“James Heron stepped from the personal transport as Herbert, the family’s outmoded android butler, opened the front door of Scrabo Farm. There were infinitely more efficient and newer model android servants available, but neither James Heron nor his sister Niamh L’Estrange would dream of scrapping the mechanical attendant that had served the family so well, and enlivened their childhood with its fussy care of them both.
“Hello, Herbert, is my sister home?”
Answering in the slightly mechanical voice that James had liked so much when he was a boy, Herbert said, “She is in her study, Captain. I have alerted her to your arrival.”
