"By Monsieur X.?" I asked quickly.

"By Monsieur X.," said Mr. Hornblower, and sat regarding me, his lips pursed, as an indication, perhaps, that he would say no more.

But there was no necessity that he should. I knew enough of French law and of French habits of thought to realise that if those letters ever came into possession of Monsieur X., the game would be entirely in his hands. His wife would be absolutely at his mercy. And the thought flashed through my mind that perhaps in some way he had learned of the existence of the letters, and was trying desperately to get them. That thought was enough to swing the balance in his wife's favour.

"I am sure," I said, "that Mr. Vantine would instantly have consented to your client opening the drawer and taking out the letters. And, as his executor, I also consent, for, whoever may own the cabinet, the letters are the property of Madame X. All this providing, of course, that this should prove to be the right cabinet. But I must warn you, Mr. Hornblower, that I believe two men have already been killed trying to open that drawer," and I told him, while he sat there staring in profound amazement, of my theory in regard to the death of Philip Vantine and of the unknown Frenchman. "I am inclined to think," I concluded, "that Vantine blundered upon the drawer while examining the cabinet; but there is no doubt that the other man knew of the drawer, and also, presumably, of its contents."

"Well!" exclaimed my companion. "I have listened to many astonishing stories in my life, but never one to equal this. And you know nothing of this Frenchman?"

"Nothing except that he came from Havre on _La Touraine_ last Thursday, and drove from the dock direct to Vantine's house."

"My client also came on _La Touraine_--but that, no doubt, was a mere coincidence."

"That may be," I agreed, "but it is scarcely a coincidence that both he and your client were after the contents of that drawer."

"You mean...."

"I mean that the mysterious Frenchman may very possibly have been an emissary of Monsieur X. Madame may have betrayed the secret to him in an unguarded moment."

Mr. Hornblower rose abruptly. He was evidently much disturbed.

"You may be right," he agreed. "I will communicate with my client at once. I take it that she has your permission to see the cabinet; and, if it proves to be the right one, that she may open the drawer and remove the letters."

"If she cares to take the risk," I a.s.sented.

"Very well; I will call you as soon as I have seen her," he said. "In any event, I thank you for your courtesy," and he left the office.

He must have driven straight to her family residence on the Avenue; or perhaps she was awaiting him at his office; at any rate, he called me up inside the half hour.

"My client would like to see the cabinet at once," he said. "She is in a very nervous condition; especially since she learned that some one else has tried to open the drawer. When will it be convenient for you to go with us?"

"I can go at once," I said.

"Then we will drive around for you. We should be there in fifteen or twenty minutes."

"Very well," I said, "I'll be ready. I shall, of course, want to take a witness with me."

"That is quite proper," a.s.sented Mr. Hornblower. "We can have no objection to that. In twenty minutes, then."

I got the _Record_ office as soon as I could, but G.o.dfrey was not there. He did not come on usually, some one said, until the middle of the afternoon. I rang his rooms, but there was no reply. Finally I called up the Vantine house.

"Parks," I said, "I am bringing up some people to look at that cabinet. It might be just as well to get that cot out of the way and have all the lights going?"

"The lights are already going, sir," he said.

"Already going? What do you mean?"

"Mr. G.o.dfrey has been here for quite a while, sir, fooling with that cabinet thing."

"He has!" and then I reflected that I ought to have guessed his whereabouts. "Tell him, Parks, that I am bringing some people up to see the cabinet, and that I should like him to stay there and be a witness of the proceedings."

"Very well, sir," a.s.sented Parks.

"Everything quiet?"

"Oh, yes, sir; there was two policemen outside all night, and Rogers and me inside."

"Mr. Hornblower's carriage is below, sir," announced the office-boy, opening the door.

"All right," I said. "We are coming right up, Parks. Good-bye," and I hung up and slipped into my coat.

Then, as I took down my hat, a sudden thought struck me.

If the unknown Frenchman was indeed an emissary of Monsieur X., Madame might be acquainted with him. It was a long shot, but worth trying! I stepped to my desk, took out the photograph which G.o.dfrey had given me, and slipped it into my pocket. Then I hurried out to the elevator.

CHAPTER XIV

THE VEILED LADY

There were three persons in the carriage. Mr. Hornblower sat with his back to the horses, and two women were on the opposite seat. Both were dressed in black and heavily veiled, but there was about them the indefinable distinction of mistress and maid. It would be difficult to tell precisely in what the distinction consisted, but it was there. Mr. Hornblower glanced behind me as I entered.

"You spoke of a witness," he said.

"He is at the Vantine house," I explained, and sat down beside him.

"This is Mr. Lester," he said, and the veiled lady opposite him, whom I had known at once to be the mistress, inclined her head a little.

Those were the only words spoken. The carriage rolled out to Broadway and then turned northward, making such progress as was possible along that crowded thoroughfare. I glanced from time to time at the women opposite, and was struck by the contrast in their behaviour. One sat quite still, her hands in her lap, her head bent, admirably self-contained; the other was restless and uneasy, unable to control a nervous twitching of the fingers. I wondered why the maid should seem more upset than her mistress, and decided finally that her uneasiness was merely lack of breeding. But the contrast interested me.

At Tenth Street, the carriage turned westward again, skirted Washington Square, turned into the Avenue, and stopped before the Vantine house. Mr. Hornblower a.s.sisted the women to alight, and I led the way up the steps. But as we reached the top and came upon the funeral wreath on the door, the veiled lady stopped with a little exclamation.

"I did not know," she said, quickly. "Perhaps, after all, we would better wait. I did not realise...."

"There are no relatives to be hurt, madame," I interrupted. "As for the dead man, what can it matter to him?" and I rang the bell.

Parks opened the door, and, nodding to him, I led the way along the hall and into the ante-room. G.o.dfrey was awaiting us there, and I saw the flame of interest which leaped into his eyes, as Mr. Hornblower and the two veiled women entered.

"This is my witness," I said to the former. "Mr. G.o.dfrey--Mr.

Hornblower."

G.o.dfrey bowed, and Hornblower regarded him with a good-humoured smile.

"If I were not sure of Mr. G.o.dfrey's discretion," he said, "I should object. But I have tested it before this, and know that it can be relied upon."

"There is only one person to whom I yield precedence in the matter of discretion," rejoined G.o.dfrey, smiling back at him, "and that is Mr.
