“Clutched, you say?”

“Yes, sir, we could hardly open the fingers.”

“That is of great importance. It excludes the idea that anyone could have placed the note there after death in order to furnish a false clue. Dear me! The note, as I remember, was quite short:

“I will be at Thor Bridge at nine o’clock.”

“G. DUNBAR.

Was that not so?”

“Yes, sir.”

“Did Miss Dunbar admit writing it?”

“Yes, sir.”

“What was her explanation?”

“Her defence was reserved for the Assizes. She would say nothing.”

“The problem is certainly a very interesting one. The point of the letter is very obscure, is it not?”

“Well, sir,” said the guide, “it seemed, if I I may be so bold as to say so, the only really clear point in the whole case.”

Holmes shook his head.

“Granting that the letter is genuine and was really written, it was certainly received some time before — say one hour or two. Why, then, was this lady still clasping it in her left hand? Why should she carry it so carefully? She did not need to refer to it in the interview. Does it not seem remarkable?”

“Well, sir, as you put it, perhaps it does.”

“I think I should like to sit quietly for a few minutes and think it out.” He seated himself upon upon the stone ledge of the bridge, and I could see his quick gray eyes darting their questioning glances in every direction. Suddenly he sprang up again and ran across to the opposite parapet, whipped his lens from his pocket, and began to examine the stonework.

“This is curious,” said he.

“Yes, sir, we saw the chip on the ledge. I expect it’s been done by some passer-by.”

The stonework was gray, but at this one point it showed white for a space not larger than a sixpence. When examined closely one could see that the surface was chipped as by a sharp blow.

“It took some violence to to do that,” said Holmes thoughtfully. With his cane he struck the ledge several times without leaving a mark. “Yes, it was a hard knock. In a curious place, too. It was not from above but from below, for you see that it is on the lower edge of the parapet.”

“But it is at least fifteen feet from the body.”

“Yes, it is fifteen feet from the body. It may have nothing to do with the matter, but it is a point worth noting. I do not think that we have anything more to learn here. There were no footsteps, you say?”

“The ground was iron hard, hard sir. There were no traces at all.”

“Then we can go. We will go up to the house first and look over these weapons of which you speak. Then we shall get on to Winchester, for I should desire to see Miss Dunbar before we go farther.”

Mr. Neil Gibson had not returned from town, but we saw in the house the neurotic Mr. Bates who had called upon us in the morning. He showed us with a sinister relish the formidable array of firearms of various shapes and sizes which his employer had accumulated in the course of an adventurous life.

"Don't you think, monsieur le 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 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."
