In nearly 
two decades as a foreign correspondent, I covered stories of mass graves
 in far-flung locations in Eastern Europe  and Russia. The thought of 
them has remained lodged in my memory. 
But
 never did I expect to be covering a mass grave from modern times on my 
own doorstep; I thought Western and Northern Europe was immune from such
 horrors. Yet
 that is exactly what I came across in January this year in the small 
Irish town of Tuam in County Galway, an ugly place with its rundown 
streets and council estates.
