As a "first guess," De Roos in his correspondence with Berghorn suggested that "A-e" might stand for ""Aftonbladets" editor," that is, Harald Sohlman. Berghorn objected that the Swedish word for "editor" is "redaktör". A few weeks later, De Roos followed up with an interview in Vampirisme.com, in which he proposed Anders Albert Andersson-Edenberg (1834-1913), a senior journalist and drama translator who cooperated with Harald Sohlman within the framework of "Publicistklubben", the Swedish Publicists' Association; he frequently used the pseunonym "A.-E." During the course of 2017, De Roos published around two dozen similarities between "Mörkrets makter" and articles Andersson-Edenberg had previously published in "Svenska Familj Journalen." In Spring 2018, De Roos summarized his findings on Andersson-Edenberg in the online magazine Vamped.org. In his 2014 essay, De Roos was the first to demonstrate the parallels between "Makt myrkranna" and Stoker's early notes. But the Dutch author also was the first to question whether "Makt myrkranna" (and thus the Swedish variants from which it turned out to be derived) actually was authored by Stoker. In this 2014 text and in his introduction to the annotated translation, he extensively discussed the chance that Ásmunddson had radically modified "Dracula", possibly even without Stoker's consent. But as the Icelandic preface showed traces of a translation from another language, these essays finally supported the idea that at least the preface had been supplied by Stoker, while Ásmundsson may have had a hand in modifying and shortening the narrative. Even after the link with "Mörkrets makter" had become evident, De Roos writes, the Icelandic prefaces continues to contain some riddles, now regarding the role of the Swedish translator/editor: How could "A-e" have learned about the Thames Torso Murders, that were hardly mentioned in the Swedish press? Why did "A-e" single Van Helsing out as a "real person," just as Stoker had done in his interview with Jane Stoddart? Why would "A-e" have used a "Hamlet" quote - a stage play Stoker knew by heart?
