Knighton had risen in concern.
“Ruth!” said Van Aldin hoarsely.
“Mrs. Kettering?”
“Killed!”
“An accident to the train?”
Van Aldin shook his head.
“No. From this it seems she has been robbed as well. They don't use the word, Knighton, but my poor girl has been murdered.”
“Oh, my God, sir!”
Van Aldin tapped the telegram with his forefinger.
“This is from the police at Nice. I must go out there by the first train.”
Knighton was efficient as ever. He glanced at the clock.
“Five o'clock from Victoria, sir.”
“That's right. You will come with me Knighton. Tell my man Archer, and pack your own things. See to everything here. I want to go round to Curzon Street.”
The telephone rang sharply, and the secretary lilted the receiver.
“Yes; who is it?”
Then to Van Aldin:
“Mr. Goby, sir.”
“Goby? I can't see him now. No – wait, we have plenty of time. Tell them to send him up.”
Van Aldin was a strong man. Already he had recovered that iron calm of his. Few people would have noticed anything amiss in his greeting to Mr. Goby.
“I am pressed for time, Goby. Got anything important to tell me?”
Mr. Goby coughed.
“The movements of Mr. Kettering, sir. You wished them reported to you.”
“Yes – well?”
“Mr. Kettering, sir, left London for the Riviera yesterday morning.”
“What?”
Something in his voice must have startled Mr. Goby. That worthy gentleman departed from his usual practice of never looking at a person to whom he was talking, and stole a fleeting glance at the millionaire.
“What train did he go on?” demanded Van Aldin.
“The Blue Train, sir.”
Mr. Goby coughed again and spoke to the clock on the mantelpiece.
“Mademoiselle Mirelle, the dancer from the Parthenon, went by the same train.”
Chapter 14. Ada Mason's Story
“I cannot repeat to you often enough. Monsieur, our horror, our consternation, and the deep sympathy we feel for you.”
Thus M. Carrege, the Juge d'Instruction, addressed Van Aldin. M. Caux, the Commissary, made sympathetic noises in his throat. Van Aldin brushed away horror, consternation, and sympathy with an abrupt gesture. The scene was the Examining Magistrate's room at Nice. Besides M. Carrege, the Commissary, and Van Aldin, there was a further person in the room. It was that person who now spoke.
“M. Van Aldin,” he said, “desires action. A swift action.”
“Ah!” cried the Commissary, “I have not yet presented you. M. Van Aldin, this is M. Hercule Poirot; you have doubtless heard of him. Although he has retired from his profession for some years now, his name is still a household word as one of the greatest living detectives.”
“Pleased to meet you, M. Poirot,” said Van Aldin, falling back mechanically on a formula that he had discarded some years ago. “You have retired from your profession?”
“That is so, Monsieur. Now I enjoy the world.”
The little man made a grandiloquent gesture.
“M. Poirot happened to be travelling on the Blue Train,” explained the Commissary, “and he has been so kind as to assist us out of his vast experience.”
The millionaire looked at Poirot keenly. Then he said unexpectedly:
“I am a very rich man, M. Poirot. It is usually said that a rich man labours under the belief that he can buy everything and every one. That is not true. I am a big man in my way, and one big man can ask a favour from another big man.”
Poirot nodded a quick appreciation.
“That is very well said, M. Van Aldin. I place myself entirely at your service.”
“Thank you,” said Van Aldin. “I can only saw call upon me at any time, and you will not find me ungrateful. And now, gentlemen, to business.”
“I propose,” said M. Carrege, “to interrogate the maid, Ada Mason. You have her here, I understand?”
“Yes,” said Van Aldin. “We picked her up in Paris in passing through. She was very upset to hear of her mistress's death, but she tells her story coherently enough.”
“We will have her in, then,” said M. Carrege.
He rang the bell on his desk, and in a few minutes Ada Mason entered the room.
She was very neatly dressed in black, and the tip of her nose was red. She had exchanged her grey travelling gloves for a pair of black suede ones. She cast a look round the Examining Magistrate's office in some trepidation, and seemed relieved at the presence of her mistress's father. The Examining Magistrate prided himself on his geniality of manner, and did his best to put her at her ease. He was helped in this by Poirot, who ted as interpreter, and whose friendly banner was reassuring to the Englishwoman.
“Your name is Ada Mason; is that right?”
“Ada Beatrice I was christened, sir,” said Mason primly.
“Just so. And we can understand, Mason, that this has all been very distressing.”
“Oh, indeed it has, sir. I have been with many ladies and always given satisfaction, I hope, and I never dreamt of anything of this kind happening in any situation where I was.”
“No, no,” said M. Carrege.
“Naturally I have read of such things, of course, in the Sunday papers. And then I always have understood that those foreign trains-” She suddenly checked her flow, remembering that the gentlemen who were speaking to her were of the same nationality as the trains.
“Now let us talk this affair over,” said M. Carrege. “There was, I understand, no question of your staying in Paris when you started from London?”
“Oh no, sir. We were to go straight through to Nice.”
“Have you ever been abroad with your mistress before?”
“No, sir. I had only been with her two months, you see.”
“Did she seem quite as usual when starting on this journey?”
“She was worried like and a bit upset, and was rather irritable and difficult to please.”
M. Carrege nodded.
“Now then. Mason, what was the first you heard of your stopping in Paris?”
“It was at the place they call the Gare de Lyon, sir. My mistress was thinking of getting out and walking up and down the platform. She was just going out into the corridor when she gave a sudden exclamation, and came back into her compartment with a gentleman. She shut the door between her carriage and mine, so that I didn't see or hear anything, till she suddenly opened it again and told me that she had changed her plans. She gave me some money and told me to get out and go to the Ritz. They knew her well there, she said, and would give me a room. I was to wait there until I heard from her, she would wire me what she wanted me to do. I had just time to get my things together and jump out of the train before it started off. It was a rush.”
“While Mrs. Kettering was telling you this, where was the gentleman?”
