Coroner Scofield was a man of tact. “It is entirely natural, Miss Stuart,” he said, “that this thought should overcome you. But we must realize the fact that the theory of a professional burglar is practically untenable, because nothing was stolen. A burglar’s motive could be only robbery, and this did not take place. Nor can we think that a burglar was frightened away, before he could appropriate the jewels. For, after giving the poison, and before the blow was given, sufficient time elapsed for a successful getaway to be made. Nor would the burglar have been at pains to cover up his poisoning work, for having achieved his end, he would have secured his booty and made escape. So, it is evident that the motive, not being robbery, is as yet unknown, and may be obscure and complicated.”
“What could it have been?” asked Pauline, her composure regained, her voice low and even.
Scofield looked at her. “It is said, Miss Stuart, that the only motives for murder are love, revenge or gain. Can you imagine any one of these directed toward your aunt?”
Pauline replied tranquilly. Evidently she had fully recovered her poise. “I can think of no one who could have killed my aunt for love; it is improbable that she has ever done any one such wrong as to call for such a deed in revenge; as to gain, if you mean pecuniary gain, all the legatees mentioned in her will may be said to have that motive.”
Pauline’s manner and tones were so impersonal, so scathingly ironic as to amount to a disclaimer for all the legatees. Her way of suggesting it made it seem so far removed from possibility that it was far more emphatic than any denial could have been.
But Coroner Scofield was as unmoved as his witness.
“Quite so,” he said coolly; “and therefore inquiries must be made. Did you, Miss Stuart, after leaving your aunt soon after midnight see or hear anything unusual or suspicious?”
“What do you mean by unusual or suspicious?”
“I mean did you see or hear anything, anything at all, that you could not explain to yourself as being in any way connected with the tragedy we are investigating?”
Before answering, Pauline looked in turn at all the members of the household. Haviland slowly turned his head as if to look at something across the room, and as slowly brought it back to its previous position.
