Charlotte St. John is a successful lawyer, but her personal life has been less fortunate. She's never found true love and is resigned to being alone, until one day, a handsome stranger stumbles into her office, barely conscious and suffering from amnesia. Charlotte takes pity on him and nurses him back to health, and as he recovers, she finds herself falling for him.
The man, whose name is John Smith, can't remember anything about his past, and Charlotte is the only person he trusts. As they spend time together, they grow closer, and John falls in love with Charlotte, too.
But just as their relationship starts to blossom, John's true identity is revealed: he's already married, not just once, but twice. He's a bigamist, and he didn't even know it.
Charlotte is devastated, but she can't help feeling sympathetic towards John, who genuinely had no idea that he was breaking the law. She decides to take on his case and defend him against the bigamy charges, arguing that his memory loss has wiped out his former personality.
As she investigates his past, Charlotte uncovers stunning revelations about John's life and the women he's married. It turns out that both of his wives knew he was a bigamist and had discovered the truth months before. They had even secretly plotted his violent downfall and were waiting for the right opportunity to strike.
Charlotte is shocked and saddened by this new development, but she remains determined to clear John's name and help him start over fresh. As she works to unravel the mystery of John's past, she finds herself drawn into a dangerous web of deceit and betrayal, where nothing is as it seems.
Ultimately, Charlotte must decide whether to stand by John, even though he deceived her, or walk away and start over on her own. The Wives He Forgot is a story about love, forgiveness, and the power of second chances.
