THE MAN CALLING himself Mr. Jones was quite clearly making it up as he went along. Just as clearly, he was comfortable doing so. He did not appear to be aware that the cellar had an exit on the back alley and so, pulling Zula along with him, he went up one flight of stairs to the ground-floor landing. As they approached it he reached across his body with his free hand and clamped this over Zula’s eyes and did not let her see again until they were in a corridor. Zula knew why and didn’t fight it.
