"Charles Kent's?"

As I was returning from my round the following morning, I was hailed by Inspector Raglan. I pulled up, and the inspector mounted on the step.

"Good morning, Dr Sheppard," he said. "Well, that alibi is all right enough."

"Charles Kent's. The barmaid at the Dog and Whistle, Sally Jones, she remembers him perfectly. Picked out his photograph from among five others. It was just a quarter to ten when he came into the bar, and the Dog and Whistle is well over a mile from Fernly Park. The girl mentions that he had a lot of money on him -- she saw him take a handful of notes out of his pocket. Rather surprised her, it did, seeing the class of fellow he was, with a pair of boots clean dropping off him. That's where that forty pounds went right enough."

"Obstinate as a mule he is. I had a chat with Hayes at Liverpool over the wire this morning."

"Hercule Poirot says he knows the reason the man went there that night," I observed.

"The man still refuses to give an account of his visit to Fernly?"

I felt a distinct pleasure in passing on my own discomfiture.

"Who told you that?"

"But gone here," he said. "I've thought so for some time. Poor old chap, so that's why he had to give up and come down here. In the family, very likely. He's got a nephew who's quite off his crumpet."

"Poirot has?" I said, very surprised.

"Yes. Hasn't he ever mentioned him to you? Quite docile, I believe, and all that, but mad as a hatter, poor lad."

Really, Caroline is amazing. She never rests until she knows the last details of everybody's family secrets. Unfortunately, I have never been able to instil into her the decency of keeping them to herself.

Then a grin overspread his weaselly countenance and he tapped his forehead significantly.

Raglan stared at me for a moment or two uncomprehendingly.

Again a grin showed itself on Inspector Raglan's face. "Your sister. Miss Sheppard, she told me all about it."

"Yes," I said maliciously. "He says he went there because he was born in Kent."

"Does he?" cried the inspector eagerly.

"Seems quite O. K., doesn't it?" said the inspector rather gloomily. "A chap can't be murdering someone in one place when he's drinking in the bar in another place a mile away."

"Might as well, I suppose. After all, even if he is a bit balmy, it was a useful dp he gave me about those fingerprints. He's got a bee in his bonnet about the man Kent, but who knows -- there may be something useful behind it."

Poirot received us with his usual smiling courtesy. He listened to the information we had brought him, nodding his head now and then.

"Are you going to release him?"

"Jump in. Inspector," I said, opening the door of the car. "We'll go up to The Larches together, and acquaint our Belgian friend with the latest news."

"Don't see what else we can do. We can't very well hold him for obtaining money on false pretences. Can't prove a ruddy thing." The inspector tossed a match into the grate in a disgruntled fashion. Poirot retrieved it and put it neatly in a little receptacle designed for the purpose. His action was purely mechanical. I could see that his thoughts were on something very different.

"What I say. I should not release him yet."

"I think probably not -- but one cannot be certain yet."

Poirot raised a hand protestingly.

"But haven't I just told you --?"

"Well, we've got proof enough of that. We've got Miss Flora Ackroyd's evidence."

"Mais oui, mais oui. I heard. I am not deaf -- or stupid, thank the good God! But you see, you approach the matter from the wrong -- the wrong -- premises, is not that the word?"

"I don't see how you make that out. Look here, we know Mr Ackroyd was alive at a quarter to ten. You admit that, don't you?"

"If I were you," he said at last, "I should not release the man Charles Kent yet."

"What do you mean?" Raglan stared at him.

Poirot looked at him for a moment, then shook his head with a quick smile. "I admit nothing that is not -- proved?

"You don't think he can have had anything to do with the murder, do you?"

The inspector stared at him heavily.

"That she said goodnight to her uncle? But me -- I do not always believe what a young lady tells me -- no, not even when she is charming and beautiful."

"Precisely." And still the inspector stared.

"You think she'd been up to her uncle's bedroom? Well, why not? Why should she lie about it?"

"Ah! that is just the question. It depends on what she was doing there, does it not?"

"But those stairs only lead to Mr Ackroyd's bedroom."

"I suggest nothing," said Poirot. "But I will remind you of this. Life was not very easy for that mother and daughter. There were bills -- there was constant trouble over small sums of money. Roger Ackroyd was a peculiar man over money matters. The girl might be at her wits' end for a comparatively small sum. Figure to yourself then what happens. She has taken the money, she descends the little staircase. When she is half-way down she hears the chink of glass from the hall. She has not a doubt of what it is -- Parker coming to the study. At all costs she must not be found on the stairs -- Parker will not forget it, he will think it odd. If the money is missed, Parker is sure to remember having seen her come down those stairs. She has just time to rush down to the study door -- with her hand on the handle to show that she has just come out, when Parker appears in the doorway. She says the first thing that comes into her head, a repetition of Roger Ackroyd's orders earlier in the evening, and then goes upstairs to her own room."

"The stairs?"

"No." Poirot's voice rang out with sudden sharpness. "That is just what he did not see. I satisfied myself of that by a little experiment the other day -- you remember, doctor? Parker saw her outside the door, with her hand on the handle. He did not see her come out of the room."

"But -- where else could she have been?"

"That is my little idea -- yes."

"You mean -- the money? Hang it all, you don't suggest that it was Miss Ackroyd who took that forty pounds?"

"Perhaps on the stairs."

"But hang it all, man, Parker saw her coming out of the door."

"Yes, but later," persisted the inspector, "she must have realized the vital importance of speaking the truth? Why, the whole case hinges on it!"

"Afterwards," said Poirot drily, "it was a little difficult for Mademoiselle Flora. She is told simply that the police are here and that there has been a robbery. Naturally she jumps to the conclusion that the theft of the money has been discovered. Her one idea is to stick to her story. When she learns that her uncle is dead she is panic-stricken. Young women do not faint nowadays, monsieur, without considerable provocation. Eh bien! there it is. She is bound to stick to her story, or else confess everything. And a young and pretty girl does not like to admit that she is a thief -- especially before those whose esteem she is anxious to retain."

"The possibility has been in my mind from the first," admitted Poirot. "I was always convinced that Mademoiselle Flora was hiding something from us. To satisfy myself, I made the little experiment I told you of. Dr Sheppard accompanied me."

Raglan brought his fist down with a thump on the table.

"I'll not believe it," he said. "It's -- it's not credible. And you -- you've known this all along?"

On inquiry for Miss Ackroyd, we were shown into the billiard room. Flora and Major Hector Blunt were sitting on the long window seat.

"Mon ami," said Poirot apologetically, "as I told you at the time, one must say something."

I acquiesced willingly.

"Certainly. Dr Sheppard will drive us up in his car."

"A test for Parker, you said it was," I remarked bitterly.

"Good-morning, Miss Ackroyd," said the inspector. "Can we have a word or two alone with you?"

Blunt got up at once and moved to the door.

"What is it?" asked Flora nervously. "Don't go. Major Blunt. He can stay, can't he?" she asked, turning to the inspector.

"There's only one thing for it," he declared. "We must tackle the young lady right away. You'll come up to Fernly with me, M. Poirot?"

The inspector rose.

Flora looked keenly at him. I saw her face grow whiter. Then she turned and spoke to Blunt. "I want you to stay -- please -- yes, I mean it. Whatever the inspector has to say to me, I'd rather you heard it."

"That's as you like," said the inspector drily. "There's a question or two it's my duty to put to you, miss, but I'd prefer to do so privately, and I dare say you'd prefer it also."

Raglan shrugged his shoulders.

"Well, if you will have it so, that's all there is to it. Now, Miss Ackroyd, M. Poirot here has made a certain suggestion to me. He suggests that you weren't in the study at all last Friday night, that you never saw Mr Ackroyd to say goodnight to him, that instead of being in the study you were on the stairs leading down from your uncle's bedroom when you heard Parker coming across the hall." Flora's gaze shifted to Poirot. He nodded back at her.

"The money?" said Blunt sharply.

Then Flora drew herself up and spoke. "M. Poirot is right. I took that money. I stole. I am a thiefyes, a common, vulgar little thief. Now you know! I am glad it has come out. It's been a nightmare, these last few days!" She sat down suddenly and buried her face in her hands. She spoke huskily through her fingers. "You don't know what my life has been since I came here. Wanting things, scheming for them, lying, cheating, running up bills, promising to pay oh! I hate myself when I think of it all! That's what brought us together, Ralph and I. We were both weak! I understood him, and I was sorry -- because I'm the same underneath. We're not strong enough to stand alone, either of us. We're weak, miserable, despicable things."

"Mademoiselle, the other day, when we sat round the table, I implored you to be frank with me. What one does not tell to Papa Poirot he finds out. It was that, was it not? See, I will make it easy for you. You took the money, did you not?"

There was a silence which lasted for at least a minute.

"Ralph," said Blunt. "I see -- always Ralph."

"You don't understand," said Flora hopelessly. "You never will." She turned to the inspector.

She looked at Blunt and suddenly stamped her foot. "Why do you look at me like that -- as though you couldn't believe? I may be a thief- but at any rate I'm real now. I'm not lying any more. I'm not pretending to be the kind of girl you like, young and innocent and simple. I don't care if you never want to see me again. I hate myself, despise myselfbut you've got to believe one thing, if speaking the truth would have made things better for Ralph, I would have spoken out. But I've seen all along that it wouldn't be better for Ralph -- it makes the case against him blacker than ever. I was not doing him any harm by sticking to my lie."

"I admit everything; I was at my wits' end for money. I never saw my uncle that evening after he left the dinnertable. As to the money, you can take what steps you please. Nothing could be worse than it is now!"

Suddenly she broke down again, hid her face in her hands, and rushed from the room.

Poirot was after him in a flash. He caught the other up in the hall.

"Well," said the inspector in a flat tone, "so that's that." He seemed rather at a loss what to do next.

Blunt came forward.

"Inspector Raglan," he said quietly, "that money was given to me by Mr Ackroyd for a special purpose. Miss Ackroyd never touched it. When she says she did, she is lying with the idea of shielding Captain Paton. The truth is as I said, and I am prepared to go into the witness-box and swear to it." He made a kind of jerky bow, then turning abruptly he left the room.

"Monsieur -- a moment, I beg of you, if you will be so good."

"It is this," said Poirot rapidly: "I am not deceived by your little fantasy. No, indeed. It was truly Miss Flora who took the money. All the same it is well imagined what you say -- it pleases me. It is very good what you have done there. You are a man quick to think and to act."

"Well, sir?" Blunt was obviously impatient. He stood frowning down on Poirot.

"I'm not in the least anxious for your opinion, thank you," said Blunt coldly.

Blunt had shown several signs of restlessness whilst Poirot was speaking, but the closing words seemed to rivet his attention.

"What d'you mean by that?" he said sharply.

He made once more as though to pass on, but Poirot, not at all offended, laid a detaining hand on his arm.

"You think that she loves the Capitaine Ralph Paton -- but I, Hercule Poirot, tell you that that is not so. Mademoiselle Flora accepted Captain Paton to please her uncle, and because she saw in the marriage a way of escape from her life here which was becoming frankly insupportable to her. She liked him, and there was much sympathy and understanding between them. But love -- no! It is not Captain Paton Mademoiselle Flora loves."

"Ah! but you are to listen to me. I have more to say. The other day I spoke of concealments. Very well, all along I have seen what you are concealing. Mademoiselle Flora, you love her with all your heart. From the first moment you saw her, is it not so? Oh! let us not mind saying these things -- why must one in England think it necessary to mention love as though it were some disgraceful secret? You love Mademoiselle Flora. You seek to conceal that fact from all the world. That is very good -- that is as it should be. But take the advice of Hercule Poirot -- do not conceal it from mademoiselle herself."

I saw the dark flush under his tan.

"My sister told me the other night," I said encouragingly, "that Flora had never cared a penny piece for Ralph Paton, and never would. My sister is always right about these things."

"If you doubt me, ask her yourself, monsieur. But perhaps you no longer care to -- the affair of the money --"

"You have been blind, monsieur. Blind! She is loyal, the little one. Ralph Paton is under a cloud, she is bound in honour to stick by him."

"Think I'd hold that against her? Roger was always a queer chap about money. She got in a mess and didn't dare tell him. Poor kid. Poor lonely kid."

Poirot looked thoughtfully at the side door.

Blunt ignored my well-meant offers. He spoke to Poirot. "D'you really think --" he began, and stopped.

He is one of those inarticulate men who find it hard to put things into words. Poirot knows no such disability.

Blunt gave a sound like an angry laugh.

I felt it was time I put in a word to help on the good work.

"What the devil do you mean?" asked Blunt.

"I've been every kind of a fool," said Blunt abruptly. "Rum conversation we've been having. Like one of those Danish plays. But you're a sound fellow, M. Poirot. Thank you." He took Poirot's hand and gave it a grip which caused the other to wince in anguish. Then he strode to the side-door and passed out into the garden.

"Not every kind of a fool," murmured Poirot, tenderly nursing the injured member. "Only one kind -- the fool in love."

"Mademoiselle Flora went into the garden, I think," he murmured.
