Black Seraphim [EPUB ebook] 

James Scotland, a young pathologist, decides on a quiet holiday in Melchester, but amid the cathedral town’s quiet medieval atmosphere, he finds a hornet’s nest of church politics, town and country rivalries, and murder. He is called upon to investigate and finds that some very curious alliances between the church, state and business exist. With modern forensic pathology he unravels the unvarnished truth about Melchester, but not before a spot of unexpected romance intervenes.
