In 2006, historian Michael T. Foy published a book, ''Michael Collins's Intelligence War: The Struggle Between The British and the IRA 1919–1921'', in which he suggested that Childers might have been a spy for the British during the
Irish War of Independence. Foy speculated that she had volunteered for British intelligence before the couple moved to Ireland in 1918. The claim was described by reviewers in Irish newspapers as "dramatic", "sensational" and "a bottle of smoke". The author had discovered in
The National Archives a series of intelligence reports to indicate that a woman with high-level access to
Sinn Féin had been passing intelligence to British forces. However, the name of the agent had been obscured by blue pencil.
Nessa Childers, the daughter of Childers' son President Erskine Hamilton Childers, dismissed the evidence as "circumstantial", saying in a television interview that "it just doesn't fit with her character". She questioned the evidence that the spy was female and noted: "Up until the day she died she had photographs of
Liam Mellows, Liam Brady and
Rory O'Connor on her bedside and she revered them. It doesn't follow that such a person could have put those people's lives at risk." ==See also==
