“What the devil do you mean by this, Mr. Holmes? Do you dismiss my case?”

“Well, Mr. Gibson, at least I dismiss you. I should have thought my words were plain.”

“Plain enough, but what’s at the back of it? Raising the price on me, or afraid to tackle it, or what? I’ve a right to a plain answer.”

“Well, perhaps you have,” said Holmes. “I’ll give you one. This case is quite sufficiently complicated to start with without the further difficulty of false information.”

“Meaning that I lie.”

“Well, I was trying to express it as delicately as I could, but if you insist upon the word I will not contradict you.”

I sprang to my feet, for the expression upon the millionaire’s face was fiendish in its intensity, and he had raised his great knotted fist. Holmes smiled languidly and reached his hand out for his pipe.

“Don’t be noisy, Mr. Gibson. I find that after breakfast even the smallest argument is unsettling. I suggest that a stroll in the morning air and a little quiet thought will be greatly to your advantage.”

With an effort the Gold King mastered his fury. I could not but admire him, for by a supreme self-command he had turned in a a minute from a hot flame of anger to a frigid and contemptuous indifference.

“Well, it’s your choice. I guess you know how to run your own business. I can’t make you touch the case against your will. You‘ve done yourself no good this morning, Mr. Holmes, for I have broken stronger men than you. No man ever crossed me and was the better for it.”

“So many have said so, and yet here I am,” said Holmes, smiling. “Well, good-morning, Mr. Gibson. You have a good deal yet to learn.”

Our visitor made a noisy exit, but Holmes smoked in imperturbable silence with dreamy eyes fixed upon the ceiling.

“Any views, Watson?” he asked at last.

“Well, Holmes, I must confess that when I consider that this is a man who would certainly brush any obstacle from his path, and when I remember that his wife may have been an obstacle and an object of dislike, as that man Bates plainly told us, it seems to me —”

“Exactly. And to me also.”

“But what were his relations with the governess, and how did you discover them?”

“Bluff, Watson, bluff! When I considered the passionate, unconventional, unbusinesslike tone of his letter and contrasted it with his self-contained manner and appearance, it was pretty clear that there was some deep emotion which centred upon the accused woman rather than upon the victim. We’ve got to understand the exact relations of those three people if we are to reach the truth. You saw the frontal attack which I made upon him, and how imperturbably he received it. Then I bluffed him by giving him the impression that I was absolutely certain, when in reality I was only extremely suspicious.”

“Perhaps he will come back?”

"Don't you think, monsieur le secretaire-general, that this broken bit of ivory which was picked up on the ground... "

"No, M. Nicole, no. That bit of ivory belongs to something which we do not know and which its owner will at once make it his business to conceal. In order to trace the owner, we should at least be able to define the nature of the thing itself."

M. Nicole reflected and then began:

"Monsieur le secretaire-general, when Napoleon I fell from power... "

"Oh, M. Nicole, oh, a lesson in French history!"

"Only a sentence, monsieur le secretaire-general, just one sentence which I will ask your leave to complete. When Napoleon I fell from power, the Restoration placed a certain number of officers on half-pay. These officers were suspected by the authorities and kept under observation by the police. They remained faithful to the emperor's memory; and they contrived to reproduce the features of their idol on all sorts of objects of everyday use; snuff-boxes, rings, breast-pins, pen-knives and so on."

"Well?"

"Well, this bit comes from a walking-stick, or rather a sort of loaded cane, or life-preserver, the knob of which is formed of a piece of carved ivory. When you look at the knob in a certain way, you end by seeing that the outline represents the profile of the Little Corporal. hat you have in your hand, monsieur le secretaire-general, is a bit of the ivory knob at the top of a half-pay officer's life-preserver."

"Yes," said Prasville, examining the exhibit, "yes, I can make out a profile... but I don't see the inference... "

"The inference is very simple. Among Daubrecq's victims, among those whose names are inscribed on the famous list, is the descendant of a Corsican family in Napoleon's service, which derived its wealth and title from the emperor and was afterward ruined under the Restoration. It is ten to one that this descendant, who was the leader of the Bonapartist party a few years ago, was the fifth person hiding in the motor-car. Need I state his name?"

"The Marquis d'Albufex?" said Prasville.

"The Marquis d'Albufex," said M. Nicole.

M. Nicole, who no longer seemed in the least worried with his hat, his glove and his umbrella, rose and said to Prasville:

"Monsieur le secretaire-general, I might have kept my discovery to myself, and not told you of it until after the final victory, that is, after bringing you the list of the Twenty-seven. But matters are urgent. Daubrecq's disappearance, contrary to what his kidnappers expect, may hasten on the catastrophe which you wish to avert. We must therefore act with all speed. Monsieur le secretaire-general, I ask for your immediate and practical assistance."

"In what way can I help you?" asked Prasville, who was beginning to be impressed by his quaint visitor.

"By giving me, to-morrow, those particulars about the Marquis d'Albufex which it would take me personally several days to collect."

Prasville seemed to hesitate and turned his head toward Mme. Mergy. Clarisse said:

"I beg of you to accept M. Nicole's services. He is an invaluable and devoted ally. I will answer for him as I would for myself."
