Matthew Chamberlain is on his way to opera stardom, with contracts at Covent Garden and around the world, but a concert in Sweden and the two women he meets there threaten to destroy his career as well as his relationship with his girlfriend. Signe Larsson has one desire in life, to devote herself to her religion by enrolling in a closed order of nuns. Her passion for her Lord is rocked by a different passion for an English bass-baritone singing the part of Christ in Bach's St Matthew Passion. Their mutual attraction sparks a series of events which disrupt their respective lives completely, upsetting their plans and throwing their emotions into turmoil. How can Matt save his career? How can he reconcile his attraction to three very different women? How can Signe devote herself to God when she is haunted by a physical desire to a man she hardly knows? Set in Sweden, Paris and London against a background of art, music and religious iconography, Matt's Passion explores desire, obsession, belief and morality for two people prey to the natural yearnings of youth and the dictates of conscience.
