“As we drifted away from the Tower Bridge, I saw a single silhouette standing against the bright lamplight. Even now when I was nearly asleep, I could recognise her. Her shoulders were hunched up as if she was upset. Whether she was upset that she had nearly killed me or that she had let me get away, I was unsure. Then she turned around and walked to join the other silhouettes standing in a group farther back. Now I could not see which one was Rose – they were all joint together to make one.”
