He looked swiftly around to make sure no one was watching, stepped forward, and put his arms around the recusant in a quick embrace. "I'm sorry it had to go this far," he murmured, then stepped back and raised his hand in a parting salute. "If you leave now you could still make it back to the recusant Headquarters alive.

-- Edgar Allan Poe, The Pit and the Pendulum
