“No, I can remember nobody who ever took the slightest interest in it. It’s not, somehow, the sort of thing that does interest people. What I mean to say is, there’s not much use in it, is there?”

Sir Clinton diverged for an instant from his usual reticence.

“It’s strange the murderer didn’t leave some trace, then. I’d have expected to find him using a thread to guide him out of the Maze—like Theseus in the labyrinth.”

He paused for a moment, then added:

“But perhaps he rolled it up as he went out, so as to leave nothing behind.”

He rose as he spoke and put his last questions.

“Do you suspect anyone in this matter, Mr. Shandon? Was there anyone in the background whom we haven’t heard about? A woman, for instance?”

Ernest Shandon seemed to ponder these queries in his dull way.

“No,” he said at last, “I don’t think so. Not to my knowledge, at least. Of course my brothers had their own affairs; but that’s to be expected in families, isn’t it? I mean, they didn’t tell me everything, of course. But bar this Shackleton business, I can’t say I ever heard anything that would fit the case. No, I can’t remember ever hearing anything of the sort.”

The Chief Constable wasted no further time.
