Cranston entered upon his work at once and with zeal. His first visit was to Millbank and the Parlin house, where, as has been said, he searched from top to bottom. He plied Mrs. Parlin with questions that finally got from her the story of the package of papers, which she was not conscious of having seen until his questions stirred her memory to recall a picture of the room the night before the murder. Then came out clearly and distinctly the package of papers lying on the desk. It was, however, equally certain that they were gone, and of this he was able to satisfy himself without letting Mrs. Parlin understand that he attached any importance to the matter. The task was left him of ascertaining whether Trafford or McManus had them. The episode of the writing-pad convinced him that Trafford was the man, and that the pad was simply a cover to the removal of the papers that were resting on it. It was this that caused the annoyance to which Mrs. Parlin had referred.

He went over the ground under the consciousness that eyes at least as capable of seeing as his own had preceded him, and that there was little chance that anything had escaped them and less chance that, if there had, he would be able to discover it. It irritated him that men who wanted real service should call him in at so late an hour, and then seem to take it for granted that they had done all that was necessary.

“Oldbeg has been here a good many years,” he said carelessly to Mrs. Parlin, who insisted on attending him in his investigation.

“You have always found him faithful?”

“There has been nothing particular to complain of. He’s been steady and has worked hard and usually shown good temper.”

“Usually,” Cranston repeated. “Then sometimes he hasn’t.”

“He has his off-days, the same as the rest of us; days when things don’t go right and he gets surly. But those spells pass quickly and he’s always sorry for them, seemingly. There aren’t any of us smooth-feathered all the time.”

“When did he have one of these ‘off-days,’ as you call them, last?” The tone was careless, as if Cranston did not attach much importance to the enquiry, and yet made it, as in duty bound.

“On the Sunday before——”
