Historian Jeff Kisseloff questions Haynes and Klehr's conclusion that Vassiliev's notes support Hede Massing's story about talking to Hiss at a party in 1935 about recruiting their mutual friend and host Noel Field into the communist underground. According to Kisseloff, "all that the files Vassiliev saw really indicate is that she was telling yet another version of her story in the 1930s. Haynes and Klehr never consider that, as an agent in Washington, D.C., who was having little success in the tasks assigned to her, she may have felt pressure back then to make up a few triumphs to reassure her superiors." Kisseloff also disputes Haynes and Klehr's linking of Hiss with former Treasury Department official Harold Glasser, who they allege was a Soviet agent. Finally, Kisseloff states that some of the evidence compiled by Haynes and Klehr actually tends to exonerate rather than convict Hiss. For example, their book cites a KGB report from 1938 in which Iskhak Akhmerov, New York station chief, writes, "I don't know for sure who Hiss is connected with." Haynes and Klehr also claim that Hiss was the agent who used the cover name "Doctor". According to Soviet sources, however, "Doctor" was a middle-aged Bessarabian Jew who was educated in Vienna.
