Join Growley the chimera cat and his friend Gwen in another adventure at Grandma's house when all the grandchildren come to visit. 
There have been some thefts within the neighbourhood and Grandma and the children are nervous. They pass the time by dressing the cats in costumes, using metal detectors in the backyard and keeping up with neighbourhood alerts. Will the thief be caught? Was the garden gnome always in that position? Join Growley, Gwen, Grandma and the children in Growley and the Stolen Jewellery.
