No other words were spoken for some time, then the lieutenant asked:
"Do you think that an insane person could commit a crime of this kind and have no memory of it in their saner moments?"
"That is a difficult question, Gulston. I do believe that a person in a sudden paroxysm of madness might commit a murder, and upon his recovery be perfectly unconscious of it; but I do not for a moment believe that a madman sufficiently sane to act with the cunning here shown in the mode of obtaining access, by the quiet stealthiness in which the victim was killed whilst in her sleep, and by the attempt to divert suspicion by the abstraction of the trinkets, would lose all memory of his actions afterwards. If Captain Mervyn did this thing, I am sure he would be conscious of it, and I am convinced, as I said, that he is not conscious."
"What will the jury think?" the lieutenant asked after a long pause.
"I think they are sure to return a verdict against him. A coroner's jury are not supposed to go to the bottom of a matter; they are simply to declare whether there is primâ facie evidence connecting any one with a crime; such evidence as is sufficient to justify them in coming to a conclusion that it should at any rate be further examined into. It's a very different thing with a jury at a trial; they have the whole of the evidence that can be obtained before them. They have all the light that can be thrown on the question by the counsel on both sides, and the assistance of the summing-up of the judge, and have then to decide if the guilt of the man is absolutely proven. A coroner's jury is not supposed to go into the whole merits of the case, and their finding means no more than the decision of a magistrate to commit a prisoner for trial. I think the coroner will tell the jury that in this case such evidence as there is before them points to the fact that Captain Mervyn committed this murder, and that it will be their duty to find such a verdict as will ensure the case being further gone into."
"Most of the jury are tenants of the Carnes," Gulston said; "two or three of them I know are, for I met them at the inn when I was over here fishing. They will scarcely like to find against a relation of the family."
"I don't suppose they will," the doctor argued, "but at the same time the coroner will not improbably point out to them that their verdict will simply lead to further investigation of the case, and that even for Captain Mervyn's own sake it is desirable that this should take place, for that the matter could not possibly rest here. Were they to acquit him, I imagine the Chief Constable would at once arrest him and bring him before a magistrate, who, upon hearing a repetition of the evidence given to-day, would have no choice but to commit him for trial."
"I suppose he would do that, anyhow?" Lieutenant Gulston said.
"Not necessarily. I fancy a man can be tried upon the finding of a coroner's jury as well as upon that of a magistrate. Perhaps, however, if the coroner's jury finds against him he may be formally brought up before the magistrates, and a portion of the evidence heard, sufficient to justify them in committing him for trial. See, people are going into the house again. Probably they have thrown the door open, and the jury are going to give their finding. I don't think we need go in."
