Where To Get This Card: Card Pack 1

Frankenstein is the 13th card of the 39 Clues cards.


"The novel, Frankenstein, was written between 1816 and 1817 by Mary Godwin (later Mary Shelley), when she was just nineteen years old. Mary, long suspected to be a Janus agent, was staying in Switzerland with two known Janus leaders, the famous British poets Percy Bysshe Shelley and Lord Byron. One night, the three writers challenged one another to a ghost-story contest. The one Mary produced developed into Frankenstein, one of the best-known horror stories of all time. Cahill experts from other branches have long suspected the Janus hid a Clue in the novel to commemorate Mary's accomplishment. Janus branch leaders say this story has no truth and contend the other branches are just jealous because their ghost stories aren't nearly as good."
