The dead duke, his secret wife, and the missing corpse

"At the close of the Victorian era, as now, privacy was power. The extraordinarily wealthy 5th Duke of Portland had a mania for it, hiding in his horsedrawn carriage and creating tunnels between buildings to avoid being seen. So when, in 1897, an elderly widow asked the court to exhume the grave of her late father-in-law, T.C. Druce, under the suspicion that he'd led a double life as the 5th Duke, no one could dismiss her claim. The eccentric duke, Anna Maria was sure, had faked his death as Druce, and, therefore, her son should inherit the Portland millions. A lurid, decade-long case was born."--Provided by publisher.
