London, 1905. 

Eight years after the events as dramatized in Bram Stoker's novel DRACULA, the King Vampire Dracula is dead, and Jonathan and Mina Harker, married soon after, are respectively a successful lawyer and a successful school teacher. The Harker's also have an eight year-old son called Quincy, named after their fallen comrade Quincy Morris of Texas, who died trying to kill Count Dracula. 

At night, the Harker's continue to pursue another vocation. One that is now partly an obsession after their life-changing experiences chasing and killing the Lord of the Undead...they are vampire hunters. 

In HARKER AND THE SHADOW OF DRACULA, the Harker's balance daily life in the early 20th century with their busy schedules, each balancing a very full day with their dual professions. As the eighth-year anniversary of the vanquishing of Count Dracula approaches, young Quincy Harker, their only child, falls victim to a horrible malady that doctors cannot find an answer or cure for. 

Convinced that their son is bewitched or even possessed by a gypsy sorceress in retribution for killing Dracula, Jonathan and Mina must return to Castle Dracula in Transylvania, battling the forces of darkness sworn to protect and uphold the legacy of Count Dracula, and try and save their innocent son. 

 

- From the novel DRACULA by Bram Stoker

"Seven years ago we all went through the flames. And the happiness of some of us since then is, we think, well worth the pain we endured. It is an added joy to Mina and to me that our boy's birthday is the same day as that on which Quincey Morris died. His mother holds, I know, the secret belief that some of our brave friend's spirit has passed into him. His bundle of names links all our little band of men together. But we call him Quincey.
In the summer of this year we made a journey to Transylvania, and went over the old ground which was, and is, to us so full of vivid and terrible memories. It was almost impossible to believe that the things which we had seen with our own eyes and heard with our own ears were living truths. Every trace of all that had been was blotted out. The castle stood as before, reared high above a waste of desolation.
When we got home we were talking of the old time, which we could all look back on without despair, for Godalming and Seward are both happily married. I took the papers from the safe where they had been ever since our return so long ago. We were struck with the fact, that in all the mass of material of which the record is composed, there is hardly one authentic document. Nothing but a mass of typewriting, except the later notebooks of Mina and Seward and myself, and Van Helsing's memorandum. We could hardly ask any one, even did we wish to, to accept these as proofs of so wild a story. Van Helsing summed it all up as he said, with our boy on his knee.
We want no proofs. We ask none to believe us! This boy will some day know what a brave and gallant woman his mother is. Already he knows her sweetness and loving care. Later on he will understand how some men so loved her, that they did dare much for her sake.
