Radiolab Presents: Anna in Somalia
This week, we are presenting a story from NPR foreign correspondent Gregory Warner and his new globe-trotting podcast Rough Translation. Mohammed was having the best six months of his life - working a job he loved, making mixtapes for his sweetheart - when the communist Somali regime perp-walked him out of his own home, and sentenced him to a lifetime of solitary confinement.  With only concrete walls and cockroaches to keep him company, Mohammed felt miserable, alone, despondent.  But then one day, eight months into his sentence, he heard a whisper, a whisper that would open up a portal to - of all places and times - 19th century Russia, and that would teach him how to live and love again.
