The question was not, apparently, easy to solve, for Mr. Butterby was a long while pondering it.

"He couldn't get back into the house up through the windows or down through the chimneys; not in anyway but through the door. And the chances were that he might have been seen going in and coming out. No: don't think he went back to harm Mr. Ollivera. Rather inclined to say his announced intention of starting by the five o'clock train to Birmingham was a blind: he meant to go by the one at eight t'other way, and went back to wait for it, afeared of hanging about the station itself or loitering in the streets. It don't quite wash, neither, that; chances were he might have been seen coming back," debated Mr. Butterby.

"Wonder if he has anything to do with that little affair that has just turned up in Birmingham?" resumed the speaker, deviating to another thought. "Young man's wanted for that, George Winter: might have been this very selfsame Godfrey Pitman; and of course might not. Let's get on.

"It don't stand to reason that he'd come in any such way into a town and stop a whole week at the top of a house for the purpose of harming Mr. Ollivera. Why 'twas not till the Tuesday after Pitman was in, that the Joneses got the barrister's letter saying he was coming and would occupy his old rooms if they were vacant. No," decided Mr. Butterby; "Pitman was in trouble on his own score, and his mysterious movements had reference to that: as I'm inclined to think."

One prominent quality in Mr. Butterby was pertinacity. Let him take up an idea of his own accord, however faint, and it took a vast deal to get it out of him. An obstinate man was he in his self-conceit. Anybody who knew Mr. Butterby well, and could have seen his thoughts as in a glass, might have known he would be slow to take up the doubts against Godfrey Pitman, because he had already them up against another.

"I don't like it," he presently resumed. "Look at it in the best light, she knows something of the matter; more than she likes to be questioned about. Put the case, Jonas Butterby. Here's a sober, sensible, steady young woman, superior to half the women going, thinking only of her regular duties, nothing to conceal, open and cheerful as the day. That's how she was till this happened. And now? Goes home on the Monday night at nigh eleven o'clock (not to speak yet of what passed up to that hour), sits over the parlour-fire after other folks had went to bed, 'thinking,' as she puts it. Goes up later; can't sleep; drops asleep towards morning, and dreams that Mr. Ollivera's dead. Gets flurried at inquest (I saw it, though others mightn't); tramps to see him buried, stands on the fresh grave, and tells the public he did not commit suicide. How does she know he didn't? Come. Mrs. Jones is ten times sharper-sighted, and she has no doubt. Says, next, to her sister in confidence (and Dicky repeats it to me as a choice bit of gossip) that she's haunted by Ollivera's spirit.

"I don't like that," pursued Mr. Butterby, after a revolving pause. "When folks are haunted by dead men's spirits--leastways, fancy they are--it bodes a conscience not at rest in regard to the dead. To-night her face was pale and red by turns; her fingers shook so they had to clutch her work; she won't talk of it; she left the room to avoid me. And," continued Mr. Butterby, "she was the only one, so far as can be yet seen, that was for any length of time in the house between half-past seven and eight on Monday evening. A quarter of an hour finding a sleeve-pattern!

"I don't say it was her; I've not got as far as that yet, by a long way. I don't yet say it was not as the jury brought it in. But she was in the house for that quarter of an hour, unaccounting for her stay in accordance with any probability; and I'm inclined to think that Godfrey Pitman must have been out of it before the harm was done. Nevertheless, appearances is deceitful, deductions sometimes wrong, and while I keep a sharp eye on the lady, I shall look you up, Mr. Godfrey Pitman."

One drawback against the "looking up" was--and Mr. Butterby felt slightly conscious of it as he rose from his seat before the fire--that he had never seen Godfrey Pitman in his life; and did not know whence he came or whither he might have gone.
