Cornell Dyer and the Calcium Deficient Bones

When supernatural super sleuth Cornell Dyer finds himself between sleuthing jobs, he fills the
time by teaching science while the real teacher is ill. But in a school that’s supposedly getting
remodeled, Cornell encounters one mystery after another: vanishing classroom skeletons, plants
that come and go, and a piano for every student. Cornell is certain his classroom holds the
answer - and that he is one of the clues.
