The title refers to the penny dreadfuls, a type of 19th-century British fiction publication with lurid and sensational subject matter. The series draws upon many public domain characters from 19th-century British and Irish fiction, including Dorian Gray from Oscar Wilde's The Picture of Dorian Gray; Mina Harker, Abraham Van Helsing, Dr. Seward, Renfield, and Count Dracula from Bram Stoker's Dracula; Victor Frankenstein and his monster from Mary Shelley's Frankenstein; and Dr. Henry Jekyll from Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde.
