Ottoline Brown lives in the Pepperpot Building in the Big City with her friend, a small, very shaggy creature rescued from a Norwegian bog called Mr Munroe. Her parents are away, travelling and gathering objects to include in the family collections (which include Odd Shoes, Parrot Clocks, Portable Fishbowls and Emperors' Hats). Ottoline looks after the collections while being looked after by a host of service companies like The Home Cooked Meal Co. and Smith & Smith Pillow Plumping and Curtain Drawing Technicians. She is a very clever and inquisitive girl, with a diploma from the Who-R-U Academy of Disguise and is very interested in what's going on around her: from neighbour' conversations she listens to via the heating pipes in the laundry basement to less commonplace mysteries - and it's her who solves the mysterious series of high-society crimes baffling the police: lapdog disappearances followed by daring burglaries.
