- A grizzly bear walked all the way from the zoo to my front door and not a single person noticed him. I suppose it helped that it was night, and that he was wearing a big black duffle coat with an enormous hood that covered his hairy head. He knocked on the front door three times, loud knocks that shook the house. Patrick makes his unexpected guest at home, while keeping him hidden from the neighbours, police and his very distractable mum! An intriguing, engaging and rather remarkable tale.
