Set in Darkness (Inspector Rebus #11) by Ian Rankin

On the eve of the first Scottish parliament in three hundred years, Edinburgh is a city rife with political passions and expectations. Queensbury House, the home of Scotland's new rulers, falls in the middle of John Rebus' turf, keeping him busy with ceremonial tasks. That quickly changes, however, when a long-dead body is discovered in a Queensbury House fireplace, a homeless man throws himself off a bridge - leaving behind a suitcase full of cash - and an up-and-coming politician is found murdered.
