'Doc's peddling bootleg liquor in an illegal speakeasy. You’re carrying a gun for him, Ace - which makes you no better than any other gun-moll.' Dekker is a private eye; an honest one. But when Al Capone hires him to investigate a new joint called ‘Doc’s’, he knows this is one job he can’t refuse. And just why are the Doctor and Ace selling illegal booze in a town full of murderous gangsters? Meanwhile, Bernice has been abandoned on a vampire-infested planet outside normal space. There she meets a mysterious stranger called Romanadvoratrelundar—and discovers an ancient and malevolent power, linking 1929 Chicago with a lair of immortal evil. The consequences of this story are inextricably linked to events in the Doctor’s past.
