"For many, the trauma and humiliation were difficult to bear. This was particularly true for Chapman, a talented and successful young economist who had received a master's degree from the University of Toronto and was working at the Bureau of Dominion Statistics. Her name did not come up in the Gouzenko documents, but she knew several of the accused spies, who participated in Marxist study groups held at her home on Somerset Street in Ottawa, just a few blocks from where the Gouzenkos lived. In her testimony before the Royal Commission, Kathleen Willisher, who belonged to one of the study groups, claimed Chapman was a secret GRU contact, so the RCMP arrested her. Despite her eventual acquittal, Chapman lost her job, and the publicity was such that she felt compelled to leave Canada for several years. In the early 1960s, she took her own life." [Amy Knight, How the Cold War Began]

In their biographical sketch of Chapman, the espionage commission's final report notes:

"Miss Chapman was born in England, May 6th, 1907, and came to Canada in 1918. She is a graduate of the University of British Columbia having obtained her Bachelor's Degree in commerce and subsequently in 1931 her Master's Degree. After some intermediate employment she entered the employ of the Bank of Canada in 1940. When testifying before us, while still on the staff of the Bank, she was on loan to the Bureau of Statistics.
The name of Agatha Chapman was first mentioned in evidence by Kathleen Willisher when she deposed that she had met Eric Adams for the first time in 1942 in a study group in Ottawa when Chapman, Eric Adams, and J.S. Benning were present. It was Chapman who invited Kathleen Willisher. The subject under discussion that evening was, "socialist literature, Marxist literature I suppose you would call it." Eric Adams was in charge of the meeting. The group met regularly every three weeks until Adams left for Montreal at the end of 1944."
