When the body had been laid on the bed in Sir William’s room, and the little excitement caused by the arrival had subsided, the sergeant approached Austin Ponson.

‘Beg pardon, Mr Ponson,’ he said. ‘I’m very sorry, but I’ll have to make a report about this, and I’m bound to ask a few questions. I hope, sir, you won’t mind?’

‘Of course not, sergeant. I understand you must do your duty.’

‘Thank you, sir. May I ask then if you can explain how this accident occurred?’

‘No more than you can, sergeant. I only know that Innes, Sir William’s valet, came to my house when I was dressing this morning, to know if Sir William was with me. He said he had gone out after dinner last night without leaving any message, and they didn’t know where he was. I came back with Innes, and they had just then learnt that the boat was missing. We thought perhaps my father had rowed across the river to see Dr Graham, and I sent round to inquire, but when we learnt he hadn’t been there we began to fear the worst. We therefore went down the river to see if we could find anything.’

‘And when, sir, did you see him last?’

‘On Sunday evening—three days ago. I dined here, and left about ten or later.’

‘And was he in his usual health and spirits then?’

‘Yes, I noticed nothing out of the common.’

‘And he said nothing then, or indeed at any time, that would explain the matter?’
