‘There is no doubt of it.’

‘That means, I take it, that he was flung out of the boat in such a way that the back of his head struck a rock, killing him before he dropped into the stream?’

‘We do not think so, sir,’ Dr Wilgar answered. ‘In that case he would certainly have swallowed water. Besides, the blow was struck square on with a blunt, smooth-surfaced implement. The skin was not cut as a boulder would have cut it. No, we regret to say so, but the only hypothesis which seems to meet the facts is that Sir William was deliberately murdered.’

‘Good gracious, gentlemen, you don’t say so!’ The chief constable seemed shocked, while the sergeant actually gasped.

‘I am afraid, and Dr Ames agrees with me, that there is no alternative. The blow on the back of the head was struck while Sir William was alive, and it could not have been self inflicted. It would have been sufficient to kill him. The other injuries occurred after death, and it is certain he was not drowned. There is no escape from the conclusion that I have stated. On the contrary, there is every reason to believe a deliberate and carefully thought out crime has been committed. Though it is hardly our province, it seemed to us the whole episode of the boat and the river was merely an attempt to hide the true facts by providing the suggestion of an accident. And I may perhaps be permitted to say that had a less observant and conscientious man than my colleague been called in, the ruse might easily have succeeded.’

‘You amaze me, sir,’ exclaimed Mr Soames. ‘A terrible business! I knew the poor fellow well. I met him in Gateshead before he moved to these parts, and we have been good friends ever since. A sterling, good fellow as ever breathed! I cannot imagine anyone wishing him harm. However, it shows how little we know’… He turned to Inspector Tanner. ‘I presume, Inspector, you came here prepared to take over the case?’

‘Certainly, sir; I was sent for that purpose.’

‘Well, the sooner you get to work the better. And now about the inquest. With the medical evidence there can be but one verdict.’

‘I think, sir,’ observed Tanner, ‘that with your approval it might be wiser to hold that evidence back. It might put some one on his guard, who would otherwise give himself away. I should suggest formal evidence of identification, and an adjournment.’

‘Very possibly you are right, Inspector. What reason would you give for that procedure?’
