Margorie "Mo" Mowlam, the straight-talking, no-nonsense Englishwoman who was instrumental in brokering a peace deal between the IRA, Sinn Féin, and other factions fighting in Northern Ireland died in 2005 of a cancer she kept concealed from most of her family, friends, PM Tony Blair, and the government agencies she worked for. While a scattered few felt burned by the revelation that Mo's cancer was malignant -- not benign like she originally told everyone -- almost everyone understood that she kept the secret so she would be left alone in peace to do the job she felt she'd been born to do: help ensure peace in Northern Ireland, which had been nothing but a dream to many until she took it up as her cause.
