HAUNTED GROUND

Cutting turf in the peat bogs of his Ireland farm, Brendan McGann occasionally finds old oak beams, oxcarts or tubs of butter and cheese buried ages ago and forgotten. But he's hardly prepared for the gruesome discovery he makes one pleasant April morning: the perfectly preserved head of a woman. So begins Hart's debut thriller, which follows archeologist Cormac Maguire, maverick local detective Garret Devaney, and Nora Gavin, an American anatomist lecturing at Trinity College Medical School, as they investigate the farmer's grisly finding, which could date back quite far, given that peat bogs can preserve bodies for centuries. Cormac and Nora stay in the house of Hugh Osborne, the owner of a decaying manor who also happens to be the prime suspect in the unsolved disappearance of his wife and infant son two years ago. The accommodations are not quite the Ritz. Osborne's dour cousin, Lucy Osborne, is the housekeeper, and her son, 17-year-old Jeremy, who drinks too much, also lurks around the estate. Nora finds a filthy, dead crow on her bed, as well as broken glass littering her bathroom floor. What's going on in this malevolent household? In addition to a complex, multilayered plot that involves both contemporary and historical crimes, Hart's novel is rich in local color: evenings at the pub, the petty feuds and jealousies of the townspeople and the traditional music and folk culture of Ireland are evocatively rendered.
