Mata Hari was held in the Saint Lazare Prison. During the coming four months she was to be interrogated fourteen times. In the first and last interrogations, she was allowed to be accompanied by her lawyer, Maitre Clunet; during the other twelve times, Mata Hari sat alone across from Captain Bouchardon. The last interrogation was held on 21 June 1917. On 24 and 25 July, however, the trial by French court marshal took place behind closed doors. Seven jury members had to conclude, based on Bouchardon's report, whether or not she was guilty of pro-German espionage activities. The final judgement was unanimous: guilty! Mata Hari was sentenced to death. An appeal failed, as did the Dutch Ministry of Foreign Affairs' attempt to obtain Mata Hari a reprieve.
 
It was cold on Monday, 15 October 1917. The eye of the day started shining at eleven minutes past six. Four minutes later, twelve rifle shots shattered the morning stillness.
