The Book of Renfield: A Gospel of Dracula is a 2005 novel written by Tim Lucas.

[citation needed] The Book of Renfield works mainly as a companion piece to Stoker's original novel.

In some cases, excerpts from the actual book are used but are modified and expanded under the pretense that Dracula is nonfiction and that Seward's entries were "edited, and in some instances, rewritten by John L. Seward before he provided them for the use of Mr. Bram Stoker, at the request of Mr. and Mrs. Jonathan Harker".

The book starts with a man discovered outside the ruins of Carfax Abbey, feasting on a rat, whose only form of identification is a handkerchief that reads "R. M. Renfield".

He is taken in to Seward's asylum, where his sessions with the doctor reveal fragments of his tragic past and how he came to be Count Dracula's pawn.
