'She would have nothing to say to him.'

Poirot looked at him keenly. 'Had she any reason to fear him?'

The young man hesitated. 'There was an incident. You know Zara, the clairvoyant?'

'NO,'

'She is wonderful. You should consult her some time. Valerie and I went to see her last week. She read the cards for us. She spoke to Valerie of trouble - of gathering clouds; then she turned up the last card - the covering card, they call it. It was the king of clubs. She said to Valerie: "Beware. There is a man who holds you in his power. You fear him - you are in great danger through him. You know whom I mean?" Valerie was white to the lips.

She nodded and said: "Yes, yes, I know." Shortly afterwards we left. Zara's last words to Valerie were: "Beware of the king of clubs. Danger threatens you!" I questioned Valerie. She would tell me nothing - assured me that all was well. But now, after last night, I am more sure than ever that in the king of clubs Valerie saw Reedburn, and that he was the man she feared.'

The Prince paused abruptly. 'Now you understand my agitation when I opened the paper this morning. Supposing Valerie, in a fit of madness - oh, it is impossible?

Poirot rose from his seat, and patted the young man kindly on the shoulder. 'Do not distress yourself, I beg of you. Leave it in my hands.'

'You will go to Streatham? I gather she is still there, at Daisy mead - prostrated by the shock.'

'I will go at once.'

'I have arranged matters - through the embassy. You will be allowed access everywhere.'

'Then we will depart - Hastings, you will accompany me? Au revoir, M. le Prince.'

Mon Ddsir was an exceptionally fine villa, thoroughly modern and comfortable. A short carriage-drive led upto it from the road, and beautiful gardens extended behind the house for some acres.

On mentioning Prince Paul's name, the butler who answered the door at once took us to the scene of the tragedy. The library was a magnificent room, running from back to front of the whole building, with a window at either end, one giving on the front carriage-drive, and the other on the garden. It was in the recess of the latter that the body had lain. It had been removed not long before, the police having concluded their examination.

'That is annoying,' I murmured to Poirot. 'Who knows what clues they may have destroyed?'

My little friend smiled. 'Eh - eh! How often must I tell you that dues come from oithin? In the little grey cells of the brain lies the solution of every mystery.'

He turned to the butler. 'I suppose, except for the removal of the body, the room has not been touched?'

'No, sir. It's just as it was when the police came up last night.'

'These curtains, now. I see they pull right across the window-recess.

They are the same in the other window. Were they drawn last night?'

'Yes, sir. I draw them every night.'

'Then Reedburn must have drawn them back himself?'

'I suppose so, sir.'

'Did you know your master expected a visitor last night?'

'He did not say so, sir. But he gave orders he was not to be disturbed after dinner. You see, sir, there is a door leading out of the library on to the terrace at the side of the house. He could have admitted anyone that way.'

'Was he in the habit of doing that?'

The butler coughed discreetly. 'I believe so, sir.'

Poirot strode to the door in question. It was unlocked. He stepped through it on to the terrace which joined the drive on the right; on the left it led up to a red brick wall.

'The fruit garden, sir. There is a door leading into it farther along, but it was always locked at six o'clock.'

Poirot nodded, and re-entered the library, the butler following.

'Did you hear nothing of last night's events?'

'Well, sir, we heard voices in the library, a little before nine.

But that wasn't unusual, especially being a lady's voice. But of course, once we were all in the servants' hall, right the other side, we didn't hear anything at all. And then, about eleven o'clock, the police came.'

'How many voices did you hear?'

'I couldn't say, sir. I only noticed the lady's.'

'Ahl'

'I beg pardon, sir, but Dr Ryan is still in the house, if you would care to see him.'

We jumped at the suggestion, and in a few minutes the doctor, a cheery, middle-aged man, joined us, and gave Poirot all the information he required. Reedburn had been lying near the window, his head by the marble window-seat. There were two wounds, one between the eyes, and the other, the fatal one, on the back of the head.

'He was lying on his back?'

'Yes. There is the mark.' He pointed to a small dark stain on the floor.

'Could not the blow on the back of the head have been caused by his striking the floor?'

'Impossible. Whatever the weapon was, it penetrated some distance into the skull.'

Poirot looked thoughtfully in front of him. In the embrasure of each window was a carved marble seat, the arms being fashioned in the form of a lion's head. A light came into Poirot's eyes.

'Supposing he had fallen backward on this projecting lion's head, and slipped from there to the ground. Would not that cause a wound such as you describe?'

'Yes, it would. But the angle at which he was lying makes that theory impossible. And besides, there could not fail to be traces of blood on the marble of the seat.'

'Unless they were washed away?'

The doctor shrugged his shoulders. 'That is hardly likely. It would be to no one's advantage to give an accident the appearance of murder.'

'Quite so,' acquiesced Poirot. 'Could either of the blows have been struck by a woman, do you think?'

'Oh, quite out of the question, I should say. You are thinking of Mademoiselle Saintclair, I suppose?'

'I think of no one in particular until I am sure,' said Poirot gently.

He turned his attention to the open french window, and the doctor continued:

'It is through here that Mademoiselle Saintclair fled. You can just catch a glimpse of Daisymead between the trees. Of course, there are many houses nearer to the front of the house on the road, but as it happens, Daisymead, though some distance away, is the only house visible this side.' 'Thank you for your amiability, Doctor,' said Poirot. 'Come, Hastings, we will follow the footsteps of Mademoiselle.'

Poirot led the way down through the garden, out through an iron gate, across a short stretch of green and in through the garden gate of Daisymead, which was an unpretentious little house in about half an acre of ground. There was a small flight of steps leading up to a french window. Poirot nodded in their direction.

'That is the way Mademoiselle Saintclair went. For us, who have not her urgency to plead, it will be better to go round to the front door.' A maid admitted us and took us into the drawing-room, then went in search of Mrs Oglander. The room had evidently not been touched since the night before. The ashes were still in the grate, and the bridge-table was still in the centre of the room, with a dummy exposed, and the hands thrown down. The place was somewhat overloaded with gimcrack ornaments, and a good many family portraits of surpassing ugliness adorned the walls.

Poirot gazed at them more leniently than I did, and straightened one or two that were hanging a shade askew. 'La famille, it is a strong tie, is it not? Sentiment, it takes the place of beauty.' I agreed, my eyes being fixed on a family group comprising a gentleman with whiskers, a lady with a high 'front' of hair, a stolid, thick-set boy, and two little girls tied up with a good many unnecessary bows of ribbon. I took this to be the Oglander family in earlier days, and studied it with interest.

The door opened, and a young woman came in. Her dark hair was neatly arranged, and she wore a drab-coloured sportscoat and a tweed skirt.
