The League travels to the London Docklands to recruit Dorian Gray, Mina's former lover who is immortal due to a missed cursed portrait. The Fantom's assassins attack but the League, aided by U.S. Secret Service Agent Tom Sawyer, fends them off. Gray and Sawyer join the League. They then capture Edward Hyde in Paris, who transforms back into his alter ego, Dr. Henry Jekyll, and joins the League after being offered amnesty. The League travels to Venice in Nemo's submarine, the "Nautilus", but they soon deduce there may be a mole on board when a camera's flash powder residue is found in the wheelhouse and one of Jekyll's transformation formulas disappears. Suspicion falls on the missing Skinner.
