"I wonder what you call luck," said Ned. "Seems to me you were up against it all the time! You've told me how you caught Rattar lying at the start. Well, that was pretty smart of you to begin with. Then, what next? How did things come?" "Well," said Carrington, "I picked up a little something on my first visit to Keldale. From Bisset's description I gathered that the body must have been dragged along the floor and left near the door. Why? Obviously as a blind. Adding that fact to the unfastened window, the broken table, the mud on the floor, and the hearth brush, the odds seemed heavy on entry by the window. I also found that the middle blind had been out of order that night and that it _might_ have been quite possible for any one outside to have seen Sir Reginald sitting in the room and known he was alone there. Again, it seemed long odds on his having recognised the man outside and opened the window himself, which, again, pointed to the man being some one he knew quite well and never suspected mischief from." "Those were always my own ideas, except that I felt bamboozled where you felt clear--which shows the difference between our brains!" Carrington laughed and shook his head. "I wish I could think so! No, no, it's merely a case of every man to his own trade. And as a matter of fact I was left just as bamboozled as you were. For who could this mysterious man be? Of the people inside the house, I had struck out Miss Farmond, Bisset, Lady Cromarty, and all the female servants. Only Sir Malcolm was left. I wired for him to come up and was able to score him out too. I also visited you and scored you out. So there I was--with no conceivable criminal!" "But you'd already begun to suspect Rattar, hadn't you?" "I knew he had lied about engaging me; I discovered from Lady Cromarty that he had told her of Sir Malcolm's engagement to Miss Farmond--and I suspected he had started her suspicions of them; and I saw that he was set on that theory, in spite of the fact that it was palpably improbable if one actually knew the people. Of course if one didn't, it was plausible enough. When I first came down here it seemed to me a very likely theory and I was prepared to find a guilty couple, but when I met Miss Farmond and told her suddenly that Sir Malcolm was arrested, and she gazed blankly at me and asked 'What for?' well, I simply ran my pencil, so to speak, through her name and there was an end of her! The same with Sir Malcolm when I met him. And yet here was the family lawyer, who knew them both perfectly, so convinced of their guilt that he was obviously stifling investigation in any other direction. And on top of all that, all my natural instincts and intuitions told me that the man was a bad hat." "But didn't all that make you suspect him?"
