Secret staircase. Webb H.

Polly and her friend Rex is a difficult girl and a dog. More precisely, Polly is a completely ordinary girl, and Rex is the guardian of the old Penhallow mansion. And this whole huge mansion is full of dogs: they stick out muzzles from bas -reliefs and balusters, look from paintings, sit with statues and figurines. All of them once lived here in Penhallow, and forever remained his guardians. And one such magic dog is so sad that even Polly felt it. Once upon a time, a little girl forgot the toy in the room, but the dog did not forget her mistress. Polly and Rex do not know what to do, how to get a dog out of his sadness. Is it possible to find a girl who is just as sad and which the dog could help?
