Twists of Fate A Pride and Prejudice Variation

What if Mr Collins shocked Elizabeth with his base conduct at the time of his proposal, thus sending her dashing out of her house, and into the arms of Mr Darcy? What if that accidental encounter was witnessed, and impropriety was assumed? What if Mr Darcy was glad of the excuse to marry his heart's desire - only to have his best hopes blasted within hours of his wedding? What if he found himself in the wrong place at the wrong time more than once? Evil rumours, an early marriage, a dreadful misunderstanding, an old secret and good intentions gone awry. What if 'I do' is not the end, but the beginning of the adventure? (The novel addresses mature themes. Given the 'early marriage' premise, the issue of growing affection and intimacy is central to the story. The relevant scenes are emotive and deeply sensual, but never explicit.)
