Hede Massing describes a Soviet "rezident" in the United States named "Bill Grinke," "Bill," and "Walter Grinke," whom she describes as a "pedestrian" man, looking about 40 years old, who took her on from Valentin Markin at the end of 1934. When Massing reported her encounters with Noel Field, she was reporting to "Bill": she had met Field through "Daily Worker" journalist Marguerite Young. By "May or June 1935," another "rezident" named "Fred" had taken over from "Bill," at which point she began to "develop" Field. In January or February 1937, just before Ignace Reiss defected from the Soviet underground, Massing received an assignment to spy on Ludwig Lore, and "Bill" resumed her management.
