Glen Ishard: the idyllic Scottish home of ex-rock star Nick Mackenzie and his exotic wife, Alusha. It is a haven of peace and security after all the years on the road, until the day a small plane with a deadly chemical cargo flies off course. In the tragic aftermath, Daisy Field, environmental campaigner, picks up the trail. Abrasive and idealistic, she's determined to fight the "profits before safety" attitude of the agrochemical industry. But to win she needs Nick's millions, and Nick is facing difficulties of his own. From the wilds of Scotland to the corridors of power in London and Chicago, from Madison Square Garden to a seedy security firm in south London, Requiem pulls Daisy into a struggle against apathy, sabotage, and dirty tricks.
