My Twin Brother's Perfect Replacement

The night before Logan is due to finalise his wedding date with his fiancée Clara, his twin takes him out for hotpot. But the man across the table eats cilantro and heaps peanut butter onto his beef without a flicker of reaction — impossible for Logan, whose peanut allergy nearly killed him as a child. When their childhood secret signal, a double-tap on the glass, goes unanswered, the truth lands like ice: this is not Logan.

At home, the impostor slips easily into the family, embracing adoptive mother Helen and joking with adoptive father Arthur. Yet when the twin mentions the peanut butter, Helen's knife slips and Arthur's smile stiffens. Both insist a herbalist cured Logan months ago — a lie the twin knows is medically impossible.

Alone behind a locked door, the twin realises the house that raised them may be hiding something far worse, and that somewhere out there the real Logan is waiting to be found.
