Polly is Rose's oldest friend. So when she calls with the news that her husband has died, Rose doesn't think twice about inviting her to stay. She'd do anything for Polly; it's always been that way. Polly has never been one to conform - it's one of the qualities that Rose most admires in her - and from the moment she and her two boys arrive on Rose's doorstep, it's obvious she's not the typical grieving widow. But the longer Polly stays, the more Rose wonders how well she really knows her.
