A skilfully planned murder in Portugal; a clever con-game in Texas; a body washed up on the Galloway coast. What have these far-flung events in common? In a word: whisky. And not any kind of whisky, but a fine malt.

Bruce Sanderson is on a ten-day holiday in the Highlands when he encounters Iain MacNair, who begins to teach him the mysteries of blending noble malts. He soon embarks on a relationship with MacNair’s daughter Katriona but, shortly after, Macnair is murdered. Bruce begins to investigate the murder and soon finds that both he and Katriona are in the sights of a dangerous killer who will go to any lengths to protect an ingenious fraud.
