He was stopped by a warning gesture from Poirot. The sound of a key being turned in the lock of the other door which led to the front hall and the staircase to the upper floors of the house was heard. As the two men turned, it opened slowly, and Tredwell, the butler, stood in the doorway.
"I beg your pardon, sir," said Tredwell as he came into the room and shut the door behind him. "The master told me to lock this door, as well as the other one leading from this room, until you arrived. The master..." He stopped on seeing the motionless figure of Sir Claud in the chair.
"I am afraid your master is dead," Poirot told him. "May I ask your name?"
"Tredwell, sir." The servant moved to the front of the desk, looking at the body of his master. "Oh dear. Poor Sir Claud!" he murmured. Turning to Poirot, he added, "Do please forgive me, sir, but it's such a shock. May I ask what happened? Is it - murder?"
"Why should you ask that?" said Poirot.
Lowering his voice, the butler replied, "There have been strange things happening this evening, sir."
"Oh?" exclaimed Poirot, as he exchanged glances with Hastings. "Tell me about these strange things."
"Well, I hardly know where to begin, sir," Tredwell replied. "I - I think I first felt that something was wrong when the Italian gentleman came to tea."
"The Italian gentleman?"
"Dr Carelli, sir."
"He came to tea unexpectedly?" asked Poirot.
"Yes, sir, and Miss Amory asked him to stay for the weekend, seeing as how he was a friend of Mrs Richard's. But if you ask me, sir -"
He stopped, and Poirot gently prompted him. "Yes?"
"I hope you will understand, sir," said Tredwell. "that it is not my custom to gossip about the family. But seeing that the master is dead..."
He paused again, and Poirot murmured sympathetically, "Yes, yes, I understand. I am sure you were very attached to your master." Tredwell nodded, and Poirot continued, "Sir Claud sent for me in order to tell me something. You must tell me all you can."
"Well, then," Tredwell responded, "in my opinion, sir, Mrs Richard Amory did not want the Italian gentleman asked to dinner. I observed her face when Miss Amory gave the invitation."
"What is your own impression of Dr Carelli?" asked Poirot.
"Dr Carelli, sir," replied the butler rather haughtily, "is not one of us."
Not quite understanding Tredwell's remark, Poirot looked inquiringly at Hastings, who turned away to hide a smile. Throwing his colleague a glance of mild reproof, Poirot turned again to Tredwell. The butler's countenance remained perfectly serious.
"Did you feel," Poirot queried, "that there was something odd about Dr Carelli's coming to the house in the way that he did?"
"Precisely, sir. It wasn't natural, somehow. And it was after he arrived that the trouble began, with the master telling me earlier this evening to send for you, and giving orders about the doors being locked. Mrs Richard, too, hasn't been herself all the evening. She had to leave the dinner-table. Mr Richard, he was very upset about it."
"Ah," said Poirot, "she had to leave the table? Did she come into this room?"
"Yes, sir," Tredwell replied.
Poirot looked around the room. His eye alighted on the handbag which Lucia had left on the table. "One of the ladies has left her bag, I see," he observed, as he picked it up.
Moving closer to him to look at the handbag, Tredwell told Poirot, "That is Mrs Richard's, sir."
"Yes," Hastings confirmed. "I noticed her laying it down there just before she left the room."
"Just before she left the room, eh?" said Poirot. "How curious." He put the bag down on the settee, frowned perplexedly, and stood there, apparently lost in thought.
"About locking the doors, sir," Tredwell continued after a brief pause. "The master told me -"
Suddenly starting out of his reverie, Poirot interrupted the butler. "Yes, yes, I must hear all about that. Let us go through here," he suggested, indicating the door nearer to the front of the house.
Tredwell went to the door, followed by Poirot. Hastings, however, declared rather importantly, "I think I'll stay here."
Poirot turned, and regarded Hastings quizzically. "No, no, please come with us," he requested his colleague.
"But don't you think it better -" Hastings began, when Poirot interrupted him, now speaking solemnly and meaningfully.
"I need your co-operation, my friend," he said.
"Oh, well, of course, in that case -"
The three men left the room together, closing the door behind them. No more than a few seconds later, the other door leading to the hallway was opened cautiously and Lucia entered surreptitiously. After a hurried glance around the room, as though to assure herself that there was no one there, she approached the round table in the center of the room and picked up Sir Claud's coffee-cup. A shrewd, hard look came into her eyes which belied their customary innocent appearance, and she looked suddenly a good deal older.
Lucia was still standing with the cup in her hand, as though undecided what to do, when the other door leading to the front of the house opened and Poirot entered the library alone.
"Permit me, madame," said Poirot, causing Lucia to start violently. He moved across to her and took the cup from her hand with the air of one indulging in a gesture of simple politeness.
"I - I - came back for my bag," Lucia gasped.
"Ah, yes," said Poirot. "Now, let me see, where did I observe a lady's handbag? Ah yes, over here." He went to the settee, picked up the bag, and handed it to Lucia.
"Thank you so much," she said, glancing around distractedly as she spoke.
"Not at all, madame."
After a brief nervous smile at Poirot, Lucia quickly left the room. When she had gone, Poirot stood quite still for a moment or two, and then picked up the coffee-cup. After smelling it cautiously, he took from his pocket a test-tube, poured some of the dregs from Sir Claud's cup into it, and sealed the tube. Replacing it in his pocket, he then proceeded to look around the room, counting the cups aloud. "One, two, three, four, five, six. Yes, six coffee-cups."
A perplexed frown was beginning to gather between Poirot's brows, when suddenly his eyes shone with that green light that always betokened inward excitement. Moving swiftly to the door through which he had recently entered, he opened it and slammed it noisily shut again, and then darted to the French windows, concealing himself behind the curtains. After a few moments the other door to the hallway opened once more, and Lucia entered again, this time even more cautiously than before, appearing to be very much on her guard. Looking about her in an attempt to keep both doors in her sight, she snatched up the coffee-cup from which Sir Claud had drunk and surveyed the entire room.
Her eye alighted on the small table near the door to the hall, on which there stood a large bowl containing a house plant. Moving to the table, Lucia thrust the coffee-cup upside down into the bowl. Then, still watching the door, she took one of the other coffee-cups and placed it near Sir Claud's body. She then moved quickly to the door, but as she reached it, the door opened and her husband Richard entered with a very tall, sandy-haired man in his early thirties, whose countenance, though amiable, had an air of authority about it. The newcomer was carrying a Gladstone bag.
"Lucia!" Richard exclaimed, startled. "What are you doing here?"
"I - I - came to get my handbag," Lucia explained. "Hello, Dr Graham. Excuse me, please," she added, hurrying past them.
As Richard watched her go, Poirot emerged from behind the curtains, approaching the two men as though he had just entered the room by the other door.
"Ah, here is Monsieur Poirot. Let me introduce you. Poirot, this is Dr Graham. Kenneth Graham." Poirot and the doctor bowed to each other, and Dr Graham went immediately to the body of the dead scientist to examine it, watched by Richard. Hercule Poirot, to whom they paid no further attention, moved about the room, counting the coffee-cups again with a smile.
"One, two, three, four, five," he murmured. "Five, indeed."
A light of pure enjoyment lit up Poirot's face, and he smiled in his most inscrutable fashion. Taking the test-tube out of his pocket, he looked at it and slowly shook his head.
Meanwhile, Dr Graham had concluded a cursory examination of Sir Claud Amory's body.
"I'm afraid," he said to Richard, "that I shan't be able to sign a death certificate. Sir Claud was in perfectly healthy condition, and it seems extremely unlikely to me that he could have suffered a sudden heart attack. I fear we shall have to find out what he had eaten or drunk in his last hours."
"Good heavens, man, is that really necessary?" asked Richard, with a note of alarm in his voice. "He hadn't eaten or drunk anything that the rest of us didn't. It's absurd to suggest -"
"I'm not suggesting anything," Dr Graham interrupted, speaking firmly and with authority. "I'm telling you that there will have to be an inquest, by law, and that the coroner will certainly want to know the cause of death. At present I simply do not know what caused Sir Claud's death. I'll have his body removed, and I'll arrange for an autopsy to be done first thing tomorrow morning as a matter of urgency. I should be able to get back to you later tomorrow with some hard facts."
He left the room swiftly, followed by a still expostulating Richard. Poirot looked after them, and then assumed a puzzled expression as he turned to look again at the body of the man who had called him away from London with such urgency in his voice.
"What was it you wanted to tell me, my friend? I wonder. What did you fear?" he thought to himself. "Was it simply the theft of your formula, or did you fear for your life as well? You relied on Hercule Poirot for help. You called for help too late, but I shall try to discover the truth."
Shaking his head thoughtfully, Poirot was about to leave the room when Tredwell entered.
"I've shown the other gentleman to his room, sir," he told Poirot. "May I take you to yours, which is the adjoining one at the top of the stairs? I've also taken the liberty of providing a little cold supper for you both, after your journey. On the way upstairs I'll show you where the dining-room is."
Poirot inclined his head in polite acceptance.
"Thank you very much, Tredwell," he said. "Incidentally, I am going to advise Mr Amory most strongly that this room should be kept locked until tomorrow, when we should have further information about this evening's distressing occurrence. Would you be so kind as to make it secure after we leave it now?"
"Most certainly sir, if that is your wish," replied Tredwell as Poirot preceded him out of the library.
Chapter 8
When Hastings came down to breakfast late the following morning, after having slept long and well, he found himself eating alone. From Tredwell he learned that Edward Raynor had breakfasted much earlier, and had gone back to his room to put some of Sir Claud's papers in order, that Mr and Mrs Amory had had breakfast in their suite of rooms and had not yet appeared, and that Barbara Amory had taken a cup of coffee out into the garden, where she was presumably still sunning herself. Miss Caroline Amory had ordered breakfast in her room, pleading a slight headache, and Tredwell had not seen her subsequently.
"Have you caught sight of Monsieur Poirot at all this morning, Tredwell?" Hastings asked, and was told that his friend had risen early and had decided to take a walk to the village.
"I understood Monsieur Poirot to say that he had some business to conduct there," Tredwell added.
After finishing a lavish breakfast of bacon, sausage and eggs, toast and coffee, Hastings returned to his comfortable room on the first floor, which offered a splendid view of part of the garden and, for a few minutes which Hastings found rewarding, of the sun-bathing Barbara Amory as well. It was not until Barbara had come indoors that Hastings settled down in an arm-chair with that morning's Times, which had of course gone to press too early to contain any mention of Sir Claud Amory's death the previous evening.
Hastings turned to the editorial page and began to read. A good half-hour later, he awakened from a light slumber to find Hercule Poirot standing over him.
"Ah, mon cher, you are hard at work on the case, I see," Poirot chuckled.
"As a matter of fact, Poirot, I was thinking about last night's events for quite some time," Hastings asserted. "I must have dozed off."
"And why not, my friend?" Poirot assured him. "Me, I have been thinking about the death of Sir Claud as well, and, of course, the theft of his so important formula. I have, in fact, already taken some action, and I am expecting at any minute a telephone message to tell me if a certain suspicion of mine is correct or not."
"What or whom do you suspect, Poirot?" Hastings asked eagerly.
Poirot looked out of the window before replying. "No, I do not think I can reveal that to you at this stage of the game, my friend," he replied mischievously. "Let us just say that, as the magicians on the stage like to assure us, the quickness of the hand deceives the eye."
"Really, Poirot," Hastings exclaimed, "you can be extremely irritating at times. I do think you ought to at least let me know whom you suspect of having stolen the formula. After all, I might be able to help you by -"
Poirot stopped his colleague with an airy gesture of his hand. The little detective was now wearing his most innocent expression and gazing out of the window, meditatively, into the far distance.
"You are puzzled, Hastings?" he asked. "You are wondering to yourself why I do not launch myself in pursuit of a suspect?"
"Well - something of the kind," Hastings admitted.
"It is no doubt what you would do, if you were in my place," observed Poirot complacently. "I understand that. But I am not of those who enjoy rushing about, seeking a needle in a hay-stack, as you English say. For the moment, I am content to wait. As to why I wait - eh bien, to the intelligence of Hercule Poirot things are sometimes perfectly clear which are not at all clear to those who are not so greatly gifted."
