Twenty nine year-old Tizzie is such an innocent. She has worked herself down to skin & bones as a dairymaid on the farm of her dear brother, Jack, his Scottish wife, Maggie, their three boys & one girl, Agnes. Expert at many things, though not in spotting conniving entrapment, Tizzie longs to see that young Agnes will not suffer her spinster fate.
In trying to help Agnes find an education & avoid a life of drudgery in their male-dominated world, Tizzie begins to suspect & then uncover Jack & Maggie’s treachery, & the family’s plots to enslave & use up Agnes too. With only her wits to guide her, Tizzie tries to right years of wrongs & set Agnes free.
