me were openly embarrassed at the guilt of their race in

"Well, then, I looked at the reverse side, and I found seven misprints in one slip, and five in the other. That was a great number to creep into printed slips of that length. The trial part did not show a single erratum. 'Hullo!' said I to myself; 'why, one side is printed more carefully than the other.' And that was not natural. The printing of advertisements is looked after quite as sharply as any other part in a journal. Why, the advertisers themselves cry out if they are misprinted!"

"Child's play," said the expert. "Well, from that blot I went on. I looked at the edges, and they were cut too clean. A gentleman with a pair of scissors can't cut slips out of a paper like this. They were cut in the printer's office. Lastly, on holding them to the light, I found they had not been machined upon the plan now adopted by all newspapers; but worked by hand. In one word--forgeries!"

"Oh," said Helen, "to think I should have handled forgeries, and shown them to you for real. Ah! I'm so glad; for now I have committed the same crime as Robert Penfold; I have uttered a forged document. Take me up, and have me put in prison, for I am as guilty as ever he was." Her face shone with rapture at sharing Robert's guilt.

The expert was a little puzzled by sentiments so high-flown and unpractical.

"I think," said he, "you are hardly aware what a valuable discovery this may prove to you. However, the next step is to get me a specimen of the person's handwriting who furnished you with these. The chances are he is the writer of the forged note."

Helen uttered an exclamation that was almost a scream. The inference took her quite by surprise. She looked at Mrs. Undercliff.

"He is right, I think," said the old lady.

"Right or wrong," said the expert, "the next step in the inquiry is to do what I said. But that demands great caution. You must write a short civil note to Mr. Hand, and just ask him some question. Let me see. Ask him what newspapers his extracts are from, and whether he has got any more. He will not tell you the truth; but no matter, we shall get hold of his handwriting."
