It’s midsummer in the Shetland Islands, the time of the white nights, when birds sing at midnight and the sun never sets. Artist Bella Sinclair throws an elaborate party to launch an exhibition of her work at The Herring House, a gallery on the beach.The party ends in farce when one the guests, a mysterious Englishman, bursts into tears and claims not to know who he is or where he’s come from. The following day the Englishman is found hanging from a rafter, and Detective Jimmy Perez is convinced that the man has been murdered. He is reinforced in this belief when Roddy, Bella’s musician nephew, is murdered, too.But the detective’s relationship with Fran Hunter may have clouded his judgment, for this is a crazy time of the year when night blurs into day and nothing is quite as it seems.
