Herbert Peabody is a farmer who grows fruit and vegetables in his big, big vegetable patch at Mulberry Tree Farm.

When he discovers that his new neighbour, Bee, is having trouble finding enough pollen to supply her family's hive, Herbie decides to lend a hand to find more flowers.

But there's another concern: The Voice That Belongs to Nobody has taken up residence in the once-grand mansion of Huffelton, scaring away anyone who ventures inside the neglected, lonely grounds.

Will Herbie be able to find more flowers in tome for Bee's hive? And can he solve the mystery behind the voice in Huffelton House?
