There's Leslie, so clever and beautiful you'd think she was meant for a queen, and instead she's cooped up over there, robbed of almost everything a woman'd value, with no prospect except waiting on Dick Moore all her life.

Though, mind you, Mistress Blythe, I daresay she'd choose her life now, such as it is, rather than the life she lived with Dick before he went away.
