When Conan turned, in compliance with Thalis's request, to glare at the doorway opposite, Natala had been standing just behind him, close to the side of the Stygian. The instant the Cimmerian's back was turned, Thalis, with a pantherish quickness almost incredible, clapped her hand over Natala's mouth, stifling the cry she tried to give. Simultaneously the Stygian's other arm was passed about the blond girl's supple waist, and she was jerked back against the wall, which seemed to give way as Thalis' shoulder pressed against it. A section of the wall swung inward, and through a slit that opened in the tapestry Thalis slid with her captive, just as Conan wheeled back.
Inside was utter blackness as the secret door swung to again. Thalis paused to fumble at it for an instant, apparently sliding home a bolt, and as she took her hand from Natala's mouth to perform this act, the Brythunian girl began to scream at the top of her voice. Thalis's laugh was like poisoned honey in the darkness.
