The National Gallery is the art museum on Trafalgar Square. In Triple Theft, Jacob and Maxwell Roth visit it while kidnapping Starrick's associates.
It began with John Julius Angerstein's collection shown in his house on Pall Mall. William Wilkins designed the new building, placed between the rich West End and the poorer East End.
Roth wants Starrick's art dealer, Hattie Cadwallader, because her sales fund his businesses. Jacob asks children around the gallery, learns she stole a statue nearby, finds its empty pedestal, and is told she hides in the sewers. He grabs her there and carries her back to Roth's carriage. The same run then takes in Benjamin Raffles at St James' Park and Chester Swinebourne at Scotland Yard.
Scotland Yard
Scotland Yard is the Metropolitan Police headquarters in the Strand. Several Jack the Ripper memories involving Inspector Abberline reference it.
St James' Park
St James' Park is London's oldest royal park, just east of Buckingham Palace in Westminster. In Triple Theft it is where Jacob and Roth go after Starrick's head of security, Benjamin Raffles.
