‘That probably settles that hash,’ said the evidently delighted Inspector. He, nevertheless, continued his methodical search down the remainder of the drive and out on the road, but without further result.
He looked at his watch. It was seven o’clock.
‘Two more points and I’m through,’ he said to himself in a satisfied tone.
He turned into the lane and walked slowly down it, scrutinising the roadway as he had done the drive. Three separate times he stopped to examine and measure footmarks, the third occasion being close by the little gate in the hedge.
‘Number one point done. Now for number two,’ he muttered, and returning to the entrance gate stood for a moment looking up and down the road. Choosing the direction of London he walked for a quarter of a mile examining the gateways at either side, particularly those that led into fields. Apparently he did not find what he was in search of, for he retraced his steps to where a cross road led off to the left and continued his investigations along it. No better luck rewarding him, he tried a second cross road with the same result. There being no other cross roads, he returned to the lane and set out again, this time with his back to London. At the third gateway, one leading into a field on the left-hand side of the road, he stopped.
It was an ordinary iron farm gate set in the rather high and thick hedge that bounded the road. The field was in grass and bore the usual building ground notice. Immediately aside the gate was a patch of low and swampy looking ground, and it was a number of fresh wheel marks crossing this patch that had caught the Inspector’s attention.
The gate was not padlocked, and Burnley slipped the bolt back and entered the field. He examined the wheel marks with great care. They turned sharply at right angles on passing through the gate and led for a short distance along the side of the fence, stopping beside a tree which grew in the hedge. The hoof marks of a horse and the prints of a man’s hobnailed boots leading over the same ground also came in for a close scrutiny.
It was a contented looking Burnley that turned out of the field and walked back to St. Malo. He was well satisfied with his night’s work. He had firstly succeeded in getting a lot of information out of Felix, and had further turned the latter into a friend anxious to help in the clearing up of the mystery. And though an unexpected check had arisen in the disappearance of the cask, he felt that with the information he had gained in the last three hours it would not be long before he had his hands on it again.
As he approached the door Felix hailed him.
‘I saw you coming up,’ he said. ‘What luck?’
‘Oh, not so bad, not so bad,’ returned the other. ‘I’m just going back to the city.’
‘But the cask? What about it?’
‘I’ll start some inquiries that may lead to something.’
‘Oh, come now, Inspector, don’t be so infernally close. You might tell me what you’ve got in your mind, for I can see you have something.’
Burnley laughed.
‘Oh, well,’ he said, ‘I don’t mind. I’ll tell you what I found; you see what you make of it.
‘First, I found your coach-house padlock had been forced with a lever. There was nothing of the kind lying about, therefore whatever theory we adopt must account for this lever’s production and disposal. It may quite likely bear marks corresponding to those on the padlock, which evidence might be valuable.
‘I then found that your visitor had arrived at the yard gate with a vehicle and had climbed the wall with the aid of a very peculiar ladder. He had, presumably, opened the gate and, after loading up the cask and drawing his vehicle out on to the drive, had closed the gate, leaving by the same means. There is evidence to show that he lifted the ladder over after him, probably pulling it up by a cord.
‘I have said the ladder was a peculiar one. Here is a sketch of its shape so far as I could learn it. You will see that it is short and wide with the ends shaped differently.
‘I may remind you, in passing, how easy it would have been to load up the cask in spite of its weight. All that was necessary was to back the vehicle under it and lower out the differential pulley, a thing a man could do with one hand.
‘I examined the drive, but could find nothing except at one place where there was a most interesting pair of footmarks. You must really see these for yourself, and if you will stroll down now I will point them out. There is reason to believe they were made by Watty when he was approaching the house with the dray, but I cannot be positive as yet.
‘I then examined the lane and found in three places other footmarks by the same man. Finally, about 200 yards along the main road to the north, I found wheel marks leading into a grass field beside which he had walked.
‘Now, Mr. Felix, put all these things together. You will find them suggestive, but the footmarks on the drive are very nearly conclusive.’
They had by this time reached the marks.
‘Here we are,’ said Burnley. ‘What do you think of these?’
‘I don’t see anything very remarkable about them.’
‘Look again.’
Felix shook his head.
‘See here, Mr. Felix. Stand out here on the gravel and put your right foot in line with this first print. Right. Now take a step forward as if you were walking to the house. Right. Does anything occur to you now?’
‘I can’t say that it does, unless it is that I have taken a very much longer step.’
‘But your step was of normal length.’
‘Well then, conversely, the unknown must have taken a short one.’
‘But did he? Assume it was Watty, as I think it must have been. You were with him and you saw him walking.’
‘Oh, come now, Inspector. How could I tell that? He didn’t normally take very short steps or I should have noticed it, but I couldn’t possibly say that he never took one.’
‘The point is not essential except that it calls attention to a peculiarity in the steps. But you must admit that while possible, it is quite unlikely he would take a step of that length—nineteen inches as against a probable thirty-three—without stumbling or making a false step.’
‘But how do you know he didn’t stumble?’
‘The impression, my dear sir, the impression. A false step or a stumble would have made a blurred mark or shown heavier on one side than the other. This print shows no slip and is evenly marked all over. It was clearly made quite normally.’
‘That seems reasonable, but I don’t see how it matters.’
‘To me it seems exceedingly suggestive though, I agree, not conclusive. But there is a nearly conclusive point, Mr. Felix. Look at those prints again.’
‘They convey nothing to me.’
‘Compare them.’
‘Well, I can only compare the heels and there is not much difference
