Poirot wasted no further time on him. With an amiable little bow — he was always amiable — he left the room and wandered out into the big square hall of Mon Repos. There he stood a minute or two in thought, then, at a slight sound that came to him, cocked his head on one side in the manner of a perky robin, and finally, with noiseless steps, crossed to one of the doors that led out of the hall.
He stood in the doorway, looking into the room; a small room furnished as a library. At a big desk at the further end of it sat a thin, pale young man busily writing. He had a receding chin, and wore a pince-nez.
Poirot watched him for some minutes, and then he broke the silence by giving a completely artificial and theatrical cough.
‘Ahem!’ coughed M. Hercule Poirot.
The young man at the desk stopped writing and turned his head. He did not appear unduly startled, but an expression of perplexity gathered on his face as he eyed Poirot.
The latter came forward with a little bow.
‘I have the honour of speaking to M. Trefusis, yes? Ah! my name is Poirot, Hercule Poirot. You may perhaps have heard of me.’
‘Oh — er — yes, certainly,’ said the young man.
Poirot eyed him attentively.
Owen Trefusis was about thirty-three years of age, and the detective saw at once why nobody was inclined to treat Lady Astwell's accusation seriously. Mr Owen Trefusis was a prim, proper young man, disarmingly meek, the type of man who can be, and is, systematically bullied. One could feel quite sure that he would never display resentment.
‘Lady Astwell sent for you, of course,’ said the secretary. ‘She mentioned that she was going to do so. Is there any way in which I can help you?’
His manner was polite without being effusive. Poirot accepted a chair, and murmured gently:
‘Has Lady Astwell said anything to you of her beliefs and suspicions?’
Owen Trefusis smiled a little.
‘As far as that goes,’ he said, ‘I believe she suspects me. It is absurd, but there it is. She has hardly spoken a civil word to me since Sir Reuben's death, and she shrinks against the wall as I pass by.’
His manner was perfectly natural, and there was more amusement than resentment in his voice. Poirot nodded with an air of engaging frankness.
‘Between ourselves,’ he explained, ‘she said the same thing to me. I did not argue with her — me, I have made it a rule never to argue with very positive ladies. You comprehend, it is a waste of time.’
‘Oh, quite.’
‘I say, yes, Madame — oh, perfectly, Madame —
‘I understand your position perfectly,’ said the secretary. ‘Please regard me as entirely at your service.’
‘
‘Leverson was not at dinner, as you doubtless know,’ said the secretary. ‘He had a serious disagreement with his uncle, and went off to dine at the Golf Club. Sir Reuben was in a very bad temper in consequence.’
‘Not too amiable,
Trefusis laughed.
‘Oh! He was a Tartar! I haven't worked with him for nine years without knowing most of his little ways. He was an extraordinarily difficult man, M. Poirot. He would get into childish fits of rage and abuse anybody who came near him.
‘I was used to it by that time. I got into the habit of paying absolutely no attention to anything he said. He was not bad-hearted really, but he could be most foolish and exasperating in his manner. The great thing was never to answer him back.’
‘Were other people as wise as you were in that respect?’
Trefusis shrugged his shoulders.
‘Lady Astwell enjoyed a good row,’ he said. ‘She was not in the least afraid of Sir Reuben, and she always stood up to him and gave him as good as she got. They always made up afterwards, and Sir Reuben was really devoted to her.’
‘Did they quarrel that last night?’
The secretary looked at him sideways, hesitated a minute, then he said:
‘I believe so; what made you ask?’
‘An idea, that is all.’
‘I don't know, of course,’ explained the secretary, ‘but things looked as though they were working up that way.’
Poirot did not pursue the topic.
‘Who else was at dinner?’
‘Miss Margrave, Mr Victor Astwell, and myself.’
‘And afterwards?’
‘We went into the drawing-room. Sir Reuben did not accompany us. About ten minutes later he came in and hauled me over the coals for some trifling matter about a letter. I went up with him to the Tower room and set the thing straight; then Mr Victor Astwell came in and said he had something he wished to talk to his brother about, so I went downstairs and joined the two ladies.
