“It is very strange,” he said, finally.  “If the cabinet was still at Paris, one would think it would have been discovered before my client made inquiry about it.”

“There are a good many things which are strange about this whole matter,” I supplemented.

“Would you have any objection to my client seeing this cabinet, Mr. Lester?”

It was my turn to hesitate.

“Mr. Hornblower,” I said, finally, “I will be frank with you.  There is a certain mystery surrounding this cabinet which we have not been able to solve.  I suppose you have read of the mysterious deaths of Mr. Vantine and of an unknown Frenchman, both in the same room at the Vantine house, and both apparently from the same cause?”

He nodded.

“Do you mean that this cabinet is connected with them in any way?” he asked quickly.

“We believe so; though as yet we have been able to prove absolutely nothing.  But we are guarding the cabinet very closely.  I should not object to your client seeing it, but I could not permit her to touch it—­not, at least, without knowing why she wished to do so.  You will remember that you have told me nothing of why she is interested in it.”

“I am quite ready to tell you the story, Mr. Lester,” he said.  “It is only fair that I should do so.  After you have heard it, if you agree, we will take Madame X. to see the cabinet.”

He settled back in his chair, and his face became more grave.

“My client,” he began, “is a member of a prominent American family—­a most prominent family.  Three years ago, she married a French nobleman.  You can, perhaps, guess her name, but I should prefer that neither of us utter it.”

I nodded my agreement.

“This nobleman has been both prodigal and unfaithful.  He has scattered my client’s fortune with both hands.  He has flaunted his mistresses in her face.  He has even tried to compel her to receive one of them.  I am free to confess that I consider her a fool not to have left him long ago.  At last her trustees interfered, for her father had been wise enough to place a portion of her fortune in trust.  They paid her husband’s debts, placed him on an allowance, and notified his creditors that his debts would not be paid again.”

I had by this time, of course, guessed the name of his client, since these details had long been a matter of public notoriety, and, I need hardly say, listened to the story with a heightened interest.

“The allowance is a princely one,” Mr. Hornblower continued, “but it does not suffice Monsieur X. No allowance would suffice him—­the more money he had, the more ways he would find of spending it.  So he has become a thief.  He has taken to selling the objects of art with which his residences are filled, and which are really the property of my client, since they were purchased with her money.  About two weeks ago, my client returned
