At this question, the secretary’s face showed a gleam of enlightenment, as though he had detected a point which he had previously missed. He glanced at Howard Torrance for an instant as though trying to read his face; then he looked again at the girl.

“I hadn’t thought of that,” Vera admitted frankly. “But I don’t think I did.”

“You heard Mr. Torrance’s voice from time to time,” Sir Clinton continued. “I’m trying to suggest that he may have called from a distance at the same time as you heard the steps near at hand. You see, it’s essential to find out exactly when the murderer left the Maze if possible; and we can only do that by checking his movements in the Maze.”

Vera thought for a moment or two before she replied.

“I can’t recall it. You know, Sir Clinton, I was nearly out of my mind with panic. I didn’t take note of things. I couldn’t. And there’s another thing—I did notice that I couldn’t make out the directions from which sounds came. The Maze seemed to shift them about anyhow. I really couldn’t tell where Mr. Torrance was at any time when he shouted to me.”

Sir Clinton nodded.

“I’d rather have you say that than try to strain your memory to make things fit. Now, just to make sure: You really did hear the murderer’s steps—or at any rate some steps—quite close to you—on the other side of the hedge, once? And that was before you found Roger Shandon’s body?”

Vera nodded assent to both questions. To her relief, Sir Clinton turned to Stenness.

“Did you note the time when Miss Forrest got back to the house again?”

“I looked at my watch when she was telling me her story. It was then 4.42. I reached the Maze myself at 5.16.”
