The Orient Express did not run for a single day of Mata Hari's career as an accused spy. The Compagnie Internationale des Wagons-Lits suspended the service in July 1914, and the first post-war departure did not leave Paris until February 1919 — sixteen months after Margaretha Geertruida Zelle was shot in the moat at Vincennes on 15 October 1917.
The image of her crossing wartime Europe in a varnished sleeping compartment, ciphers sewn into the lining of a coat, is therefore chronologically impossible. What the archives hold instead is stranger and rather sadder: a divorced Dutch dancer moving around the war by neutral steamer, and a French military tribunal that did not need to prove she had passed anything at all.
The service was suspended for the whole of her war
Nagelmackers had been running international sleeping cars since 1876, and his Express d'Orient first left the Gare de l'Est in 1883, twice weekly via Strasbourg, Munich, Vienna and Budapest; a direct Paris–Constantinople working followed in 1889. It rested on an assumption that collapsed in the summer of 1914 — that one company's carriages could cross half a dozen frontiers by agreement. Once the frontiers became front lines the through service stopped, suspended from July 1914, and the first post-war Orient Express did not depart until February 1919, routed through Switzerland to avoid German soil.
The southern variant, the Simplon Orient Express, began on 11 April 1919 from the Gare de Lyon via Lausanne, Milan, Venice and Trieste, reaching Istanbul from 1920. That is the train most people actually picture, and it did not exist in Mata Hari's lifetime. The story of Nagelmackers and the European sleeping car is inseparable from the story of open borders, which is exactly what her war lacked.
Neutral steamers, not sleeping cars
Her Dutch passport was her one real asset, and the documented itineraries show her using it the long way round. In June 1916 she left Amsterdam aboard the Dutch steamer Zeelandia, disembarked at Vigo in Spain, was searched and questioned at the Franco-Spanish frontier at Hendaye on 13 June, and reached Paris three days later. That October she took an express south to Spain again, and in November boarded the Hollandia for the Netherlands. The ship called at Falmouth for a wartime inspection, and she was taken to London for questioning by Sir Basil Thomson of Scotland Yard.
Accounts differ on the detail of these interceptions. The British government's own account, drawing on the MI5 files at The National Archives, places a first detention in December 1915 and a spring 1916 incident in which she was held on a mistaken identification as the German agent Clara Benedix; other narratives fold both into the November 1916 stop. All agree on the mode of transport: she went around Europe by sea because she could no longer go through it by rail.
The one luxury sleeper that did cross wartime Europe
There was a grand through train running while the Orient Express sat idle, and it was German. The Balkanzug began on 1 January 1916 as a twice-weekly sleeping-car service from Berlin to Constantinople by way of Dresden, Vienna, Belgrade and Sofia, covering roughly 1,900 kilometres in about 58 hours. Assembled partly from Wagons-Lits vehicles taken over by the Central Powers, it existed as much for propaganda as for passengers: proof that Berlin could reach the Bosphorus without Paris. Mitropa, which held the monopoly on cross-border sleepers from 1 January 1917, took the service over; it was discontinued in October 1918.
It is the closest thing to the legend's setting, and Mata Hari never went near it. Her wartime geography was The Hague, Madrid, Paris and the Atlantic sea lanes — not the Balkan corridor that today's Danube Express loosely retraces.
What the dossier actually contains
The substance of the case was thin. Captain Georges Ladoux of French intelligence put her under surveillance and turned up nothing; the Deuxième Bureau engaged her in 1916, and she once named a figure of a million francs for her services. She had earlier taken 20,000 francs from a German diplomat, money she maintained was owed to her rather than paid for intelligence, and German records called her H-21. The decisive material was a set of telegrams sent from Madrid to Berlin in January 1917 by the German military attaché, Major Arnold Kalle, which the French read.
The Fries Museum in Leeuwarden, which holds her scrapbooks and related military papers, puts the legal position bluntly: the investigating officer, Captain Pierre Bouchardon, could not prove she had supplied the Germans with damaging information, and did not regard that as an obstacle. Under wartime military law, contact with the enemy was sufficient. She was tried on 24 July 1917, convicted, and shot twelve weeks later at the age of 41. The MI5 assessment released a century later describes an ineffective amateur rather than a master agent, and the French dossier — some 1,275 pages — was declassified in 2017. Her historians, among them Pat Shipman, Julie Wheelwright and Russell Warren Howe, agree that no specific defeat or leak was ever traced to her. They disagree over whether the code number and the cash mark a genuine if useless recruitment, or a woman improvising for money in front of two services that both found her expendable.

Where the sleeping-car legend came from
The confusion is not baseless, merely misdated. Before 1914 she did live on the international expresses, because that is how a touring performer moved: Paris, then Madrid and Monte Carlo in 1905 and 1906, then Berlin, Vienna and Milan. Her scrapbooks, now in Leeuwarden, run from 1905 to 1915 and stop where her career does. Her last performance was in March 1915.
The rest was assembled afterwards, largely in Hollywood. Her albums were meant to be destroyed on her instructions; instead a servant sent them to California in the 1930s as film research, and they spent the Second World War in a bank vault. Greta Garbo's Mata Hari arrived in 1931, Graham Greene's Stamboul Train in 1932, and Agatha Christie's Murder on the Orient Express in 1934 — set, precisely, on the Simplon service that began two years after she died. Two separate pieces of interwar mythology, the glamorous female spy and the sleeping car full of secrets, were welded together by writers with no particular reason to check a timetable.
The trains that carry the story now
The carriages a traveller can board today are, appropriately, the ones she never saw. James Sherwood began buying Wagons-Lits stock in 1977 with two vehicles at a Monte Carlo auction, and eventually spent some US$16 million on 35 sleeping, restaurant and Pullman cars, most built in the 1920s and 1930s. Dining car 4141 carries René Lalique glass panels; the first London–Venice service ran on 25 May 1982. The Venice Simplon-Orient-Express follows the Simplon route rather than the original; our guide to how the Orient Express trains compare sets out which name belongs to which history. For the Italian end of the same lineage there is Orient Express La Dolce Vita, while the wider heritage fleet reaches the Central European corridors the wartime detours avoided.
What none of them offers is Mata Hari's actual journey: a Dutch steamer, a frontier search at Hendaye, a cell at Saint-Lazare. The sleeping car is the better story. The record is the more interesting one.
