I turned round to Mr. Howell. "It is Evelina, as I suspected."

"Yes, of course; I am only astonished that I could have taken her for Miss Frick when first I saw her. It must have been the costume which deceived me. Miss Frick has worn it all the spring."

"Yes, I know," I answered curtly. It was irritating always to have to return to Sigrid in this manner.

"Very well; on this occasion I also played the detective, Mr. Monk. I have privately found out from the other servants that Miss Frick had, that same afternoon, given the costume to Evelina. You see everything is quite clear in that respect."

"Will you allow the police to keep the photograph, Mr. Howell, and is there anything else you can tell us about the matter?" My manner was, perhaps, somewhat abrupt.

"Wait a little," he answered; "I hope you understand now the reason for the question which I put to you at the beginning of our conversation?"

"Yes; you would rather not appear as a witness, as far as I could understand."

"Exactly; and, as you yourself say, the person in question is already arrested, and the circumstantial evidence is so strong that my evidence cannot be of much importance one way or other. This being the case, would it not be possible for me to avoid appearing in court? and could you not consider what I have said as confidential, so that I might take the photograph and destroy it? Otherwise I shall appear very much in the light of a spy or a thief-catcher, Mr. Monk. Also, it would be most objectionable to me to have to testify against the unfortunate woman."

"Your sentiments do you all honour, Mr. Howell; but I cannot, all the same, prevent your being called as a witness. Neither can I, of course, keep your photograph against your will; but I must mention it in my report, and most earnestly request you to preserve it. What you have said to me in my office, with respect to a matter concerning which inquiries are now being conducted, I cannot, in my capacity as a police official, consider confidential."

"Well, Mr. Monk, I see it cannot be helped, and I ought, perhaps, to have denied all knowledge of the matter. But you can, at any rate, bear evidence that I appear most reluctantly; I would like both the unhappy girl and the Frick family to understand this."
