The Lord Beneath the Lupins

Digging up trouble is becoming a habit for Diana Flowers. But when she finds a collection of bones buried where she had planned to plant out her lupins, she can't believe her bad luck . . . especially as she doesn't think Diggory the dog is the one who buried them. Fergus has a wild theory about the identity of the skeleton beneath the flower field. More shockingly still, he might just be right. Diana and Fergus are soon in the middle of another mystery, as they unravel the largest conspiracy they've ever faced and search for the truth about the lord beneath the lupins.
