Though I did not understand the reason for Poirot’s agitation, I knew him well enough to be sure that he had a reason for it.

We arrived at Rosedew Mansions, Poirot sprang out, paid the driver and hurried into the building. Miss Adams’ flat was on the first floor, as a visiting-card stuck on a board informed us.

Poirot hurried up the stairs, not waiting to summon the lift which was at one of the upper floors.

He knocked and rang. There was a short delay, then the door was opened by a neat middle-aged woman with hair drawn tightly back from her face. Her eyelids were reddened as though with weeping.

‘Miss Adams?’ demanded Poirot eagerly.

The woman looked at him.

‘Haven’t you heard?’

‘Heard? Heard what?’ 

His face had gone deadly pale, and I realized that this, whatever it was, was what he had feared.

The woman continued slowly to shake her head.

‘She’s dead. Passed away in her sleep. It’s terrible.’

Poirot leaned against the doorpost.

‘Too late,’ he murmured.

His agitation was so apparent that the woman looked at him with more attention.

‘Excuse me, sir, but are you a friend of hers? I do not remember seeing you come here before?’

Poirot did not reply to this directly. Instead he said:

‘You have had a doctor? What did he say?’

‘Took an overdose of a sleeping draught. Oh! the pity of it! Such a nice young lady. Nasty dangerous things – these drugs. Veronal he said it was.’

Poirot suddenly stood upright. His manner took on a new authority.

‘I must come in,’ he said.

The woman was clearly doubtful and suspicious.

‘I don’t think–’ she began.

But Poirot meant to have his way. He took probably the only course that would have obtained the desired result.

‘You must let me in,’ he said. ‘I am a detective and I have got to inquire into the circumstances of your mistress’s death.’ 

The woman gasped. She stood aside and we passed into the flat.

From there on Poirot took command of the situation.

‘What I have told you,’ he said authoritatively, ‘is strictly confidential. It must not be repeated. Everyone must continue to think that Miss Adams’ death was accidental. Please give me the name and address of the doctor you summoned.’

‘Dr Heath, 17 Carlisle Street.’

‘And your own name?’

‘Bennett – Alice Bennett.’

‘You were attached to Miss Adams, I can see, Miss Bennett.’

‘Oh! yes, sir. She were a nice young lady. I worked for her last year when she were over here. It wasn’t as though she were one of those actresses. She were a real young lady. Dainty ways she had and liked everything just so.’

Poirot listened with attention and sympathy. He had now no signs of impatience. I realized that to proceed gently was the best way of extracting the information he wanted.

‘It must have been a great shock to you,’ he observed gently.

‘Oh! it was, sir. I took her in her tea – at half-past nine as usual and there she was lying – asleep I thought. And I put the tray down. And I pulled the curtains – one of the rings caught, sir, and I had to jerk it hard. Such a noise it made. I was surprised when I looked round to see she hadn’t woken. And then all of a sudden something seemed to take hold of me. Something not quite natural about the way she lay. And I went to the side of the bed, and I touched her hand. Icy cold it was, sir, and I cried out.’

She stopped, tears coming into her eyes.

‘Yes, yes,’ said Poirot sympathetically. ‘It must have been terrible for you. Did Miss Adams often take stuff to make her sleep?’

‘She’d take something for a headache now and again, sir. Some little tablets in a bottle, but it was some other stuff she took last night, or so the doctor said.’

‘Did anyone come to see her last night? A visitor?’

‘No, sir. She was out yesterday evening, sir.’

‘Did she tell you where she was going?’

‘No, sir. She went out about seven o’clock.’

‘Ah! How was she dressed?’

‘She had on a black dress, sir. A black dress and a black hat.’

Poirot looked at me.

‘Did she wear any jewellery?’

‘Just the string of pearls she always wore, sir.’

‘And gloves – grey gloves?’

‘Yes, sir. Her gloves were grey.’ 

‘Ah! Now describe to me, if you will, what her manner was. Was she gay? Excited? Sad? Nervous?’

‘It seemed to me she was pleased about something, sir. She kept smiling to herself, as though there were some kind of joke on.’

‘What time did she return?’

‘A little after twelve o’clock, sir.’

‘And what was her manner then? The same?’

‘She was terribly tired, sir.’

‘But not upset? Or distressed?’

‘Oh! no, sir. I think she was pleased about something, but just done up, if you know what I mean. She started to ring someone up on the telephone, and then she said she couldn’t bother. She’d do it tomorrow morning.’

‘Ah!’ Poirot’s eyes gleamed with excitement. He leaned forward and spoke in a would-be indifferent voice.

‘Did you hear the name of the person she rang up?’

‘No, sir. She just asked for the number and waited and then the exchange must have said: “I’m trying to get them” as they do, sir, and she said: “All right,” and then suddenly she yawned and said: “Oh! I can’t bother. I’m too tired,” and she put the receiver back and started undressing.’

‘And the number she called? Do you recollect that? Think. It may be important.’ 

‘I’m sorry I can’t say, sir. It was a Victoria number and that’s all I can remember. I wasn’t paying special heed, you see.’

‘Did she have anything to eat or drink before she went to bed?’

‘A glass of hot milk, sir, like she always did.’

‘Who prepared it?’

‘I did, sir.’

‘And nobody came to the flat that evening?’

‘Nobody, sir.’

‘And earlier in the day?’

‘Nobody came that I can remember, sir. Miss Adams was out to lunch and tea. She came in at six o’clock.’

‘When did the milk come? The milk she drank last night?’

‘It was the new milk she had, sir. The afternoon delivery. The boy leaves it outside the door at four o’clock. But, oh! sir, I’m sure there wasn’t nothing wrong with the milk. I had it myself for tea this morning. And the doctor he said positive as she’d taken the nasty stuff herself.’

‘It is possible that I am wrong,’ said Poirot. ‘Yes, it is possible that I am entirely wrong. I will see the doctor. But you see, Miss Adams had enemies. Things are very different in America–’

He hesitated, but the good Alice leapt at the bait.

‘Oh! I know, sir. I’ve read about Chicago and them gunmen and all that. It must be a wicked country and what the police can be about, I can’t think. Not like our policemen.’

Poirot left it thankfully at that, realizing that Alice Bennett’s insular proclivities would save him the trouble of explanations.

His eye fell on a small suitcase – more of an attache case, that was lying on a chair.

‘Did Miss Adams take that with her when she went out last night?’

‘In the morning she took it, sir. She didn’t have it when she came back at tea-time, but she brought it back last thing.’

‘Ah! You permit that I open it?’

Alice Bennett would have permitted anything. Like most canny and suspicious women, once she had overcome her distrust she was child’s play to manipulate. She would have assented to anything Poirot suggested.

The case was not locked, Poirot opened it. I came forward and looked over his shoulder.

‘You see, Hastings, you see?’ he murmured excitedly.

The contents were certainly suggestive.

There was a box of make-up materials, two objects which I recognized as elevators to place in shoes and raise the height an inch or so, there was a pair of grey gloves and, folded in tissue paper, an exquisitely-made wig of golden hair, the exact shade of gold of Jane Wilkinson’s and dressed like hers with a centre parting and curls in the back of the neck.
