“And that makes one think of what the housekeeper said about the secretary,” was my comment.

There was a moment's silence, broken by Carter's saying:

“I wonder what the housekeeper meant by that remark. She certainly shut up like a clam when we tried to question her. There is something back of it—at least back of the housekeeper's attitude.”

“Well,” came Ranville's voice, “there is one thing sure; I think I am right when I say that whoever killed Warren was some one who knew him. He sat in that chair, the one across from the desk, and I think perhaps I am right when I add that he might have gone to Warren's side to say good-by and then plunged the knife into him. But why he paused to arrange the body on the floor and to make the cross on his forehead I cannot say, but—”

Just what he might have added I do not know. We were interrupted by the dog suddenly rising to his feet and starting to growl. Deep, heavy growls at some object we could not see. Then came the sound of footsteps on the walk, and a deep voice came from the lawn:

“Hearing voices, Mr. Carter, I could not resist stopping.”

As the man came up the steps, I pushed the dog behind my chair, telling him to be quiet. Carter rose and turned on the porch lamp. For a moment the light, after the dense darkness, blinded me. I wondered who could be coming to see Carter at this late hour. It was a very tall and an extremely thin man who accepted the chair which Carter pulled out. A man with a deep lined face and nervous shifting eyes. As he came over to the chair, I saw that he was wearing a clergyman's collar, though he did not look as calm as most of the clergymen I have seen.

He proved to be Carter's next-door neighbor, and he told us he was on his way home when he heard the sound of our voices. As he talked, I could see that he was of a nervous, restless disposition, for his hands were never still, and he moved his feet in an uneasy manner. His voice was rather harsh, though the English he used was perfect.

After the introductions had been acknowledged Carter said:

“Woods is my next-door neighbor. He's been in England, Ranville.”
