"Gone—stolen?" she exclaimed. It brought a smile to my face. For the first time in my experience of this pretty, little bunch of brains, she had hazarded a guess.

"Gone," I admitted coolly—a bit sarcastically. "I've no reason to say stolen."

"But—yes, you have—you have, Mr. Boyne! If it is gone, it was stolen. Is it gone—are you sure it is gone?" Eagerly her eyes were searching desk, cabinet, the shelf where the other diaries made their long row. I satisfied her on that score.

"I have searched the study thoroughly; it is not in this room."

"Was here last night," Worth cut in. "I saw it on the desk."

"And was stolen last night," Barbara reaffirmed, quickly. "These books are too big to be slipped into a pocket, so we can't believe it was left upon Mr. Gilbert's person; and he wouldn't lend it—wouldn't willingly let it go from his possession. So it was stolen; and the man who stole it—killed him." She shuddered.

That was going too swift for me to follow, but I saw on Worth Gilbert's face his acceptance of it. Either conviction of Barbara's infallibility, or some knowledge locked up inside his own chest, made him certain the diary had been stolen, and the thief was his father's murderer. In a flash, I remembered his words, "putting every damn' word of our row into it," and I shot straight at him,

"Did you take that book, Worth?"

He only shook his head and answered,

"You heard what Bobs said, Jerry."
