"He tells nobody more than he can help," she said. "You are no worse treated than any one else he works with. But it is a little annoying sometimes."

"For instance, do you know what he is doing to-night?" I asked.

There was no mistaking the criticism in the little shrug with which she replied—

"I half suspect he is walking about in the dark by himself just to make me think he is busy on some mysterious affair!"

"Do you actually mean that?" I exclaimed.

"No, no," she said hastily, "not really quite that! But he sometimes tempts one to say these things."

"Have you worked with him often before?"

"Enough to know his little peculiarities." She smiled suddenly. "Oh, he is a very wonderful man, is my dear brother!"

Again I was delighted (I confess it shamelessly!) to hear that unmistakable note of criticism.

"'Wonderful' may have several meanings," I suggested.
