posing as a nurse, Eva administers the antidote and sneaks him past the police and the press. Later, a disguised Diabolik visits the morgue where Valmont's body has been cremated, collects the emeralds from his ashes and escapes, gifting them to Eva. Upon Ginko's realization that Diabolik is still alive, a million-dollar reward is offered for his capture; in retaliation, he blows up the tax offices. Despite pleas from the disgraced Minister of the Interior — now the Minister of Finance — the citizens refuse to pay their taxes, forcing the country into debt. Twenty tons of gold, which will be used to buy currency, are melted into a single block to make it difficult to steal; the block is loaded onto a train commandeered by Ginko. Diabolik and Eva divert the train by leaving a burning truck on the tracks and re-route it to a bridge where a bomb is placed. It explodes when the train arrives, and the gold falls into the water below. As Ginko swims ashore, Diabolik and Eva collect the gold and return to their hideout. The steel casket containing the gold is traced by the police, allowing them to track Diabolik's hideout. They close in on Diabolik, who is melting the gold into smaller ingots. As the police fire upon him, Diabolik is unable to control the smelting, and the whole cavern ends up being covered in molten gold. Diabolik is believed to have been killed, with his heat-proof suit now covered in solidified gold. The police seal off the cavern, intending to recover the gold later. As Ginko arrives to arrest her, Eva is allowed a private moment to pay her respects to Diabolik, who winks at her.
