In return for this information, the Intelligence Corps allegedly allowed him to escape during a staged ambush in Dublin's South Circular Road.
The message, issued by the British Military Headquarters, stated that a "Sinn Féin" suspect named Fovargue had escaped from three Intelligence Corps officers in a car whilst en route to prison.
From Joe Kinsella's own statement to the Irish Bureau of Military History - "From the outset I personally did not place a lot of trust in him, because on the morning that he took over from me he appeared to me, to be too inquisitive about the movements of Michael Collins and the G.H.Q.
[5] Sean Kavanagh, a Kilkenny IRA man, claimed that Fovargue was put in a cell with him in Kilmainham Gaol in 1921 in order to try to extract information from him.
[7] Discovered near the corpse was a small piece of paper on which had been scribbled in blue pencil the words "Let spies and traitors beware – IRA".
Fovargue is tracked down while working out at the golf course, allowed to say the Act of Contrition, and then fatally shot by Liam Tobin (Brendan Gleeson).
