For women of Penny's generation, being on hand for elderly parents is just part of life.
But for Penny, things have become a little more serious...
When she receives a frantic phone call from her parents one night, with express instructions NOT to call the police, Penny rushes over at once. But they haven't had a fall.
They haven't forgotten their computer passwords. They've killed someone. And his body is lying in the garden, right next to the rose bushes.
