A charming story about the importance of gardens, of grandparents and of families doing things together.

When our dads say, 'Money doesn’t grow on trees you know,' Grandma smiles and says, 'Mmm, but knickers do.'

WHAT?! Grandma’s got an underpants tree? She sure has and you know what else? It blooms all year round with all kinds of knickers to suit everyone in the family.

But one morning, Grandma finds her precious tree has been attacked, with knickers strewn all over the garden. Grandpa and the grandkids spring into action, setting up an after dark stakeout.

Will the kids be able to stay awake long enough to find out whodunnit?
