Minny was with her, but the older sister, in quieter attire, was merely a foil for the ebullient Jenny. Also, they were accompanied by a big, good-natured faced man, whom I recognized at once as the janitor of the Matteawan Building, and who, it transpired, was the father of the two girls.

“Here we are,” he said, in a bluff, hearty way; “here’s me and my girls, and we’d be obliged, Mr. Chief, if you’d cut it short as much as you can, for me and Minny wants to get back.”

“All right, Boyd,” and Chief Martin smiled at him. “I’ll tackle you first. Tell us all about that private elevator of Mr. Gately’s.”

“I will, but savin’ for this murder business, not a word of it would ever have crossed my lips. Well, Mr. Gately, he owned the Matteawan, d’you see? and when it suited his purposes to put in a private elevator up to his rooms on the top floor of the next door building,—The Puritan Building, you know,—what more easy than to run the shaft up in the one building with the opening at the top out into the other house. Anyways, that’s what he done,—a long time ago. I had to know of it, of course,——”

“Of course, as superintendent of the Matteawan.”

“That’s what they call it now, but I like better to be called janitor. As janitor I began, and as janitor I’ll work to the end. Well, Mr. Gately, he went up and down in the little car whenever he chose, and no one noticed him at all. It wasn’t, after all, to say, secret, exactly, but it was a private elevator.”

“But a concealed door in his own office makes the thing pretty secret, I should say.”

“Secret it is, then. But it’s no crime for a man to have a concealed way of gettin’ into or out of his own rooms, is it? Many’s the time Mr. Gately’s come down laughing fit to bust at the way he got away from some old doddering fool who wanted to buzz him to death!”

“You frequently saw him come down, then?”

“Not to say frequently,—but now and again. If I happened to be about at the time.”
