Yet it was not a night spent in thought, but rather in intercepting and in casting out the kind of thoughts that chased each other through the novelist’s brain.  His imagination had him by the forelock once more, but this time he was resisting with all his might.  It meant resistance to the strongest attribute that he possessed.  The man’s mind was now a picture-gallery and now a stage.  He thought in pictures and he saw in scenes.  It was no fault of Langholm’s, any more than it was a merit.  Imagination was the predominant force of his intellect, as in others is the power of reasoning, or the gift of languages, or the mastery of figures.  Langholm could no more help it than he could change the color of his eyes, but to-night he did his best.  He had mistaken invention for discovery once already.  He was grimly determined not to let it happen twice.

To suspect Steel because he chanced to have been in the neighborhood of Chelsea on the night of the murder, and absent from his hotel about the hour of its committal, was not less absurd than his first suspicion of the man who could be proved to have been lying between life and death at the time.  There had been something to connect the dead man with Severino.  There was nothing within Langholm’s knowledge to connect him with Steel.  Yet Steel was the most mysterious person that he had ever met with outside the pages of his own novels.  No one knew where he had made his money.  He might well have made it in Australia; they might have known each other out there.  Langholm suddenly remembered the Australian swagman whom he had seen “knocking down his check” at a wayside inn within a few miles of Normanthorpe, and Steel’s gratuitously explicit statement that neither he nor his wife had ever been in Australia in their lives.  There was one lie at least, then why not two?  Yet, the proven lie might have been told by Steel simply to anticipate and allay any possible suspicion of his wife’s identity.  That was at least conceivable.  And this time Langholm sought the conceivable explanation more sedulously than the suspicious circumstance.

He had been far too precipitate in all that he had done hitherto, from the Monday morning up to this Wednesday night.  His departure on the Monday had been in itself premature.  He had come away without seeing the Steels again, whereas he should have had an exhaustive interview with one or both of them before embarking upon his task.  But Steel’s half-hostile and half-scornful attitude was more than Langholm could trust his temper to endure, and he had despaired of seeing Mrs. Steel alone.  There were innumerable points upon which she could have supplied him with valuable information.  He had hoped to obtain what he wanted from the fuller reports of the trial; but that investigation had been conducted upon the supposition that his wife, and no other, had caused the death of Alexander Minchin.  No business friend of the deceased had been included among the witnesses, and the very least had been made of his financial difficulties, which had formed no part of the case for the Crown.
