcliff," he said in a quiet voice.
