Cranarch

Lord Cranarch once held a high position in British intelligence. He lived at the family home of Repton Abbey, where he often entertained guests at dinner, including the Doctor. On one such occasion his household was invaded by aliens led by Lord Ryzt. Their memories were drained to further an invasion of the country. The invasion was thwarted when the Doctor used the alien technology to hypnotise them into thinking the planet wasn’t worth the effort and they should go home. With the aliens gone, the Doctor and his companions stayed for dinner. (DWA: The Demons of Repton Abbey)
