“Certainly it is very strange—very strange,” I said. “But if I were you I should not trouble about it. It may be that he has been sent on some special mission abroad.”

“Oh, I shall not worry,” she answered reassuringly. “In a week or two he will return and explain.”

It was upon my lips to tell her the sad news that he would never return, but I stifled the words, and said instead:

“Of course. There is nothing very extraordinary in his omission to give an address. If he is travelling quickly to an uncertain destination, as I have done sometimes, letters are quite out of the question.”

“Yes, I know. But there is yet a stranger fact,” she said. “Last night when we got home Lord Wansford came to supper with some other people, and he told me he had a few hours before seen Jack at Victoria Station talking to a lady who was leaving with a quantity of luggage.”

This new feature was startling, but I saw it was best to scout the idea.

“Old Wansford is rather short-sighted,” I observed. “No doubt he was mistaken. Jack would not wilfully deceive you like that.”

“No. I feel confident he wouldn’t,” she replied, toying with the letter. “My opinion is the same as yours, that he mistook someone else for Jack.”

“No doubt. I’ve been round to his chambers half an hour ago, and seen Mrs Horton. She says he has not been home for three days and that fully bears out his letter.”

“Do you think,” she said hesitatingly a few moments later, “do you think that if I went down to Hounslow I could find out where he has gone? I know Major Tottenham quite well.”
