Olen Steinhauer (born June 21, 1970 in Baltimore) is an American writer of spy fiction novels, including The Tourist, part of the Milo Weaver series, and the Yalta Boulevard Sequence.

[citation needed] After graduation, Steinhauer received a year-long Fulbright grant to write a novel in Romania about the Romanian Revolution.

It was called Tzara's Monocle, and when he moved to New York City afterward, he used that manuscript to secure a literary agent.

His 2009 CIA novel, The Tourist, received positive reviews and is being developed for film by Sony Pictures Entertainment for Doug Liman to direct.

The Bridge of Sighs was the first in a five-book series of thrillers chronicling the evolution of a fictional Eastern European country situated in the historical location of Ruthenia (now part of Ukraine) during the Cold War, with one book for each decade.
