Inayat Khan was betrayed to the Germans, either by Henri Déricourt or Renée Garry.
Déricourt (codename Gilbert) was an SOE officer and former French Air Force pilot who had been suspected of working as a double agent for the Sicherheitsdienst.
Garry was the sister of Émile Henri Garry, the head agent of the 'Cinema' and 'Phono' circuits, and Inayat Khan's organiser in the Cinema network (later renamed Phono).
Émile Henri Garry was later arrested and executed at Buchenwald in September 1944.

Renée Garry was allegedly paid 100,000 francs (some sources state 500 pounds).
Her actions have been attributed at least partially to Garry's suspicion that she had lost the affections of SOE agent France Antelme to Inayat Khan.
After the war, she was tried, but escaped conviction by one vote.

On or around 13 October 1943, Khan was arrested and interrogated at the SD Headquarters at 84 Avenue Foch in Paris.
During that time, she attempted escape twice.
Hans Kieffer, the former head of the SD in Paris, testified after the war that she did not give the Gestapo a single piece of information, but lied consistently.

However, other sources indicate that she chatted amiably with an out-of-uniform Alsatian interrogator, and provided personal details that enabled the SD to answer random checks in the form of questions about her childhood and family.

Khan did not talk about her activities under interrogation but the SD found her notebooks.
Contrary to security regulations, she had copied out all the messages she had sent as an SOE operative (this may have been due to her misunderstanding what a reference to filing meant in her orders, and also the truncated nature of her security course due to the need to insert her into France as soon as possible).
Although she refused to reveal any secret codes, the Germans gained enough information from them to continue sending false messages imitating her.
As a WAAF signaller, Khan had been nicknamed "Bang Away Lulu" because of her distinctively heavy-handed style, which was said to be a result of chilblains.

Some claim London failed to properly investigate anomalies which would have indicated the transmissions were sent under enemy control, in particular the change in the 'fist' (the style of the operator's Morse transmission).
However, according to M.R.D. Foot, the Sicherheitsdienst were quite adept at faking operators' fists.
The well-organised and skillful counter-espionage work of the SD under Hans Josef Kieffer is, in fact, the true reason for the intelligence failures.

Additionally, Déricourt, F Section's air-landing officer in France, literally gave SOE's secrets to the SD in Paris.
He would later claim to have been working for the Secret Intelligence Service (SIS, commonly known as MI6), without the knowledge of SOE, as part of a complex deception plan in the run-up to D-Day.

As a result, however, three more agents sent to France were captured by the Germans at their parachute landing, including Madeleine Damerment, who was later executed.
Sonya Olschanezky ('Tania'), a locally recruited SOE agent, had learnt of Inayat Khan's arrest and sent a message to London through her fiancé, Jacques Weil, telling Baker Street of her capture and warning HQ to suspect any transmissions from "Madeleine".

Colonel Maurice Buckmaster ignored the message as unreliable because he did not know who Olschanezky was.
As a result, German transmissions from Khan's radio continued to be treated as genuine, leading to the unnecessary deaths of SOE agents, including Olschanezky herself, who was executed at Natzweiler-Struthof concentration camp on 6 July 1944.
When Vera Atkins investigated the deaths of missing SOE agents, she initially confused Inayat Khan with Olschanezky (they were similar in appearance), who was unknown to her, believing Khan had been killed at Natzweiler, correcting the record only when she learned of Khan's fate at Dachau.

On 25 November 1943, Inayat Khan escaped from the SD Headquarters, along with fellow SOE agents John Renshaw Starr and Léon Faye, but was recaptured in the vicinity.
