In the early 1890s, Dr. Alphonse Moreau established himself on a nameless island in the pacific, after having run out of London many years prior. His experiments with animals made him a notorious vivisectionist, forcing him to leave England. However, after being exposed by Dr. Edward Prendick, whom by accident was stranded on his island, Moreau again had to relocate, and British's intelligence set up a laboratory for the doctor in countryside England.

Intelligence tolerated Moreau's work for their own purpose; for the service, Moreau created the H-140 series, which were hybrids of bacteria that could be used as a disease weapon. During the martian invasion of 1898, a hybrid of anthrax and streptococcus, the H-142, by Moreau's creation was used to exterminate the invading alien molluscs.¹

In 1897, an albino man was murdered my a mob in Hintondean, West Sussex. It was assumed he was one Hawley Griffin - a former physicist who discovered the means to become invisible at the cost of his sanity - except that judging from his university records, Griffin was no albino. In reality, Griffin had simply captured an albino to use as a test subject, and, after hypnotising the albino to believe that he was Griffin, he turned him loose into the world, invisible and brainwashed. While the unnamed albino was slaughtered by the mob, Griffin, now invisible, hid in an Edmonton girl's school, where he impregnated at least three school girls, who believed to be impregnated by the Holy Spirit.²

This attracted the attention of British intelligence, and they dispatched Mina Murray and Allan Quatermain to the school. There they managed to subdue and capture Griffin, and afterwards intelligence managed to persuade him to work for them, in return for a pardon and a possible cure for his invisibility. He worked for them during a mission to recover the stolen substance cavorite. Griffin proved instrumental in the league's victory, tracking down the villain behind the theft - Professor James Moriarty.

Henry Jeckyll was a prominent and well-respected London doctor. He came to believe that within all humans, there existed two countering forces, good and evil, and he began to experiment to separate the two, using himself as a guinea pig. Initially, he acted out of scientific curiosity, but his experiments managed to unleash a version of him that was unfettered by society's restraints, able to enjoy all his forbidden desires; after this, Jekyll continued his work because he secretly enjoyed the freedom this alter ego had compared to his respectable life as a reputable doctor. The chemical formula he discovered not only altered his mind, but his body also changed under it's influence - he became smaller, almost ape-like, and something about his very presence caused normal humans to be repulsed by him. Jekyll dubbed his other self Mr. Hyde.

Hyde soon became notorious in London society, trampling a young girl underfoot in the street, and later being accused of the murder of Sir Danvers Carew. When Hyde's crimes necessitated Jeckyll's disappearance, he faked a suicide and fled to Paris. In the decade since then, Jeckyll's metabolism altered. He no longer needed the potion to become Hyde - any stress would do.

In 1898, Mina Murray and Allan Quatermain, along with Auguste Dupin, tracked down Hyde in Paris. He was taken to London, where Jeckyll and Hyde agreed to cooperate with British intelligence in exchange for amnesty for all Hyde's crimes.³
