"He might have bought them in London," I said.

"I think it was Birmingham," said Quarles.

So far he was right. It was the third place we visited. Baines and Son was the firm, and we saw old Mr. Baines. He had constantly sold books to Mr. Parrish, of Thornfield, who had been to his shop several times, but their intercourse was chiefly by correspondence. Good books!

Certainly. Mr. Parrish knew what he was doing, and never bought rubbish.

"His purchases might be expected to increase in value?" asked Quarles.

"Yes; but, forgive me, why these questions?"

"Ah! I supposed you would have heard. Mr. Parrish is dead."

"Indeed! I am very sorry to hear it."

"We are looking into his affairs," Quarles went on. "Is there any money owing to you?"

"No."

"The fact is, Mr. Parrish was murdered."

"Murdered!" exclaimed Baines, starting from his chair. "Do you mean for some treasured volume he possessed? Do you mean by some bibliomaniac?"

"You think he may have had such a treasure, then?"

"I know he had many rare and valuable books," Baines answered.

"You don't happen to know a bibliomaniac who might commit murder?"

said Quarles.

"No."

"Such information would help us, because a young man has been condemned for the murder, a man named Hall--Michael Hall."

"I never heard of him," said Baines. "I wonder I did not see the case in the paper."

"It caused little sensation," said Quarles. "At present it seems one of those crimes committed for small gain."

"Mr. Parrish must have been a man of considerable means," said the bookseller; "considerable means, although he was eccentric about money. He always sent me cash, or some check he had received, with a request that I would return him the balance in cash. Indeed, I have constantly acted as his banker. He has sent me checks and asked me to send him notes for them."

"Where did those checks come from--I mean whose were they? Were they for dividends?"

"Possibly, one or two of them, I do not remember; but I fancy he sold books sometimes, and the checks represented the purchase money."

We thanked Mr. Baines, and then, just as we were leaving, Quarles said:

"By the way, do you happen to know a Mr. Charles Eade?"

"A solicitor?" queried the bookseller.

"I didn't know he was a solicitor, but he is a relation of Mr.

Parrish's, I believe," Quarles answered.

"I was not aware of that," Baines returned. "Mr. Eade's office is in West Street--No. 40, I think. He comes in here occasionally to make small purchases."

"Not a bookworm like his uncle, eh?"

"Neither the taste nor the money, I should imagine," said Baines.

As soon as we were in the street the professor turned to me.

"That has been an interesting interview, Wigan. What do you think of the bibliomaniac idea?"

"I suppose it goes to confirm your theory?" I said.

"On the contrary, it was a new idea to me. It would be an idea well worth following if we found that one or two of Parrish's valuable books were missing; but we'll try another trail first. I think we will go to Persh.o.r.e next."

"How about Charles Eade?"

"I expect he is in his office in West Street. I don't want to see him.

Do you?"

"We might call upon him so as to leave no stone unturned. I don't think you quite appreciate the difficulty of this case. The man may be innocent, but we have got to prove it."

"My dear Wigan, if Baines had said that Eade was a bibliomaniac I should have gone to West Street at once. Since he is only a lawyer, I am convinced we should get no useful information out of him. Besides, he might very reasonably resent our interference in his uncle's affairs. It will be time enough to communicate with him when we have made some discovery which will help Michael Hall."

Next morning we journeyed to Persh.o.r.e.

"Yesterday you suggested that I had a theory, Wigan," said Quarles, who had been leaning back in the corner of the railway carriage apparently asleep, but now became mentally energetic. "As a fact, my theory went no further than this: A bookworm in all probability buys books; to buy books requires money; therefore he must have money. In Thornfield Mr. Parrish was considered a man of means; our friend Baines confirms that belief. My theory is established."

"It doesn't carry us very far," I said.

"It provides another motive for the murder--robbery. The bookseller's story suggests that Parrish must have kept a considerable sum of money in the house. It is said nothing was taken, but a large amount in notes may be stolen without leaving any noticeable s.p.a.ce vacant. Just one step forward we may take. If such a sum existed, as is probable, remember Parrish might at times think of burglars, might have mentioned his fears, without giving a reason, to Hall, and Hall, having a life-preserver, might make a present of it to his friend."

I did not contradict him, but, personally, I was not at all convinced.

From the station we went straight to the p.a.w.nbroker's and had an interview with the a.s.sistant who had identified Hall as the man who p.a.w.ned the salver. We arranged that I was a detective helping the professor, who was interested in Hall, and could not believe that he was guilty. It proved an excellent line to adopt, for it brought out the young fellow's sympathy. I asked questions, after stating our position, and for a time Quarles remained an interested listener. The a.s.sistant described Hall fairly accurately.

"He had p.a.w.ned things before, hadn't he?" I asked.

"Yes."

"You recognized Hall at once?"

"Yes----"

"There is one very curious point," I said: "so long as the articles were his own, and he had a right to p.a.w.n them, he gave a false name; yet, when he p.a.w.ns an article he had stolen, he gave his own name."

"I think it seems more curious than it is," was the answer. "My experience is that whenever an important article is p.a.w.ned the correct name is given. The affair becomes a financial transaction which there is no reason to be ashamed of."
