work.”

“Excellent!” cried Carrados. “Do you unearth many murders?”

“No,” admitted Mr Carlyle; “our business lies mostly on the conventional lines among divorce and defalcation.”

“That’s a pity,” remarked Carrados. “Do you know, Louis, I always had a secret ambition to be a detective myself. I have even thought lately that I might still be able to do something at it if the chance came my way. That makes you smile?”

“Well, certainly, the idea——”

“Yes, the idea of a blind detective—the blind tracking the alert——”

“Of course, as you say, certain faculties are no doubt quickened,” Mr Carlyle hastened to add considerately, “but, seriously, with the exception of an artist, I don’t suppose there is any man who is more utterly dependent on his eyes.”

Whatever opinion Carrados might have held privately, his genial exterior did not betray a shadow of dissent. For a full minute he continued to smoke as though he derived an actual visual enjoyment from the blue sprays that travelled and dispersed across the room. He had already placed before his visitor a box containing cigars of a brand which that gentleman keenly appreciated but generally regarded as unattainable, and the matter-of-fact ease and certainty with which the blind man had brought the box and put it before him had sent a questioning flicker through Carlyle’s mind.

“You used to be rather fond of art yourself, Louis,” he remarked presently. “Give me your opinion of my latest purchase—the bronze lion on the cabinet there.” Then, as Carlyle’s gaze went about the room, he added quickly: “No, not that cabinet—the one on your left.”

Carlyle shot a sharp glance at his host as he got up, but Carrados’s expression was merely benignly complacent. Then he strolled across to the figure.

“Very nice,” he admitted. “Late Flemish, isn’t it?”

“No. It is a copy of Vidal’s ‘Roaring lion.’”

“Vidal?”

“A French artist.” The voice became indescribably flat. “He, also, had the misfortune to be blind, by the way.”

“You old humbug, Max!” shrieked Carlyle, “you’ve been thinking that out for the last five minutes.” Then the unfortunate man bit his lip and turned his back towards his host.

“Do you remember how we used to pile it up on that obtuse ass Sanders and then roast him?” asked Carrados, ignoring the half-smothered exclamation with which the other man had recalled himself.

“Yes,” replied Carlyle quietly. “This is very good,” he continued, addressing himself to the bronze again. “How ever did he do it?”

“With his hands.”

“Naturally. But, I mean, how did he study his model?”

“Also with his hands. He called it ‘seeing near.’”

“Even with a lion—handled it?”

“In such cases he required the services of a keeper, who brought the animal to bay while Vidal exercised his own particular gifts.... You don’t feel inclined to put me on the track of a mystery, Louis?”

Unable to regard this request as anything but one of old Max’s unquenchable pleasantries, Mr Carlyle was on the point of making a suitable reply when a sudden thought caused him to smile knowingly. Up to that point he had, indeed, completely forgotten the object of his visit. Now that he remembered the doubtful Dionysius and Mr Baxter’s recommendation he immediately assumed that some mistake had been made. Either Max was not the Wynn Carrados he had been seeking or else the dealer had been misinformed; for although his host was wonderfully expert in the face of his misfortune, it was inconceivable that he could decide the genuineness of a coin without seeing it. The opportunity seemed a good one of getting even with Carrados by taking him at his word.

“Yes,” he accordingly replied, with crisp deliberation, as he recrossed the room; “yes, I will, Max. Here is the clue to what seems to be a rather remarkable fraud.” He put the tetradrachm into his host’s hand. “What do you make of it?”

For a few seconds Carrados handled the piece with the delicate manipulation of his finger-tips while Carlyle looked on with a self-appreciative grin. Then with equal gravity the blind man weighed the coin in the balance of his hand. Finally he touched it with his tongue.

“Well?” demanded the other.

“Of course I have not much to go on, and if I was more fully in your confidence I might come to another conclusion——”

“Yes, yes,” interposed Carlyle, with amused encouragement.

“Then I should advise you to arrest the parlourmaid, Nina Brun, communicate with the police authorities of Padua for particulars of the career of Helene Brunesi, and suggest to Lord Seastoke that he should return to London to see what further depredations have been made in his cabinet.”

Mr Carlyle’s groping hand sought and found a chair, on to which he dropped blankly. His eyes were unable to detach themselves for a single moment from the very ordinary spectacle of Mr Carrados’s mildly benevolent face, while the sterilized ghost of his now forgotten amusement still lingered about his features.

“Good heavens!” he managed to articulate, “how do you know?”

“Isn’t that what you wanted of me?” asked Carrados suavely.

“Don’t humbug, Max,” said Carlyle severely. “This is no joke.” An undefined mistrust of his own powers suddenly possessed him in the presence of this mystery. “How do you come to know of Nina Brun and Lord Seastoke?”

“You are a detective, Louis,” replied Carrados. “How does one know these things? By using one’s eyes and putting two and two together.”

Carlyle groaned and flung out an arm petulantly.

“Is it all bunkum, Max? Do you really see all the time—though that doesn’t go very far towards explaining it.”

“Like Vidal, I see very well—at close quarters,” replied Carrados, lightly running a forefinger along the inscription on the tetradrachm. “For longer range I keep another pair of eyes. Would you like to test them?”

Mr Carlyle’s assent was not very gracious; it was, in fact, faintly sulky. He was suffering the annoyance of feeling distinctly unimpressive in his own department; but he was also curious.

“The bell is just behind you, if you don’t mind,” said his host. “Parkinson will appear. You might take note of him while he is in.”

The man who had admitted Mr Carlyle proved to be Parkinson.

“This gentleman is Mr Carlyle, Parkinson,” explained Carrados the moment the man entered. “You will remember him for the future?”

Parkinson’s apologetic eye swept the visitor from head to foot, but so lightly and swiftly that it conveyed to that gentleman the comparison of being very deftly dusted.

“I will endeavour to do so, sir,” replied Parkinson; turning again to his master.

“I shall be at home to Mr Carlyle whenever he calls. That is all.”

“Very well, sir.”

“Now, Louis,” remarked Mr Carrados briskly, when the door had closed again, “you have had a good opportunity of studying Parkinson. What is he like?”

“In what way?”

“I mean as a matter of description. I am a blind man—I haven’t seen my servant for twelve years—what idea can you give me of him? I asked you to notice.”

“I know you did, but your Parkinson is the sort of man who has very little about him to describe. He is the embodiment of the ordinary. His height is about average——”

“Five feet nine,” murmured Carrados. “Slightly above the mean.”

“Scarcely noticeably so. Clean-shaven. Medium brown hair. No particularly marked features. Dark eyes. Good teeth.”

“False,” interposed Carrados. “The teeth—not the statement.”

“Possibly,” admitted Mr Carlyle. “I am not a dental expert and I had no opportunity of examining Mr Parkinson’s mouth in detail. But what is
