As soon as she moves to Penhallow Place, Polly can't wait to unravel its mysteries. One night, she sleepwalks outside and wakes to find her hand on the stone statue of a dog. The dog introduces himself as Rex, an Irish Wolfhound, who lived at Penhallow many hundreds of years earlier. And he is not the only resident ghost...
Polly and Rex find a new dog to wake - a toy dog that belonged to two evacuee children. But to their surprise it seems this dog doesn't want to be woken!
