Worse Angels - Laird Barron

Ex-majordomo and bodyguard to an industrial tycoon-cum-U.S. senator, Badja Adeyemi is in hiding and shortly on his way to a jail cell or a grave, depending on who finds him first. In his final days as a free man, he hires Isaiah Coleridge to tie up a loose end: the suspicious death of his nephew four years earlier. Coleridge and his investigative partner, Lionel Robard, find themselves in the upper reaches of New York State. At the epicentre of it all is the site of a stalled supercollider project, an immense subterranean construction that may have an even deeper, more insidious purpose.
