H.H. Holmes is the America’s first notorious serial killer, but do you know him as England’s most prolific killer? American Ripper follows the grandson of H.H. Holmes as he presents the evidence he’s gathered that seems to indicate that H.H. Holmes wasn’t only the Devil In The White City, but also Jack The Ripper. I’m already suspicious, I love this type of topic and this one is the most widely discussed mystery of all times. Check out the first trailer below and check out the series on History in April.
