Key passages

    Jamieson challenges Rachel's assumptions about the identity of the midnight visitor.

    Jamieson doubts Armstrong was the first intruder and thinks someone inside let him in on the night of the murder.

    Jamieson reveals his theory that the murder involved an inside accomplice.

  • I had a basket of—of silver and dishes on my arm and I was carrying the plate, because—because I was afraid I'd break it. Partway up the road a man stepped out of the bushes, and held his arm like this, spread out, so I couldn't get past.
