Winter break is off to an exciting start with Oz and D. B. jetting off to London for Oz¹s mom¹s opera premiere. And Glory Goldenleaf, private eye, comes along for a pleasure trip.

And when the Crown Jewels are stolen, Oz, D. B., and Glory are in store for a James-Bond-meets-Scotland-Yard kind of mission the likes of which the spy world has never seen!
