'Can you come round?' Dad says tremulously.

'Of course. Are you OK? Is it Mum?'

'No!' He almost shouts it. 'Just come quickly. The garden...the...body... we need you, Penny.'

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.

Everyone is capable of murder. They just need to meet the right person.
