Separation from her grandfather was the greatest evil she could dread; and feeling for the time as though, go where they would, they were to be hunted down, and could never be safe but in hiding, her heart failed her, and her courage drooped.

'We are quite safe now, and have nothing to fear indeed, dear grandfather,' she said.
'Nothing to fear!' returned the old man.

'Nothing to fear if they took me from thee! Nothing to fear if they parted us! Nobody is true to me.
