Sterling's first book revisited the 1948 death of Jan Masaryk, the Czechoslovak foreign minister, which she blamed on Soviet or Czechoslovak Stalinists.
After the Stalinists killed Trotsky in a second attempt on August 20, Schüssler remained in Mexico, took a job, and continued to be active in the Mexican section of the Fourth International under his Mexican pseudonym, "Julián Suárez."
