“As to the arrow and its means of secret transfer from one side of the building to the other in the face of a large crowd, let me direct your attention to this little strip of folded silk.  You have seen it before.  Surely, I am quite justified in asking whether indeed you have not handled it both before and after the lamentable occurrence we are discussing?”

“I see it for the first time,” came from lips so stiff that the words were with difficulty articulated.  “What is its purpose?” he asked after a short pause.

“I hardly think it necessary to tell you,” came in chilling response from the now thoroughly disenchanted official.  “It looks like a loop, and notwithstanding your assertion that you see it now for the first time, we have ample evidence that it was once attached to the coat you wore on that fatal day and later carefully severed from it and dropped on the museum floor.”

The District Attorney waited, they all waited with eyes on the subject of this attack, for some token of shame or indignation at this scarcely veiled insinuation.  But beyond a certain stillness of expression, still further masking a countenance naturally cold and irresponsive, no hint was given that any effect had been produced upon him by these words.  The coal before it falls apart into ash holds itself intact though its heart of flame has departed; so he—­or such was Mr. Gryce’s thought as he waited for the District Attorney’s next move.

“Gentlemen, I have shown patience up till now, because I saw that you had something on your minds which it might be better for you and possibly for me to be rid of.  This affair of Miss Willett’s death is, as all must acknowledge, baffling enough to strain even to the point of folly any effort made to explain it.  I had sympathy with your difficulties, and have still enough of that sympathy left, not to express too much indignation at what you are pleased to call your suspicions.  I will merely halt for the moment your attempts in my direction, by asking, what have you or anybody else ever seen in me to think I would practise my old-time skill on a young and beautiful stranger enjoying herself in a place so dear to my heart as the museum of which I have been
