“I answered that I had explained them in my letter to his wife.

“ ‘Yes, yes, you said that you had known Godfrey in Africa. We have, of course, only your word for that.’

“ ‘I have his letters to me in my pocket.’

“ ‘Kindly let me see them.’

“He glanced at the two which I handed him, and then he tossed them back.

“ ‘Well, what then?’ he asked.

“ ‘I was fond of your son Godfrey, sir. Many ties and memories united us. Is it not natural that I should wonder at his sudden silence and should wish to know what has become of him?’

“ ‘I have some recollections, sir, that I had already corresponded with you and had told you what had become of him. He has gone upon a voyage round the world. His health was in a poor way after his African experiences, and both his mother and I were of opinion that complete rest and change were needed. Kindly pass that explanation on to any other friends who may be interested in the matter.’

“ ‘Certainly,’ I answered. ‘But perhaps you would have the goodness to let me have the name of the steamer and of the line by which he sailed, together with the date. I have no doubt that I should be able to get a letter through to him.’

“My request seemed both to puzzle and to irritate my host. His great eyebrows came down over his eyes, and he tapped his fingers impatiently on the table. He looked up at last with the expression of one who has seen his adversary make a dangerous move at chess, and has decided how to meet it.

“ ‘Many people, Mr. Dodd,’ said he, ‘would take offence at your infernal pertinacity and would think that this insistence had reached the point of damned impertinence.’

“ ‘You must put it down, sir, to my real love for your son.’

“ ‘Exactly. I have already made every allowance upon that score. I must ask you, however, to drop these inquiries. Every family has its own inner knowledge and its own motives, which cannot always be made clear to outsiders, however well-intentioned. My wife is anxious to hear something of Godfrey’s past which you are in a position to tell her, but I would ask you to let the present and the future alone. Such inquiries serve no useful purpose, sir, and place us in a delicate and difficult position.’

“So I came to a dead end, Mr. Holmes. There was no getting past it. I could only pretend to accept the situation and register a vow inwardly that I would never rest until my friend’s fate had been cleared up. It was a dull evening. We dined quietly, the three of us, in a gloomy, faded old room. The lady questioned me eagerly about her son, but the old man seemed morose and depressed. I was so bored by the whole proceeding that I made an excuse as soon as I decently could and retired to my bedroom. It was a large, bare room on the ground floor, as gloomy as the rest of the house, but after a year of sleeping upon the veldt, Mr. Holmes, one is not too particular about one’s quarters. I opened the curtains and looked out into the garden, remarking that it was a fine night with a bright half-moon. Then I sat down by the roaring fire with the lamp on a table beside me, and endeavoured to distract my mind with a novel. I was interrupted, however, by Ralph, the old butler, who came in with a fresh supply of coals.
