From the Back Cover
A Kobheerian freighter arrives at the station carrying a Cardassian passenger suffering from a medical condition known as Kalla-Nohra. Upon seeing the visitor, Major Kira (Nana Visitor) immediately arrests him, citing that the only place he could have contracted Kalla-Nohra was at Gallitepp, a Bajoran forced labor camp. Though he denies the accusation, the Cardassian, tentatively identified as a teacher, is held captive while Kira investigates his background.
A photograph from Bajoran archives reveals that this teacher is actually Gul Darhe'el, the "Butcher of Gallitepp". When Kira confronts him with the information, the Cardassian says it's true - but an even deeper secret remains!
