"And you are satisfied that this lady, a refined, delicate person in the best society, of the highest character,-believe me, I know that to be the case,-whom you yet suspect of an atrocious crime, was the only female in the car?"

"Obviously. Who else? What other woman could possibly have been in the car? No one got in at Laroche; the train never stopped till it reached Paris."

"On that last point at least you are quite mistaken, I assure you. Why not upon the other also?"

"The train stopped?" interjected the detective. "Why has no one told us that?"

"Possibly because you never asked. But it is nevertheless the fact. Verify it. Every one will tell you the same."

The detective himself hurried to the door and called in the porter. He was within his rights, of course, but the action showed distrust, at which the General only smiled, but he laughed outright when the still stupid and half-dazed porter, of course, corroborated the statement at once.

"At whose instance was the train pulled up?" asked the detective, and the Judge nodded his head approvingly.

To know that would fix fresh suspicion.

But the porter could not answer the question. Some one had rung the alarm-bell-so at least the conductor had declared; otherwise they should not have stopped. Yet he, the porter, had not done so, nor did any passenger come forward to admit giving the signal. But there had been a halt. Yes, assuredly.

"This is a new light," the Judge confessed. "Do you draw any conclusion from it?" he went on to ask the General.

"That is surely your business. I have only elicited the fact to disprove your theory. But if you wish, I will tell you how it strikes me."

The Judge bowed assent.

"The bare fact that the train was halted would mean little. That would be the natural act of a timid or excitable person involved indirectly in such a catastrophe. But to disavow the act starts suspicion. The fair inference is that there was some reason, an unavoidable reason, for halting the train."

"And that reason would be-"

"You must see it without my assistance, surely! Why, what else but to afford some one an opportunity to leave the car."

"But how could that be? You would have seen that person, some of you, especially at such a critical time. The aisle would be full of people, both exits were thus practically overlooked."

"My idea is-it is only an idea, understand-that the person had already left the car-that is to say, the interior of the car."

"Escaped how? Where? What do you mean?"

"Escaped through the open window of the compartment where you found the murdered man."

"You noticed the open window, then?" quickly asked the detective. "When was that?"

"Directly I entered the compartment at the first alarm. It occurred to me at once that some one might have gone through it."

"But no woman could have done it. To climb out of an express train going at top speed would be an impossible feat for a woman," said the detective, doggedly.

"Why, in God's name, do you still harp upon the woman? Why should it be a woman more than a man?"

"Because"-it was the Judge who spoke, but he paused a moment in deference to a gesture of protest from M. Flocon. The little detective was much concerned at the utter want of reticence displayed by his colleague.

"Because," went on the Judge with decision-"because this was found in the compartment;" and he held out the piece of lace and the scrap of beading for the General's inspection, adding quickly, "You have seen these, or one of them, or something like them before. I am sure of it; I call upon you; I demand-no, I appeal to your sense of honour, Sir Collingham. Tell me, please, exactly what you know."

CHAPTER X

The General sat for a time staring hard at the bit of torn lace and the broken beads. Then he spoke out firmly: "It is my duty to withhold nothing. It is not the lace. That I could not swear to; for me-and probably for most men-two pieces of lace are very much the same. But I think I have seen these beads, or something exactly like them, before."

"Where? When?"

"They formed part of the trimming of a mantle worn by the Contessa di Castagneto."

"Ah!" it was the same interjection uttered simultaneously by the three Frenchmen, but each had a very different note; in the Judge it was deep interest, in the detective triumph, in the Commissary indignation, as when he caught a criminal red-handed.

"Did she wear it on the journey?" continued the Judge.

"As to that I cannot say."

"Come, come, General, you were with her constantly; you must be able to tell us. We insist on being told." This fiercely, from the now jubilant M. Flocon.

"I repeat that I cannot say. To the best of my recollection, the

Countess wore a long travelling cloak-an ulster, as we call them. The jacket with those bead ornaments may have been underneath. But if I have seen them,-as I believe I have,-it was not during this journey."

Here the Judge whispered to M. Flocon, "The searcher did not discover any second mantle."

"How do we know the woman examined thoroughly?" he replied. "Here, at least, is direct evidence as to the beads. At last the net is drawing round this fine Countess."

"Well, at any rate," said the detective aloud, returning to the General, "these beads were found in the compartment of the murdered man. I should like that explained, please."

"By me? How can I explain it? And the fact does not bear upon what we were considering, as to whether any one had left the car."

"Why not?"

"The Countess, as we know, never left the car. As to her entering this particular compartment,-at any previous time,-it is highly improbable. Indeed, it is rather insulting her to suggest it."

"She and this Quadling were close friends."

"So you say. On what evidence I do not know, but I dispute it."

"Then how could the beads get there? They were her property, worn by her."

"Once, I admit, but not necessarily on this journey. Suppose she had given the mantle away-to her maid, for instance; I believe ladies often pass on their things to their maids."

"It is all pure presumption, a mere theory. This maid-she has not as yet been imported into the discussion."

"Then I would suggest that you do so without delay. She is to my mind a-well, rather a curious person."

"You know her-spoke to her?"

"I know her, in a way. I had seen her in the Via Margutta, and I nodded to her when she came first into the car."

"And on the journey-you spoke to her frequently?"

"I? Oh, dear, no, not at all. I noticed her, certainly; I could not help it, and perhaps I ought to tell her mistress. She seemed to make friends a little too readily with people."

"As for instance-?"

"With the porter to begin with. I saw them together at Laroche, in the buffet at the bar; and that Italian, the man who was in here before me; indeed, with the murdered man. She seemed to know them all."

"Do you imply that the maid might be of use in this inquiry?"

"Most assuredly I do. As I tell you, she was constantly in and out of the car, and more or less intimate with several of the passengers."

"Including her mistress, the Countess," put in M. Flocon.

The General laughed pleasantly. "Most ladies are, I presume, on intimate terms with their maids. They say no man is a hero to his valet. It is the same, I suppose, with the other sex."

"So intimate," went on the little detective, with much malicious emphasis, "that now the maid has disappeared lest she might be asked inconvenient questions about her mistress."

"Disappeared? You are sure?"

"She cannot be found, that is all we know."

"It is as I thought, then. She it was who left the car!" cried Sir Charles, with so much vehemence that the officials were startled out of their dignified reserve, and shouted back almost in a breath: "Explain yourself. Quick, quick. What in God's name do you mean?"
