“Is it Mr. Bob?”

“Yes,” admitted Betty. “He’s different from the Bob Galvin that I expected. I can’t explain it, Hodgson, but—”

“You are right, Miss Betty,” said the servant, in a low voice. “He is different — different since last night!”

“Since last night!”

“Yes, ma’am. He went out with Mr. Mallory. That was about midnight. He came back an hour later, and I spoke to him when he came in. He didn’t say anything. He just went up to his room.

“To-day, when he spoke to me, he seemed changed. There was a difference in his voice, Miss Betty.”

The old servant’s words were perplexing.

Why had Bob Galvin gone out late — with Mallory, of all persons? Perhaps Hodgson was mistaken about Mallory. But he could not be mistaken about Bob.

Who was the visitor here tonight?

Betty wondered. She rose from the table and went out into the hall. There she encountered Bob Galvin and another man coming from the study.
