Yay! I love this series. It's one of the best things in comics and definitely one of the best, if not the best, Dark Horse title. You can start on any series too which is always nice. From Dark Horse Comics:
Dark Horse is proud to announce the newest installment in the Resident Alien universe, Resident Alien: The Man with No Name. Peter Hogan (2000 AD, Tom Strong) and Steve Parkhouse (Milkman Murders, Doctor Who) will revisit Dr. Harry Vanderspeigle and his mysterious adventures in Patience, Washington.
Resident Alien chronicles the life of Harry, an alien who crash-landed on Earth and is forced to hide in plain sight among humans. While awaiting rescue and dodging government agencies intent on capturing him, Harry spends his time solving murders and other mysteries in a small Washington town. In The Man with No Name, Harry investigates a huge, bizarre fire attributed to a possible drug ring, while fending off the investigative prowess of the United States government.
Resident Alien writer Peter Hogan explained the creative premise behind The Man with No Name: “In this series Harry’s not only dealing with a murder mystery; he’s having to deal with dramatic developments in his personal life as well — and readers will finally learn the answers to some of their questions about Harry’s past.”
Dark Horse, Hogan, and Parkhouse published the first Resident Alien series in 2012. The Man with No Nameis the fourth Resident Alien miniseries; it was preceded by Welcome to Earth!, The Suicide Blonde, and The Sam Hain Mystery. The first issue of The Man with No Name goes on sale September 14, 2016, with the next three issues of the miniseries published monthly.
