Four boys and girls in a great country house, with the exciting task of trying to find a mislaid treasure, make the actors, scene and plot of this delightful mystery story. The winding stair leads from the library to a circular room so large that it can contain an exact replica of a pioneer log cabin. Henry and Ned, Lou and Carol find the winding stair a fascinating start of a mysterious adventure that lasts through a snowbound winter holiday. Boy and girl readers will share the thrill and the satisfaction of following up strange clues through the wings and vast attics of the big house and at last discovering not one, but two, lost treasures.

Mrs. Orton's mystery stories are not only extremely popular with boys and girls but are enthusiastically approved by parents, teacher and librarians because they are well written and genuine.
