The London Map I'm using for The Getaway is Berndtson & Berndson's "London City Center Map". On this map, Jolson's house is on Upper Brook St. on map grid F6. The Serpentine gallery, hosting the China art exhibit in the game, is on map grid H3. The Snow Hill Police station is at E13. I'll post other locations as I find them. If you can't find this map, the back section of Eyewitness Travel Guide London also has detailed maps, but they are spread over many pages. On these maps, Serpentine Gallery: 11-A4, Jolson's house: 12-D2, Snowhill Police Station: 14-F1.
