Actress Olivia Colman claims to be 'the least adventurous person I know.'

Olivia finds records that reveal Harriot was an orphan in 1811 on a ship bound for England from (then) Calcutta. Harriot's father was an Englishman, but the identity of her mother, who gave birth to her in a remote Indian village, is a mystery Olivia delights in solving.
