Trapped in the catacombs beneath the River Thames, aided only by the psychopathic Hawley Griffen and the snarling storm of rage and hatred known as Edward Hyde, Miss Murray and the legendary Allan Quatermain endeavor to retrieve the wonder- metal Cavorite from the remorseless devil-doctor who rules Limehouse. Meanwhile, in the shadow-kingdom of the League's Victorian spymasters, the identity of the mysterious Mr. M is finally and shockingly revealed.
