The Book with the Orange Leaves

What kind of book would be printed on orange leaves? It could only be the one book that contains all of the wisdom of the ancient Chinese, as told in hundreds of aphorisms The Way Out. Featured in a half dozen webwork mysteries by Harry Stephen Keeler, The Way Out is the only thing keeping one-handed Stefan Czeszcziczki's wife alive as she awaits an operation. How "Zicky" uses its wisdom to save her life is a tale only America's most forgotten author could have written.
