“A man of science, Mr. Blackmore,” he said, “expects nothing. He collects facts and keeps an open mind. As to me, I am a mere legal Autolycus, a snapper-up of unconsidered trifles of evidence. When I have accumulated a few facts, I arrange them, compare them and think about them. Sometimes the comparison yields new matter and sometimes it doesn’t; but in any case, believe me, it is a capital error to decide beforehand what data are to be sought for.”

“Yes, I suppose that is so,” said Stephen; “though, to me, it almost looks as if Mr. Marchmont was right; that there is nothing to investigate.”

“You should have thought of that before you consulted me,” laughed Thorndyke. “As it is, I am engaged to look into the case and I shall do so; and, as I have said, I shall keep an open mind until I have all the facts in my possession.”
