What about Hetty?

I had just finished ADAM BEDE.It's a nice novel but one thing about which i am not satisfied is Hetty's story as there is no clear reference about her death or whatever happened to her Or may be i had missed it somewhere.Can anyone tell me?What happened to Hetty Sorrel after her hard-won release from death clutches(as she was to be hanged till death for murdering her own child)?

Reread the epilogue, it appears she died somehow just as her term of exile ended and she was preparing to return.
