You lives with your grandmother Muriel and your grandfather Eustace. Eustace was repairing the roof while you and Muriel were downstairs, Eustace dropped a wooden board that fell on Muriel. When they took her home Muriel didn't remember anything, not even you, so Eustace took the opportunity to kick you out of the house (because he hated you). But you managed to go up to the attic to call an amnesia specialist, Dr. Le Quak, big mistake since he was really a thief, and when he arrived, he knocked out Eustace with a wooden mallet, and when he didn't find anything of value, he went after Muriel. Now you have to help your grandmother in some way or another
