I was so dumfounded by this last assertion, I did not attempt to reply. Fortunately, he misinterpreted my silence and the "stony glare" with which it was accompanied. "I know that it must seem to you altogether too bad, to be tripped up at the moment of your anticipated triumph. But if apologies will suffice to express our sense of presumption, then I pray you to accept them, Miss Butterworth, both on my own part and on that of the Superintendent of Police." I did not understand in the least what he was talking about, but I recognized the sarcasm of his final expression, and had spirit enough to reply: "The subject is too important for any more nonsense. Whereabouts in Franklin Van Burnam's desk were these rings found, and how do you know that his brother did not put them there?" "Your ignorance is refreshing, Miss Butterworth. If you will ask a certain young girl dressed in gray, upon what object connected with Mr. Van Burnam's desk she laid her hands yesterday morning, you will have an answer to your first question. The second one is still more easily answered. Mr. Howard Van Burnam did not conceal the rings in the Duane Street office for the reason that he has not been in that office since his wife was killed. Regarding this fact we are as well advised as yourself. Now you change color, Miss Butterworth. But there is no necessity. For an amateur you have made less trouble and fewer mistakes than were to be expected." Worse and worse! He was patronizing me now, and for results I had done nothing to bring about. I surveyed him in absolute amazement. Was he amusing himself with me, or was he himself deceived as to the nature and trend of my late investigations. This was a question to settle, and at once; and as duplicity had hitherto proved my best weapon in dealing with Mr. Gryce, I concluded to resort to it in this emergency. Clearing my brow, I regarded with a more amenable air the little Hungarian vase he had taken up on entering the room, and into which he had been talking ever since he thought it worth while to compliment its owner. "I do not wish," said I, "to be published to the world as the discoverer of Franklin Van Burnam's guilt. But I do want credit with the police, if only because one of their number has chosen to look upon my efforts with disdain. I mean you, Mr. Gryce; so, if you are in earnest"--he smiled at the vase most genially--"I will accept your apologies just so far as you honor me with your confidence. I know you are anxious to hear what evidence I have collected, or you would not be wasting time on me this busy morning." "Shrewd!" was the short ejaculation he shot into the mouth of the vase he was handling.
