Edward Undercliff was at work at lithographing. He received Helen cordially, nodded to Burt, and said she could not have a better assistant.

He then laid his fac-simile of the forged note on the table, with John Wardlaw's genuine writing and Penfold's indorsement. "Look at that, Mr. Burt."

Burt inspected the papers keenly.

"You know, Burt, I swore at Robert Penfold's trial that he never wrote that forged note."

"The other day this lady instructed me to discover, if I could, who did write the forged note. But, unfortunately, the materials she gave me were not sufficient. But, last night, a young man dropped from the clouds, that I made sure was an agent of yours, Miss Rolleston. Under that impression I was rather unguarded, and I let him know how far we had got, and could get no further. 'I think I can help you,' says this young man, and puts a letter on the table. Well, Mr. Burt, a glance at that letter was enough for me. It was written by the man who forged the note."

"Yes. I'll put the letter by the side of the forged note; and, if you have any eye for writing at all, you'll see at once that one hand wrote the forged note and this letter. I am also prepared to swear that the letters signed Hand are forgeries by the same person." He then coolly put upon the table the letter from Arthur Wardlaw that Helen had received on board the _Proserpine,_ and was proceeding to point out the many points of resemblance between the letter and the document, when he was interrupted by a scream from Helen.

"Ah!" she cried, "he is here. Only one man in the world could have brought that letter. I left it on the island. Robert is here. He gave you that letter."

"You are right," said the expert, "and what a fool I must be! I have no eye except for handwriting. He had a beard; and such a beard!"
