I'm looking for a book I read years ago about a little old lady (I'm sure it was a D King Smith but could be wrong)!
She ran away from her nursing home as she was bored and boarded a train to 'anywhere'. She ends up on a beach and meets a group of siblings (their surname was 'Good'). She moves into a granny flat attached to their parents house and adopts a stray dog from the beach. Also sure the parents were dentists?
Very vague but hoping someone can help!!
