There was a pond in the grounds of the Red House.  He had dragged this, but without result ....

Antony listened to him carelessly, thinking his own thoughts all the time.  Medical evidence followed, but there was nothing to be got from that.  He felt so close to the truth; at any moment something might give his brain the one little hint which it wanted.  Inspector Birch was just pursuing the ordinary.  Whatever else this case was, it was not ordinary.  There was something uncanny about it.

John Borden was giving evidence.  He was on the up platform seeing a friend off by the 3.55 on Tuesday afternoon.  He had noticed a man on the platform with coat collar turned up and a scarf round his chin.  He had wondered why the man should do this on such a hot day.  The man seemed to be trying to escape observation.  Directly the train came in, he hurried into a carriage.  And so on.

“There’s always a John Borden at every murder case,” said Antony to himself.

“Have you ever seen Mark Ablett?”

“Once or twice, sir.”

“Was it he?”

“I never really got a good look at him, sir, what with his collar turned up and the scarf and all.  But directly I heard of the sad affair, and that Mr. Ablett was missing, I said to Mrs. Borden, ‘Now I wonder if that was Mr. Ablett I saw at the station?’ So then we talked it over and decided that I ought to come and tell Inspector Birch.  It was just Mr. Ablett’s height, sir.”

Antony went on with his thoughts ....

The Coroner was summing up.  The jury, he said, had now heard all the evidence and would have to decide what had happened in that room between the two brothers.  How had the deceased met his death?  The medical evidence would probably satisfy them that Robert Ablett had died from the effects of a bullet-wound in the head.  Who had fired that bullet?  If Robert Ablett had fired it himself, no doubt they would bring in a verdict of suicide, but if this had been so, where was the revolver which had fired it, and what had become of Mark Ablett?  If they disbelieved in this possibility of suicide, what remained?  Accidental death, justifiable homicide, and murder.  Could the deceased have been killed accidentally?  It was possible, but then would Mark Ablett have run away?  The evidence that he had run away from the scene of the crime was strong.  His cousin had seen him go into the room, the servant Elsie Wood had heard him quarrelling with his brother in the room, the door had been locked from the inside, and there were signs that outside the open window some one had pushed his way very recently through the shrubbery.  Who, if not Mark?  They would have then to consider whether he would have run away if he had been guiltless of his brother’s death.  No doubt innocent people lost their heads sometimes.  It was possible that if it were proved afterwards that Mark Ablett had shot his brother, it might also be proved that he was justified in so doing, and that when he ran away from his brother’s corpse he had really nothing to fear at the hands of the Law.  In this connection he need hardly remind the jury that they were not the final tribunal, and that if they found Mark Ablett guilty of murder it would not prejudice his trial in any way if and when he was apprehended ....  The jury could consider their verdict.
