Martta Koskinen

Koskinen was first imprisoned in Kotka in 1933 for revolutionary activity with several other women who had sided with the Reds, and had been sentenced to prison for treason.

Koskinen was also accused of "membership in a criminal organization" (Finnish Communist Party) and writing "clandestine literature".

She was able to continue her activities for a long time, since the Finnish Police never suspected her; she appeared too obvious for a spy: tall, visible, loud-voiced, a two-time prior prisoner, and a known communist.

[citation needed] During the Continuation War, Koskinen worked as a messenger and spy for the underground Finnish Communist Party.

One of the witnesses for the prosecutor was the infiltrator Kerttu Nuorteva, who saved her own life by testifying against Koskinen.

Minister Väinö Tanner and his wife Linda attempted to have Koskinen's sentence commuted to life imprisonment because of their personal convictions against the death penalty.

According to Olle Leino, Koskinen's last words were death to Risto Ryti, Väinö Tanner and Mannerheim.
