Please write a story about a man named NAME_1 who comes to England from New Jersey to track down the Highgate vampire. He has never left the U.S. before but some research he has done convinces him that something sinister really does haunt Highgate Cemetery. He confides in his English friend, actor-musician NAME_2, who isn't convinced. NAME_1 rents a studio flat in Highgate with a view of the cemetery. He does not have any experience in dealing with occult matters but he is smart and decides to search for his quarry with technology. He can launch drones at night from his balcony and has an advanced military-grade targeting pod camera mounted on the balcony that can monitor part of the cemetery optically and with infrared. NAME_1 needs to find evidence of the vampire at minimum (to gain allies) and destroy it at best, all the while protecting himself and his friend NAME_3 (who he has a secret crush on) from vampires or occult forces. NAME_1 doesn't know if any mortals or other entities protect or work with the vampire. He also has to avoid getting arrested by authorities who wouldn't believe him or being declared insane by anyone else who might learn what he's up to. At times he feels like he's in over his head and wishes he could get his friend NAME_3 to help him, which would let him keep him close and safe and to have NAME_3's knowledge of England, his contacts and his resources available.
