Poirot had looked up at the staircase in passing, and shook his head in a dissatisfied manner.
'It is to me incredible that the servants heard nothing. The creaking of that staircase, with three people descending it, would awaken the dead!'
'It was the middle of the night, remember. They were sound asleep by then.'
But Poirot continued to shake his head as though not fully accepting the explanation. On the sweep of the drive he paused, looking up at the house.
'What moved them in the first place to try if the front door were open? It was a most unlikely thing that it should be. It was far more probable that they should at once try to force a window.'
'But all the windows on the ground floor are barred with iron shutters,' objected the commissary.
Poirot pointed to a window on the first floor,
'That is the window of the bedroom we have just come from, is it not? And see-there is a tree by which it would be the easiest thing in the world to mount.'
'Possibly,' admitted the other. 'But they could not have done so without leaving footprints in the flowerbed.'
I saw the justice of his words. There were two large oval flowerbeds planted with scarlet geraniums, one each side of the steps leading up to the front door. The tree in question had its roots actually at the back of the bed itself, and it would have been impossible to reach it without stepping on the bed.
'You see,' continued the commissary, 'owing to the dry weather no prints would show on the drive or paths; but, on the soft mould of the flowerbed, it would have been a very different affair.'
Poirot went close to the bed and studied it attentively. As Bex had said, the mould was perfectly smooth. There was not an indentation on it anywhere.
Poirot nodded, as though convinced, and we turned away; but he suddenly darted off and began examining the other flowerbed.
'Monsieur Bex!' he called. 'See here. Here are plenty of traces for you.'
The commissary joined him-and smiled.
'My dear Monsieur Poirot, those are without doubt the footprints of the gardener's large hobnailed boots. In any case, it would have no importance, since this side we have no tree, and consequently no means of gaining access to the upper storey.'
'True,' said Poirot, evidently crestfallen. 'So you think these footprints are of no importance?'
'Not the least in the world.'
Then to my utter astonishment, Poirot pronounced these words: 'I do not agree with you. I have a little idea that these footprints are the most important things we have seen yet.'
M. Bex said nothing, merely shrugged his shoulders. He was far too courteous to utter his real opinion.
'Shall we proceed?' he asked, instead.
'Certainly. I can investigate this matter of the footprints later,' said Poirot cheerfully.
Instead of following the drive down to the gate, M. Bex turned up a path that branched off at right angles. It led, up a slight incline, round to the right of the house, and was bordered on either side by a kind of shrubbery. Suddenly it emerged into a little clearing from which one obtained a view of the sea. A seat had been placed here, and not far from it was a rather ramshackle shed. A few steps farther on, a neat line of small bushes marked the boundary of the villa grounds. M. Bex pushed his way through these, and we found ourselves on a wide stretch of open downs. I looked round, and saw something that filled me with astonishment: 'Why, this is a Golf Course,' I cried.
Bex nodded.
'The links are not completed yet,' he explained. 'It is hoped to be able to open them some time next month. It was some of the men working on them who discovered the body early this morning.'
I gave a gasp. A little to my left, where for the moment I had overlooked it, was a long narrow pit and by its face downwards, was the body of a man! For a moment, my heart gave a terrible leap, and I had a wild fancy that the tragedy had been duplicated. But the commissary dispelled my illusion by moving forward with a sharp exclamation of annoyance: 'What have my police been about? They had strict orders to allow no one near the place without proper credentials!'
The man on the ground turned his head over his shoulder.
'But I have proper credentials.' he remarked and rose slowly to his feet.
'My dear Monsieur Giraud,' cried the commissary. 'I had no idea that you had arrived, even. The examining magistrate has been awaiting you with the utmost impatience.'
As he spoke, I was scanning the newcomer with the keenest curiosity. The famous detective from the Paris Sûreté was familiar to me by name and I was extremely interested to see him in the flesh. He was very tall, perhaps about thirty years of age, with auburn hair and moustache, and a military carriage. There was a trace of arrogance in his manner which showed that he was fully alive to his own importance.
Bex introduced us, presenting Poirot as a colleague. A flicker of interest came into the detective's eye.
'I know you by name, Monsieur Poirot,' he said. 'You cut quite a figure in the old days, didn't you? But methods are very different now.'
'Crimes, though, are very much the same,' remarked Poirot gently.
I saw at once that Giraud was prepared to be hostile. He resented the other being associated with him, and I felt that if he came across any clue of importance he would be more than likely to keep it to himself.
'The examining magistrate-' began Bex again.
But Giraud interrupted rudely: 'A fig for the examining magistrate! The light is the important thing. For all practical purposes it will be gone in another half hour or so. I know all about the case, and the people at the house will do very well until tomorrow; but, if we're going to find a clue to the murderers, here is the spot we shall find it. Is it your police who have been trampling all over the place? I thought they knew better nowadays.'
'Assuredly they do. The marks you complain of were made by the workmen who discovered the body.'
The other grunted disgustedly.
'I can see the tracks where the three of them came through the hedge-but they were cunning. You can just recognize the centre footmarks as those of Monsieur Renauld, but those on either side have been carefully obliterated. Not that there would really be much to see anyway on this hard ground, but they weren't taking any chances.'
'The external sign,' said Poirot. 'That is what you seek, eh?'
The other detective stared.
'Of course.'
A very faint smile came to Poirot's lips. He seemed about to speak, but checked himself. He bent down to where a spade was lying.
'That's what the grave was dug with, right enough,' said Giraud. 'But you'll get nothing from it. It was Renauld's own spade, and the man who used it wore gloves. Here they are.' He gesticulated with his foot to where two soil-stained gloves were lying. 'And they're Renauld's too-or at least his gardener's. I tell you, the men who planned out this crime were taking no chances. The man was stabbed with his own dagger, and would have been buried with his own spade. They counted on leaving no traces! But I'll beat them. There's always something! And I mean to find it.'
But Poirot was now apparently 'interested in something else, a short, discoloured piece of lead-piping which lay beside the spade. He touched it delicately with his finger.
'And does this, too, belong to the murdered man?' he asked, and I thought I detected a subtle flavour of irony in the question.
Giraud shrugged his shoulders to indicate that he neither knew nor cared.
'May have been lying around here for weeks. Anyway, it doesn't interest me.'
'I, on the contrary, find it very interesting,' said Poirot suavely.
I guessed that he was merely bent on annoying the Paris detective and if so, he succeeded. The other turned away rudely remarking that he had no time to waste, and bending down he resumed his minute search of the ground.
Meanwhile, Poirot, as though struck by a sudden idea, stepped back over the boundary, and tried the door of the little shed.
'That's locked,' said Giraud over his shoulder. 'But it's only a place where the gardener keeps his rubbish. The
