CHAPTER XXIII. THE CYPHER.

When the messenger had been despatched, Naball drew his seat up to the table, and began to make some notes, after which he turned to Eugénie.

"I was firmly convinced of Stewart's guilt," he said quietly; "but what you have told me throws a new light on the subject. I said you could not do that--I beg your pardon--you can."

Eugénie bowed her head in acknowledgment of the apology, and asked him a question in a hesitating manner.

"You don't think Caprice is guilty?"

"I think nothing at present," he replied evasively; "not even that Stewart is innocent. When I see the boy, I'll tell you what I think."

They talked on together for a few minutes, and then there came a knock at the door. In reply to Ezra's permission to enter, the door opened, and Isaiah appeared on the threshold, holding some papers in his hand.

"Oh, you've come," said Ezra, as the boy shut the door after him.

"Yes; did you want me?" demanded Isaiah in a jerky manner, "'cos I never knowed you did."

"Didn't you meet a messenger?" asked Naball, turning his head round.

Isaiah deposited the papers he carried on Ezra's desk, and shook his head.

"No, I never met any one, I didn't," he answered. "Mr. Ezra asked me to bring all letters that came to the old 'un, so as these came, I did."

"That's right," said Lazarus, looking through the letters. "By-the-way, Isaiah, this gentleman wants to ask you a few questions."

"What, Mr. Naball?" said Isaiah in alarm. "Oh, sir, I never had nothing to do with it."

Naball smiled.

"No! no! that's all right," he said good-naturedly. "It would take a bigger man than a sprat like you to commit such a crime; but, tell me, do you know Caprice?"

Isaiah leered significantly.

"I've seen her on the stage, that's all."

"Never off?"

"Drivin' about the streets."

"Anywhere else?"

Isaiah glanced uneasily at Ezra, who laughed.

"Go on, Isaiah; it's all right."

"Well, I've seen her at the old 'un's place."

"Oh, indeed," said Naball quickly. "Often?"

"Yes--lots of times--at night--came to do business, I s'pose."

"When did you see her last?"

"Oh, not for a long time," replied Isaiah; "but do you remember the week them diamonds were stolen?"

"Yes, yes," said Naball eagerly.

Isaiah nodded.

"Well, she came to see the old 'un, then."

Naball suppressed his exultation¹ with difficulty, and asked Isaiah another question.

"I say--those bank-notes that were stolen--"

"I never stole 'em."

"No one said you did," retorted Naball tartly²; "but you wrote something on the back of one of 'em."

Isaiah turned scarlet³, and shifted from one leg to the other.

"Well, you see," he murmured apologetically, "Mr. Stewart wanted to know a good 'un to back for the Cup, so I was afraid of the old 'un hearing, and as there wasn't no paper, I wrote on the back of one of 'em, 'Back Flat-Iron.'"

"In pencil?"

"No, in ink. Mr. Stewart, he laughs and nods, then puts the notes in the cash box, and puts 'em in the safe."

"That's all right," said Naball, dismissing him; "you can go."

Isaiah put on his hat, put his hands in his pockets, and departed, whistling a tune⁴. When the door closed on him, Naball turned to his two companions with an exulting⁵ light in his eyes.

"What do you think now, Mr. Naball?" asked Eugénie.

"Think. I think as I've done all along," he replied. "Caprice stole those jewels herself, and sold them to old Lazarus."

"But what's that got to do with the death of my father?" asked Ezra.

"Perhaps nothing--perhaps a lot," said the detective. "I don't know but that boy's evidence has given me a clue. Suppose--I'm only supposing, mind you--Caprice stole her own diamonds, with Villiers as an accomplice⁶. Suppose she took them to old Lazarus and sold 'em. Suppose Villiers, thinking the old man has them in his safe, goes to rob him, and commits the murder to do so. Suppose all that--I should think there would be a very pretty case against Villiers."

"Yes; but Keith's knife?" said Eugénie.

"Ah, now you have me," answered Naball, puzzled. "I don't know, unless Villiers managed to get it while Stewart was fighting with him on that night, and covered it in blood in order to throw suspicion on him."

"All your ideas are theoretical," said Ezra drily. "Perhaps Caprice never stole her own jewels, or sold them to my father."

"Yes, she did, I'll swear," retorted Naball decisively. "Why wouldn't she prosecute⁷? why did I find Villiers with one of the jewels? You bet, she stole them for some freak, and I daresay Villiers committed the murder to get them back."

"I don't think my father would have kept such valuable jewels as that about the premises⁸."

"No; he'd put 'em in the bank."

"No, he wouldn't," retorted Ezra; "he sent all his jewels to Amsterdam. And here," holding up a letter, "is an envelope with the Dutch postmark."

"By Jove!" ejaculated Naball, under his breath, "what a queer thing if it should turn out to be those diamonds of Caprice's. Open the letter."

"Suppose it does turn out to be the diamonds," said Ezra, slowly tearing the envelope.

"Well"--Naball drew a long breath--"it will be the beginning of the end."

"I hope it will end in Keith's being released," said Eugénie, looking at Ezra with intense anxiety.

That gentleman took out the letter, and glancing at it for a moment, gave vent⁹ to an ejaculation of disgust.

"What's the matter?" asked Eugénie and Naball together.

"The letter is in cypher," said Lazarus, tossing it over to the detective. "I don't think we'll be able to read it."

"Oh, we'll have a try," said Naball, quickly spreading oat the letter. "Let's have a look at it."

The letter was as follows:--

"Dsidanmo seaf utnes teh ssteon ryiks sgenlil gto teher tdhnoaus sgennid it lses teher hduenrd bneiertns."

"What the deuce does it mean?" asked Naball in a puzzled tone.

"It's a cypher, evidently, of which my father alone possesses the key," said Ezra. "I'll have a look among his papers, and if I find it, it will soon make sense of this jumble¹⁰ of words."

"It's like a Chinese puzzle," observed Naball, glancing at it. "I never could find out these things."

"Let me look," said Eugénie, taking the letter. "I used to be rather good at puzzles."

"We'll find this one out," said Naball significantly, "and you'll do some good for Stewart."

"You think it's about Caprice's diamonds?" she asked.

"I think it's about Caprice's diamonds," he replied.

"I think the words have been written backwards," said Ezra, looking over her shoulder.

Eugénie shook her head.

"I don't think so," she replied, scanning the letter closely. "If so, the word 'it' would have been written 'ti.'"

"Try a word of three letters, if there's one," suggested Naball, "and you can see how the letters are placed."

"Here's one spelt 'g-t-o.' What word can be made out of that."

"Got," said Ezra eagerly.

"Well, if so, in the cypher it reads, the first letter 'g,' the last, letter 't,' and the middle letter at the end."

"What do you think of that?" asked Naball bluntly.

"That the sender of this has taken the first and last letters of a word, and written them in rotation¹¹."

"I don't understand," said Naball in a puzzled tone.

"I think I do," said Eugénie quickly. "Let us take another word, and instead of guessing it, try my idea, Here is a word, 'teher.' Now, Mr. Naball, take a sheet of paper and write down what I say."

Naball got some paper and a pencil.

"Now," said Eugénie, "this word 'teher.' The first letter is 't,' now the second letter, which, I think, is the end one of the proper word, is 'e'--place that at the end."

Naball wrote "t--e."

"The third letter of the cypher, and the second of the proper word, is 'h'--put that next the 't;' and the fourth letter of the cypher, and third of the proper word, is 'e'--place that at the end also."

Naball added two letters as instructed, "t,h--e,e."

"Now," said Eugénie, "there's only one letter left, which must naturally be in the middle."

Naball finished his writing thus: t-h-r-e-e.

"That is three," he said, with a cry of triumph. "By Jove! Miss Rainsford, you are clever; let's make certain, by trying another letter."

"Take 's-s-t-e-o-n,'" suggested Ezra.

Naball wrote the letters as follows:--

s -- s

t -- e

o -- n

Then he wrote them in a line, down the first column and up the second, which made the word "stones."

"Glad we've got it right, after all," he said delightedly, and then the whole three of them went to work on the same system, with the result that the letter read thus:--

"Diamonds safe, unset the stones, risky¹² selling, got three thousand, sending it less three hundred, bernstein."

"Ah!" said Naball when he read this, "wasn't I right?"

"So I think," said Ezra sadly; "my father evidently bought the jewels from her, and sent them to Amsterdam to be sold."

"Still," said Eugénie impatiently, "this does not clear up the mystery of the murder."

"You don't think Caprice did it?" said Ezra.

"No," replied the detective; "but Villiers might have done it in order to recover the jewels. But I tell you what, there's only one thing to be done, we'll go down and see Caprice."

This was agreed to, and without losing a moment they started.

"I may be wrong, as I was before," said Naball when they were in the train, "but I'll lay any money that Villiers has seen Caprice since the murder."

"You don't think she's an accomplice?" cried Eugénie.

"I think nothing," retorted Naball, "till I see Caprice."
