Nightshade

Hugh Corbett, devoted emissary of King Edward I, is sent to Mistleham in January of 1304 in an effort to restore order after Scrope, an unscrupulous manor lord, goes back on his promise to return a priceless cross he stole from the Templars during the Crusades, and murders as heretics fourteen members of a religious order, but Corbett arrives to find the situation has deteriorated with the arrival of a mysterious bowman who is killing people at random.
