Tan Callahan, Great Detective, is back in a series that has been described as 'interesting, exciting and excellent!' Tan has never been fond of the old machinery shed. It's dusty and airless, full of dark secrets and bad memories. There's a mountain of junk in there too, broken chairs, sideboards, couches, books and overcoats. But worse still is the creepy portrait of an unnamed little girl. She has cold, dark eyes and a gloomy face. And if the girl isn't scary enough the china doll she's holding looks downright malicious. Tan vows to avoid the shed and the portrait at all costs. But when Great Aunt Aggie comes to stay, Tan discovers there's a whole lot more to the portrait than she ever imagined. There's a whole lot more to Great Aunt Aggie, too.
