Deadly Sweet Cupboard [EPUB ebook] 

One wet, windy, winter’s morning Harey decides to have a party because it is his birthday. Having been given some pot-pourri as a present he tries to drink the essential oil but Scampi saves him just in time, knocks over a candle and causes a fire, goes to use some plastic washing pouches for eating as jellies and swallows some "sweets" he finds in the medicine cabinet in the bathroom.
