“When I told Major Benson this morning about Mr. Pfyfe and his brother, he said at once that I should come with him to your office and tell you also. But on the way over, he suggested that I might omit a part of the story. He didn’t exactly tell me not to mention it; but he explained that it had nothing to do with the case and might only confuse you. I followed his suggestion; but after I got back to the office I began thinking it over, and knowing how serious a matter Mr. Benson’s death was, I decided to tell you anyway. In case it did have some bearing on the situation, I didn’t want to be in the position of having withheld anything from you.”

She seemed a little uncertain as to the wisdom of her decision.

“I do hope I haven’t been foolish. But the truth is, there was something else besides that envelope, which Mr. Benson asked me to bring him from the safe the day he and Mr. Pfyfe had their quarrel. It was a square heavy package, and, like the envelope, was marked ‘Pfyfe-Personal’. And it was over this package that Mr. Benson and Mr. Pfyfe seemed to be quarrelling.”

“Was it in the safe this morning when you went to get the envelope for the Major?” asked Vance.

“Oh, no. After Mr. Pfyfe left last week, I put the package back in the safe along with the envelope. But Mr. Benson took it home with him last Thursday—the day he was killed.”

Markham was but mildly interested in the recital, and was about to bring the interview to a close when Vance spoke up.

“It was very good of you, Miss Hoffman, to take this trouble to tell us about the package; and now that you are here, there are one or two questions I’d like to ask. . . . How did Mr. Alvin Benson and the Major get along together?”

She looked at Vance with a curious little smile.

“They didn’t get along very well,” she said. “They were so different. Mr. Alvin Benson was not a very pleasant person, and not very honorable, I’m afraid. You’d never have thought they were brothers. They were constantly disputing about the business; and they were terribly suspicious of each other.”

“That’s not unnatural,” commented Vance, “seeing how incompatible their temp’raments were. . . . By the bye, how did this suspicion show itself?”
