Old Town, Edinburgh. In a squalid tenement where poverty, rats, and disease are rampant, a young woman who worked in a local tavern lies dying. Just another number and bound for a pauper's grave in Greyfriars Kirkyard. A boy found standing in his mother's blood... Alone, his grandmother the only family left, young Angus Brodie hides in the shadows nearby, the bronze medallion his dying mother pressed into his hand clenched in a tight fist as the constables carry her body from the tenement. And a name overheard—the man who was there that night, seen by the woman who collected the rents. A vow made. A promise to be kept... As his mother lay dying, Angus Brodie vowed that he would find the one responsible for her death, no matter how long it took.
