“Why?”

“I think it wiser for all concerned—­for all concerned—­that the tale shall not become public property.”

“But why?”

“Oh, my land!” burst out Fibsy; “don’t you see?  The ghost was Mrs, Embury!”

The boy had put into words what was in the thoughts of both Stone and Elliott.  They realized that, while Aunt Abby’s experience might have been entirely a dream, it was so circumstantial as to indicate a real occurrence, and in that case, what solution so plausible as that Eunice, after committing the crime, wandered into her aunt’s room, and whether purposely or accidentally, dropped the implement of death?

Stone, bent on investigation, plied Miss Ames with questions.

Elliott, sorely afraid for Eunice, begged the old lady not to answer.

“You are inventing!” he cried.  “You are drawing on your imagination!  Don’t believe all that, Mr. Stone.  It isn’t fair to—­to Mrs, Embury!”

“Then you see it as I do, Mr. Elliott?” and Stone turned to him quickly.  “But, even so, we must look into this story.  Suppose, as an experiment, we build up a case against Mrs, Embury, for the purpose of knocking it down again.  A man of straw—­you know.”

“Don’t,” pleaded Elliott.  “Just forget the rigmarole of the nocturnal vision—­and devote your energies to finding the real murderer.  I have a theory—­”

“Wait, Mr. Elliott, I fear you are an interested investigator.  Don’t forget that you have been mentioned as one of those with ‘motive but no opportunity.’ "

“Since you have raised that issue, Mr. Stone, let me say right here that my regard for Mrs, Embury is very great.  It is also honorable and lifelong.  I make no secret of it, but I declare to you that its very purity and intensity puts it far above and beyond any suspicion of being ‘motive’ for the murder of Mrs, Embury’s huband.”

Mason Elliott looked Fleming Stone straight in the eye and the speaker’s tone and expression carried a strong conviction of sincerity.

Fibsy, too, scrutinized Elliott.

“Good egg!” he observed to himself; “trouble is—­he’d give us that same song and dance if he’d croaked the guy his own self!”

“Furthermore,” Stone went on, “Mrs, Embury shows a peculiarly strong repugnance to hearing this story of Miss Ames’ experience.  That looks—­”

“Oh, fiddlesticks!” cried Miss Ames, who had been listening in amazement; “it wasn’t Eunice!  Why would she rig up in Sanford’s gym jersey?”

“Why wouldn’t she?” countered Stone.  “As I said, we’re building up a supposititious case.  Assume that it was Mrs, Embury, not at all enacting a ghost, but merely wandering around after her impulsive deed—­for if she is the guilty party it must have been an impulsive deed.  You know her uncontrollable temper—­her sudden spasms of rage—­”

“Mr. Stone, a ‘man of straw,’ as you call it, is much more easily built up than knocked down.”  Elliott spoke sternly.  “I hold you have no right to assume Mrs, Embury’s identity in this story Miss Ames tells.”
