The Recollection Thief (2007)

Approximately a month prior to the death of the first Croatian president and in the wake of parliamentary elections in December 1999, Juraj Fran Krsto Križanić, a diplomat from the Croatian embassy in Paris is reported as missing. The case is taken over by special agent Gawain Skok, a PTSD-ridden war veteran, who believes that case might take away some of his trauma. However, over the course of the investigation, Skok starts recieving strange e-mails, seemingly sent to him from Križanić's account, which relate his disappearence to the recent murder of a young woman.
