Cosmo the witch-cat is delighted that evil Sybil - the most terrible of witches - is safely in prison. In fact, she's even been fitted with a special tag, which means that if she tries to escape she will be turned into a frog. But then mysterious goings-on are reported on Witch News.
Baby witches are being visited by strange midwives and having their toenails clipped and stolen. Cosmo is sure something sinister is afoot. Could a highly wily witch be brewing a spectacularly spooky spell?
