fifth man had crossed the paling almost at the same place as the others—it was the obviously suitable place—but instead of turning up towards the house, his steps led direct to the boathouse! Another line of the same steps led back from the boathouse to the fence—in neither case continuously, but here and there, where the grass was thin. And at two points along these tracks the Inspector gave a chuckle of satisfaction. At one there was a perfect impression of part of the right sole, and at another of the remainder and the heel. Tanner decided he must take plaster casts of these prints before they became blurred.
Passing the boathouse—he felt that marks in it, if any, would keep—he continued his careful search of the bank above flood level. Very painstaking and thorough he was as he gradually worked his way up, but no further traces could he find. At last after a good hour’s work he reached the Old Ferry. Here the track approaching the ruined pier was hard; and he recognised that, shut in as it was by trees, it would have made an ideal place for disposing of the body. He thought he need hardly expect traces above this, but, as he wished to cross the river, and he could do so no nearer than the London road bridge at Halford, he continued along the bank, still searching. Then, reaching the bridge, he crossed and worked in the same way down the left bank till he reached the other bridge at the Cranshaw Falls. When the work was completed, he felt positive the body could only have been set adrift at either the boathouse or the Old Ferry.
It was now eleven o’clock, and he had been at it for over five hours. Taking the bicycle, he rode back into Halford, where he had a hurried meal. Then he left again to attend the inquest at Luce Manor.
A long, narrow room, with oak-panelled walls, and three deep windows, had been set aside for the occasion. Round the table, which ran down the centre, sat the jury, looking self-conscious and important. At the head was the Coroner, and near him, but a little back from the table, were Austin and Cosgrove Ponson, Dr Ames, the butler, valet, boatman, sergeant, and a few other persons. As Tanner entered and slipped quietly to a seat, the Coroner was just rising to open the proceedings.
He made a brief speech deploring the unhappy event which had robbed their neighbourhood of so worthy and so useful a man as Sir William, and expressing on his own behalf and that of those present the sympathy which they felt for the surviving members of the family. Then he lamented the fact that the law required an inquest, and promised that on his part at least the proceedings should be conducted so as to give the least possible amount of annoyance and pain. Partly on that account, and partly because the authorities for technical reasons required some information which there had not as yet been time to obtain, he did not propose to complete the inquest that day, but after formal evidence of identification had been taken he would adjourn the proceedings to a more convenient date.
The speech was cleverly worded. While it stated nothing explicitly, its whole suggestion was that as every one knew an accident had happened, further inquiry must be mere waste of time. He touched but slightly on the adjournment, proceeding at once to call the roll and swear in the jury.
While he was speaking Tanner ran his sharp eyes over the faces of those present, memorising their features, and noting their demeanour. There sat Parkes, the butler, solemn and ponderous, surveying the scene with grave and decorous interest. Innes, sharp-eyed and alert, seemed to be watching the proceedings with an eye for flaws in the Coroner’s law. Smith, the gardener-boatman, somewhat overawed with his surroundings, was evidently there, a plain man, to tell a plain man’s tale. After registering a mental picture of each, Tanner’s gaze passed on, but when it reached Austin Ponson it halted and remained steady.
The son and nephew were seated together. There was a considerable similarity in their appearance. Of middle height, both had blue eyes, clear complexions, and clean-shaven chins. Their features were not unlike, but Austin was stouter, and seemed younger, and more easy going. Cosgrove looked as if he had lived hard. He was thin, and lines radiated from the corners of his eyes while the hair near his temples showed slightly grey. He had the indefinable stamp of a society man, which Austin lacked. But both were well looking enough, and would have passed unnoticed among any crowd of well-dressed Englishmen of the upper classes.
But it was not on these points of superficial resemblance that Tanner’s gaze rested. He was a reader, so far as he was able, of hearts. And it was the expressions of the cousins which had specially attracted his attention.
That both were shocked and upset by the tragedy there could be no doubt. But, while this seemed the sum total of Cosgrove’s emotion, the detective’s keen eye recognised something more in Austin’s face and bearing. He was anxious—unquestionably anxious—and he was trying to hide it. And when the Coroner mentioned the adjournment he started, and a look of undoubted fear showed for a moment in his eyes. Inspector Tanner’s interest was keenly aroused. That Austin knew something he felt sure, and he decided his first business must be to learn what it was.
Accordingly, when the body had been viewed and formally identified, and the proceedings had come to an end, he sought out his victim, and quietly introduced himself.
‘I am exceedingly sorry, Mr Ponson,’ he said politely, ‘to intrude myself upon you at such a moment, but I have been sent here by Scotland Yard to make certain inquiries into this unhappy occurrence, and I have no option but to carry out my instructions. Could you spare me a few moments?’
Austin’s face paled as the other made his occupation known, and again the look of fear showed in his eyes. But he answered readily enough:
‘Certainly, Inspector. I am at your service. Come in here; we shall not be disturbed.’
He led the way into a small study or office on the left of the hall, plainly furnished in mahogany, with dark red leather upholstering. Drawing forward two arm-chairs he motioned his visitor to a seat.
‘I should feel greatly obliged, sir,’ began Tanner, as he accepted a cigarette from the case the other held out, ‘if you would tell me all you can about this unhappy affair. I have practically only arrived, and I have not heard the details.’
‘There’s not much I can tell you, I’m afraid,’ Austin answered, and then he repeated almost word for word the statement he had made to the sergeant. He spoke calmly, but the Inspector could see that he was ill at ease.
‘It seemed to my people,’ went on Tanner, ‘that a good deal hinged on the motive Sir William had for taking out the boat. You cannot form any theory about that?’
‘None whatever. It was the last thing I should have expected him to do.’
‘There is no one whom he might have wished to visit?’
‘The butler suggested that,’ and Austin mentioned Dr Graham. ‘But,’ he ended up, ‘we could find nothing to bear out that theory.’
‘Can you tell me if Sir William had anything on his mind recently?’
Austin hesitated and moved uneasily.
‘No,’ he said, ‘not to my knowledge.’ But his voice changed, and the Inspector felt he was not speaking the truth.
‘When did you see him last, Mr Ponson?’
‘On Sunday. I dined here and spent the evening.’
‘And you noticed nothing unusual in his manner then?’
‘Nothing.’
‘You will be wondering what is the point of all these questions. I am sorry to tell you, Mr Ponson, that my superiors have got an exceedingly unpleasant suspicion into their minds. I hardly like to mention it to you.’
The Inspector paused, watching the other keenly. He was evidently on tenterhooks. Seemingly unable to remain quiet, he threw his cigarette away, and then with quick, jerky movements lit another. But he controlled himself and spoke calmly.
‘Yes? What do they think?’
‘They are not satisfied,’ went on Tanner, slowly watching all the time the effect of his words, ‘that the affair was an accident at all.’
