Jack and Max think a ghost has taken their kitten. Of course, Detective Dog knows there is no such thing as a ghost, but he must go look in a creepy old house. And that's when his rib-tickling problems begin!
I do not like this book because it says over and over there are no such things as ghosts. That's how you close off a child's 6th sense. I'm, personally, not a fan of that.
