The comparison was long and careful, but unsatisfactory. Mr. Undercliff could not conscientiously say whether Hand had written the forged note or not. There were pros and cons.

"We are in deeper water than I thought," said he. "The comparison must be enlarged. You must write as I suggested, and get another note out of Mr. Hand."

"And leave the prayer-book with me," said Mrs. Undercliff.

Helen complied with these instructions, and in due course received a civil line from Mr. Hand, to say that the extracts had been sent him from the country by one of his fellow-clerks, and he had locked them up, lest Mr. Michael Penfold, who was much respected in the office, should see them. He could not say where they came from; perhaps from some provincial paper. If of any value to Miss Rolleston, she was quite at liberty to keep them. He added there was a coffee-house in the city where she could read all the London papers of that date. This letter, which contained a great many more words than the other, was submitted to Undercliff. It puzzled him so that he set to work, and dissected every curve the writer's pen had made; but he could come to no positive conclusion, and he refused to utter his conjectures.

"We are in a deep water," said he.

Finally, he told his mother he was at a stand-still for the present.

"But I am not," said Mrs. Undercliff. She added, after a while, "I think there's felony at the bottom of this."

"Smells like it to me," said the expert.
