One Night for Love by Mary Balogh (Paperback)

Neville Wyatt, Earl of Kilbourne, awaits his new bride at the altar - when a ragged beggar woman races down the aisle instead. The cream of the ton see him stare, shocked, then declare that this is his late wife! One night of passion is all he remembers of Lily, the woman he'd wed, loved, and lost on the battlefield in Portugal.
