‘The parlourmaid is leaving.’

‘When?’

‘She gave notice yesterday, I believe.’

‘To you?’

‘Oh, no. I have nothing to do with the servants. Miss Russell attends to the household matters.’

The inspector remained lost in thought for a minute or two. Then he nodded his head and remarked,

‘I think I’d better have a word with Miss Russell, and I’ll see the girl Dale as well.’

Poirot and I accompanied him to the housekeeper’s room. Miss Russell received us with her usual sang-froid. Elsie Dale had been at Fernly five months. A nice girl, quick at her duties, and most respectable. good references. The last girl in the world to take anything not belonging to her.

What about the parlourmaid?

‘She, too, was a most superior girl. Very quiet and ladylike. An excellent worker.’

‘Then why is she leaving?’ asked the inspector.

Miss Russell pursed up her lips. ‘It was none of my doing. I understand Mr Ackroyd found fault with her yesterday afternoon. It was her duty to do the study, and she disarranged some of the papers on his desk, I believe. he was very annoyed about it, and she gave notice. At least, that is what I understood from her, but perhaps you’d like to see her yourselves?’

The inspector assented. I had already noticed the girl when she was waiting on us at lunch. A tall girl, with a lot of brown hair rolled tightly away at the back of her neck, and very steady grey eyes. She came in answer to the housekeeper’s summons, and stood very straight with those same grey eyes fixed on us.

‘You are Ursula Bourne?’ asked the inspector.

‘Yes, sir.’

‘I understand you are leaving?’

‘Yes, sir.’

‘Why is that?’

‘I disarranged some papers on Mr Ackroyd’s desk. He was very angry about it, and I said I had better leave. he told me to go as soon as possible.’

‘Were you in Mr Ackroyd’s bedroom at all last night? Tidying up or anything?’

‘No, sir. That is Elsie’s work. I never went near that part of the house.’

‘I must tell you, my girl, that a large sum of money is missing from Mr Ackroyd’s room.’

At last I saw her roused. A wave of colour swept over her face.

‘I know nothing about any money. If you think I took it, and that that is why Mr Ackroyd dismissed me, you are wrong.’

‘I’m not accusing you of taking it, my girl,’ said the inspector. ‘Don’t flare up so.’

The girl looked at him coldly.

‘You can search my things if you like,’ she said disdainfully. ‘But you won’t find anything.’

Poirot suddenly interposed.

‘It was yesterday afternoon that Mr Ackroyd dismissed you – or you dismissed yourself, was it not?’ he asked.

The girl nodded.

‘How long did the interview last?’

‘The interview?’

‘Yes, the interview between you and Mr Ackroyd in the study?’

‘I–I don’t know.’

‘Twenty minutes? Half an hour?’

‘Something like that.’

‘Not longer?’

‘Not longer than half an hour, certainly.’

‘Thank you, mademoiselle.’

I looked curiously at him. He was rearranging a few objects on the table, setting them straight with precise fingers. His eyes were shining.

‘That’ll do,’ said the inspector.

Ursula Bourne disappeared. The inspector turned to Miss Russell.

‘How long has she been here? have you got a copy of the reference you had with her?’

Without answering the first question, Miss Russell moved to an adjacent bureau, opened one of the drawers, and took out a handful of letters clipped together with a patent fastener. She selected one and handed it to the inspector.

‘H’m,’ said he. ‘reads all right. Mrs Richard Folliott, Marby grange, Marby. Who’s this woman?’

‘Quite good country people,’ said Miss Russell.

‘Well,’ said the inspector, handing it back, ‘let’s have a look at the other one, Elsie Dale.’

Elsie Dale was a big fair girl, with a pleasant but slightly stupid face. She answered our questions readily enough, and showed much distress and concern at the loss of the money.

‘I don’t think there’s anything wrong with her,’ observed the inspector, after he had dismissed her. ‘What about Parker?’

Miss Russell pursed her lips together and made no reply.

‘I’ve a feeling there’s something wrong about that man,’ the inspector continued thoughtfully. ‘The trouble is that I don’t quite see when he got his opportunity. he’d be busy with his duties immediately after dinner, and he’d got a pretty good alibi all through the evening. I know, for I’ve been devoting particular attention to it. Well, thank you very much, Miss russell. We’ll leave things as they are for the present. It’s highly probable Mr Ackroyd paid that money away himself.’

The housekeeper bade us a dry good afternoon, and we took our leave.

I left the house with Poirot.

‘I wonder,’ I said, breaking the silence, ‘what the papers the girl disarranged could have been for Ackroyd to have got into such a state about them? I wonder if there is any clue there to the mystery.’

‘The secretary said there were no papers of particular importance on the desk,’ said Poirot quietly.

‘Yes, but-’ I paused.

‘It strikes you as odd that Ackroyd should have flown into a rage about so trivial a matter?’

‘Yes, it does rather.’

‘But was it a trivial matter?’

‘Of course,’ I admitted, ‘we don’t know what those papers may have been. But Raymond certainly said-’

‘Leave M. Raymond out of it for a minute. What did you think of that girl?’

‘Which girl? The parlourmaid?’

‘Yes, the parlourmaid. Ursula Bourne.’

‘She seemed a nice girl,’ I said hesitatingly.

Poirot repeated my words, but whereas I had laid a slight stress on the fourth word, he put it on the second.

‘She seemed a nice girl – yes.’

Then, after a minute’s silence, he took something from his pocket and handed it to me.

‘See, my friend, I will show you something. Look there.’

The paper he had handed me was that compiled by the inspector and given by him to Poirot that morning. following the pointing finger, I saw a small cross marked in pencil opposite the name Ursula Bourne.

‘You may not have noticed it at the time, my good friend, but there was one person on this list whose alibi had no kind of confirmation. Ursula Bourne.’

‘You don’t think-?’

‘Dr Sheppard, I dare to think anything. Ursula Bourne may have killed Mr Ackroyd, but I confess I can see no motive for her doing so. Can you?’

He looked at me very hard – so hard that I felt uncomfortable.

‘Can you?’ he repeated.

‘No motive whatsoever,’ I said firmly.

His gaze relaxed. He frowned and murmured to himself:

‘Since the blackmailer was a man, it follows that she cannot be the blackmailer, then-’ I coughed.

‘As far as that goes-’ I began doubtfully.

He spun round on me.

‘What? What are you going to say?’

‘Nothing, Nothing. Only that, strictly speaking, Mrs Ferrars in her letter mentioned a person – she didn’t actually specify a man. But we took it for granted, Ackroyd and I, that it was a man.’

Poirot did not seem to be listening to me. He was muttering to himself again.

‘But then it is possible after all – yes, certainly it is possible – but then – ah! I must rearrange my ideas. Method, order, never have I needed them more. everything must fit in – in its appointed place – otherwise I am on the wrong track.’ He broke off, and whirled round upon me again. ‘Where is Marby?’
