"Was Lady Hereward killed in the Tower?" the woman wanted to know.
"Yes," said the detective.
"That looks rather queer against Mr. Barr, hating her as he did," Miss Maunsell reflected aloud. "Well, well, if he has committed a murder, the sooner it's brought home to him the better, say I. I wouldn't put out my hand to save a brother, if I had one, from justice, so be that he was guilty."
"Had Barr a revolver?" Gaylor asked.
"Oh, yes; he used to keep it in a drawer of his writing desk. Not that I was one to pry; but he didn't try to hide the thing. Sometimes the drawer was left half open, and I couldn't help seeing what was in it, when I was putting the room to rights."
At this, the detective produced a small, new revolver. It had been obtained for this very purpose; that it might be shown to the late housekeeper of Ian Barr. The bullet which had killed Lady Hereward had been extracted from her dead body, and another exactly like it had been found embedded in the wall of the Tower room. As yet, it had not been discovered by whom these cartridges had been sold or bought, nor had the revolver been found, despite diligent search. But the bullets exactly fitted the weapon purchased and brought to Yorkshire by the detective; therefore, it stood to reason that the missing revolver was of the same calibre and of more or less the same description.
