In The Expats, Kate Moore traipses across Europe, chasing her own tail. In real life, I too traipsed across Western Europe. Fact and fiction intersect on this interactive map, where Kate Moore and Chris Pavone both traveled with their families . . .

Stay: Durley House, Sloane Street (preferably in a suite), a few blocks from Wilton Crescent, home of the book’s superrich villain.
Eat: Tom’s Kitchen, Cale Street, Chelsea, with the children. Or St. John Hotel, near Leicester Square, without.
Do: The Science Museum and the Natural History, in Knightsbridge. The super-toy-store Hamleys, in Regent Street. The Portobello Road flea market, in Notting Hill.
Stay: The Toren, on Keizersgracht.
Eat: De Reiger, on Nieuwe Leliestraat.
Do: For the children, the great science museum, in the harbor. For the grownups, great boutique shopping on De Negen Straatjes—“the Nine Streets”—in the Canal District.
Eat: Borchardt, on Französische Strasse, but only if you can manage to wear proper shoes. This is a place where presidents dine.
Do: The Holocaust Museum under the memorial, or just the street-level memorial if you don’t want to explain the whole shebang to children. This is where Kate meets up with her contact.
Eat: The Brasserie d’Ile-St-Louis, on the Ile, is where Kate reunites with her family. The grownups dine at Chateaubriand, in the 11th arrondisement, then go dancing at Le Baron, near the river in the 16th. After the children’s school interview, they all have a snack at the Flore, on the boulevard St-Germain. The final scenes in the book take place at the Le Comptoir du Relais St-Germain, on the Carrefour de l’Odeon. Stay: Hotel Parc Beaux-Arts, around the corner from rue de l’Eau (where the fictional Bill and Julia live, and where the real-life Chris Pavone and family lived).
Eat: Kate has a confrontational meeting with Bill and Julia at Chiggeri, in the Haute Ville. She has a Michelin-starred but tense dinner with her husband at Léa Linster, 20 minutes out of town, in Frisange. But for the best meal in the city, totally nonfiction, go to Mosconi, in Grund (across the river from Amazon’s offices).
Drink: Have a coffee at Coffee Lounge on rue de la Poste, which is where a good portion of The Expats was written.
Eat: In downtown Bamberg, have a snack at Café Muller. In Munich, dine at Spatenhaus an der Oper, on Residenzstraße near the Opera, or Osterwaldgarten, up in Schwabing near the Englischer Garten.
Do: Follow the Moores’ trail to the obscenely picturesque town of Rothenburg-ob-der-Tauber, and Mad King Ludwig’s castle Neuschwanstein (the physical model for Disney’s castle), and the UNESCO World Heritage city of Bamberg. In Munich, go to the Alte Pinakothek, which is where Kate meets up with Hayden and a grand tour of Old Masters.
Eat: In Geneva, have a café, as Kate does, anywhere on the Place du Bourg de Four, at the top of the hill. Eat at Armures, a few blocks away on the rue Puits-St-Pierre.
Do: Ski for a week in a self-catering apartment at Avoriaz, a pedestrian-only purpose-built resort at the top of a mountain, in the middle of an immense web of interconnected resorts called Les Portes du Soleil.
