The Ghost of Crutchfield Hall — Mary Downing Hahn

When twelve-year-old Florence boards the crowded horse-drawn coach in London, she looks forward to a new life with her great uncle and aunt at Crutchfield Hall, an old manor house in the English countryside. Anything will be better, she thinks, than the grim London orphanage where she has lived since her parents' death.

But Florence doesn't expect the ghost of her cousin Sophia, who haunts the cavernous rooms and dimly lit hallways of Crutchfield and concocts a plan to use Florence to help her achieve her murderous goals. Will Florence be able to convince the others in the household of the imminent danger and stop Sophia before it's too late?
