As he started toward his room Tom Swift heard the voice of the housekeeper calling to him:

"Tom! Oh, Tom! Come here, quickly!"

"What's the matter?" he asked, in vague alarm.

"Something has happened to your father!" was the startling reply. "He's fallen down, and is unconscious! Come quickly! Send for the doctor!"

Tom fairly ran toward his father's room.

"How did it happen? When was it?" he asked of Mrs. Baggert, as he held up his father's head, and noted that the aged man was breathing slightly.
