Vera murmured:

"I can't believe it... I can't..."

Wargrave said:

"Lombard?"

"I agree, sir, absolutely."

The judge nodded his head in a satisfied manner. He said:

"Now let us examine the evidence. To begin with, is there any reason for suspecting one particular person? Mr. Blore, you have, I think, something to say."

Blore was breathing hard. He said:

"Lombard's got a revolver. He didn't tell the truth - last night. He admits it."

Philip Lombard smiled scornfully.

He said:

"I suppose I'd better explain again."

He did so, telling the story briefly and succinctly.

Blore said sharply:

"What's to prove it? There's nothing to corroborate your story."

The judge coughed.

"Unfortunately," he said, "we are all in that position. There is only our own word to go upon."

He leaned forward.

"You have none of you yet grasped what a very peculiar situation this is. To my mind there is only one course of procedure to adopt. Is there any one whom we can definitely eliminate from suspicion on the evidence which is in our possession?"

Dr. Armstrong said quickly:

"I am a well-known professional man. The mere idea that I can be suspected of -"

Again a gesture of the judge's hand arrested a speaker before he finished his speech. Mr. Justice Wargrave said in his small clear voice:

"I, too, am a well-known person! But, my dear sir, that proves less than nothing! Doctors have gone mad before now. Judges have gone mad. So," he added, looking at Blore, "have policemen!"

Lombard said:

"At any rate, I suppose you'll leave the women out of it."

The judge's eyebrows rose. He said in the famous "acid" tone that Counsel knew so well:

"Do I understand you to assert that women are not subject to homicidal mania?"

Lombard said irritably:

"Of course not. But all the same, it hardly seems possible -"

He stopped. Mr. Justice Wargrave still in the same thin sour voice addressed Armstrong.

"I take it, Dr. Armstrong, that a woman would have been physically capable of striking the blow that killed poor Macarthur?"

The doctor said calmly:

"Perfectly capable - given a suitable instrument, such as a rubber truncheon or cosh."

"It would require no undue exertion of force?"

"Not at all."

Mr. Justice Wargrave wriggled his tortoiselike neck. He said:

"The other two deaths have resulted from the administration of drugs. That, no one will dispute, is easily compassed by a person of the smallest physical strength."

Vera cried angrily:

"I think you're mad!"

His eyes turned slowly till they rested on her. It was the dispassionate stare of a man well used to weighing humanity in the balance. She thought:

"He's just seeing me as a - as a specimen. And" - the thought came to her with real surprise - "he doesn't like me much!"

In measured tones the judge was saying:

"My dear young lady, do try and restrain your feelings. I am not accusing you." He bowed to Miss Brent. "I hope, Miss Brent, that you are not offended by my insistence that all of us are equally under suspicion?"

Emily Brent was knitting. She did not look up. In a cold voice she said:

"The idea that I should be accused of taking a fellow creature's life - not to speak of the lives of three fellow creatures - is, of course, quite absurd to any one who knows anything of my character. But I quite appreciate the fact that we are all strangers to one another and that in those circumstances, nobody can be exonerated without the fullest proof. There is, as I have said, a devil amongst us."

The judge said:

"Then we are agreed. There can be no elimination on the ground of character or position alone."

Lombard said:

"What about Rogers?"

The judge looked at him unblinkingly.

"What about him?"

Lombard said:

"Well, to my mind, Rogers seems pretty well ruled out."

Mr. Justice Wargrave said:

"Indeed, and on what grounds?"

Lombard said:

"He hasn't got the brains for one thing. And for another his wife was one of the victims."

The judge's heavy eyebrows rose once more. He said:

"In my time, young man, several people have come before me accused of the murders of their wives - and have been found guilty."

"Oh! I agree. Wife murder is perfectly possible - almost natural, let's say! But not this particular kind! I can believe in Rogers killing his wife because he was scared of her breaking down and giving him away, or because he'd taken a dislike to her, or because he wanted to link up with some nice little bit rather less long in the tooth. But I can't see him as the lunatic Mr. Owen dealing out crazy justice and starting on his own wife for a crime they both committed."

Mr. Justice Wargrave said:

"You are assuming hearsay to be evidence. We do not know that Rogers and his wife conspired to murder their employer. That may have been a false statement, made so that Rogers should appear to be in the same position as ourselves. Mrs. Rogers' terror last night may have been due to the fact that she realized her husband was mentally unhinged."

Lombard said:

"Well, have it your own way, U.N. Owen is one of us. No exceptions allowed. We all qualify."

Mr. Justice Wargrave said:

"My point is that there can be no exceptions allowed on the score of character, position, or probability. What we must now examine is the possibility of eliminating one or more persons on the facts. To put it simply, is there among us one or more persons who could not possibly have administered either Cyanide to Anthony Marston, or an overdose of sleeping draught to Mrs. Rogers, and who had no opportunity of striking the blow that killed General Macarthur?"

Blore's rather heavy face lit up. He leant forward.

"Now you're talking, sir!" he said. "That's the stuff! Let's go into it. As regards young Marston I don't think there's anything to be done. It's already been suggested that some one from outside slipped something into the dregs of his glass before he refilled it for the last time. A person actually in the room could have done that even more easily. I can't remember if Rogers was in the room, but any of the rest of us could certainly have done it."

He paused, then went on.

"Now take the woman Rogers. The people who stand out there are her husband and the doctor. Either of them could have done it as easy as winking -"

Armstrong sprang to his feet. He was trembling.

"I protest - This is absolutely uncalled for! I swear that the dose I gave the woman was perfectly -"

"Dr. Armstrong."

The small sour voice was compelling. The doctor stopped with a jerk in the middle of his sentence. The small cold voice went on.

"Your indignation is very natural. Nevertheless you must admit that the facts have got to be faced. Either you or Rogers could have administered a fatal dose with the greatest ease. Let us now consider the position of the other people present. What chance had I, had Inspector Blore, had Miss Brent, had Miss Claythorne, had Mr. Lombard of administering poison? Can any one of us be completely and entirely eliminated?" He paused. "I think not."
