Biography
When the Master died, Laura encountered the Fifth Doctor and his friends Tegan Jovanka and Turlough. She was drawn into the world of the Time Lords when many patients in the nursing home fell into a deep coma. Laura teamed up with Tegan to investigate and later discovered the Master was neither dead nor the man she thought he was. After discovering he was behind the deaths of the nursing home residents, she helped the Doctor defeat him.

She later discovered the nursing home wasn't real and was designed to trap people. A devastated Laura then worked to help the Doctor defeat the Master, freeing her from his powers. (PROSE: The Velvet Dark)
