In the summer of 1974 a heatwave blankets Boston and Mary Pat Fennessey is trying to stay one step ahead of the bill collectors. Mary Pat has lived her entire life in the housing projects of `Southie`, the Irish American enclave that stubbornly adheres to old tradition and stands proudly apart. One night Mary Pat`s teenage daughter Jules stays out late and doesn`t come home. That same evening, a young Black man is found dead, struck by a subway train under mysterious circumstances. The two events seem unconnected. But Mary Pat, propelled by a desperate search for her missing daughter, begins turning over stones best left untouched - asking questions that bother Marty Butler, chieftain of the Irish mob, and the men who work for him, men who don`t take kindly to any threat to their business. Set against the hot, tumultuous months when the city`s desegregation of its public schools exploded in violence, Small Mercies is a superb thriller, a brutal depiction of criminality and power, and an unflinching portrait of the dark heart of American racism.
