But whether Bendigo's diary might have proved valuable remained a matter of doubt, for when Jenny opened the parcel, it was not there. A blank book and the famous novel were all the parcel contained.

"But I packed it myself," said Mr. Redmayne. "The diary was bound exactly as this blank volume is bound, yet it is certain that I made no mistake, for I opened my brother's log and read a page or two before completing the parcel."

"He had bought a new diary only the last time he was in Dartmouth," said Doria. "I remember the incident. I asked him what he was going to put into the book, and he said that his log was just running out and he needed a new volume."

"You are sure that you did not mistake the old, full book for the new, empty one, Albert?" asked his friend.

"I cannot be positive, of course, but I feel no shadow of doubt in my own mind."

"Then the one has been substituted for the other by somebody else. That is a very interesting fact, if true."

"Impossible," declared Jenny. "There was nobody to do such a thing, Mr. Ganns. Who could have felt any interest in poor Uncle Bendigo's diary but ourselves?"

Mr. Ganns considered.

"The answer to that question might save us a very great deal of trouble," he said. "But there may be no answer. Your uncle may be mistaken. On the other hand I have never known him to be mistaken over any question involving a book."

He took up the empty volume and turned its pages; then Brendon declared they must be going.
