How was intelligence work in England and the United States developing during the time just before the outbreak of WWII?

the work on the German codes continued. Stevenson wanted a computer for use in breaking the codes. Churchill wants to share intelligence with Roosevelt and feels it should be done on a daily basis. Stevenson went to America to meet with Roosevelt. He had information that Germany was researching nuclear fission and that it was possible to build an atomic bomb. They arranged for cooperation between the Federal Bureau of Investigation and British Intelligence.
