"Since you do not know him, Mrs. Altonstall, let us not discuss him. Will you tell me how you lost possession of this key, since it is yours?"
"I gave it to my lawyer, Mr. Leroy," she replied. "It was necessary that he should get some of my papers from the Safe Deposit Company, and it has been arranged that he shall have access to my box on presentation of my key. I am a widow, Mr. Landon, and as I have various financial interests, it is necessary for me frequently to employ the services of a lawyer. Mr. Leroy attends to all such affairs for me."
"Do you mean Mr. Graham Leroy?" I asked, very gravely, for the introduction of his name stirred up all sorts of conjectures.
"Yes," she replied, "he is an able lawyer, as well as a kind friend."
"I'm acquainted with Mr. Leroy," I responded, "and I quite agree with your estimate of him. When did you give him the key, Mrs. Altonstall?"
"About four or five days ago; last Saturday, to be exact. There was no immediate haste about my papers, he was to attend to the matter at his convenience. May I ask where the key was found?"
I disliked extremely to rehearse the details of the case, and I knew it was in no way necessary. Of course the key belonged to this lady; aside from her own word, the bank had told me so. But her question must be answered.
"It was found in the apartment of Mr. Robert Pembroke," I said; but immediately added, as she looked slightly startled, "I think, however, it is a matter of easy explanation. Graham Leroy is also Mr. Pembroke's lawyer, and he must have dropped the key there while calling on Mr. Pembroke."
"Unpardonable carelessness," she said, and I saw that the sweet placid face could assume an expression of indignation upon occasion.
"That, madam, you must say to Mr. Leroy. I am sorry to have troubled you in the matter, and I thank you for your courtesy to me."
