"Indeed, my friend, it is, and I am glad that you have come in person to acquaint me with your anxiety in my behalf. This I will more thoroughly explain to you later. For the present, I may say that I am glad to have you here as a possible witness, in case murder, or any other crime, should be attempted."
"What other crime do you anticipate as possible? Surely not theft?"
"Why not?"
"What! Steal that opal from you, while you are present to see the deed committed? That is a joke." Mr. Barnes laughed heartily.
"Your laugh is a compliment," said Mr. Mitchel. "Yet that is exactly what I most anticipate—theft. I am not sure that it may not be undertaken before my very eyes. Especially as the thief did not hesitate at a table filled with men and women. Sh! He is here."
The electric street-door bell had sounded. Mr. Mitchel arose, and spoke hurriedly in a low tone.
"That is probably Mr. Livingstone come to sell his opal, or to steal mine. We shall see. Especially I desire that you should see. Consequently I have arranged matters in advance. Slip behind this bookcase, which I have placed across the corner that you may have room to breathe. The books on the top shelf have been removed, and the tinted glass of the doors will not obstruct your view. From behind you will be able to see through quite readily."
"Why, you seem to have expected me," said Mr. Barnes, getting into the hiding-place.
"Yes, I expected you," said Mr. Mitchel, vouchsafing
no further explanation. "Remember now,
Mr. Barnes, you are not to interfere, whatever happens, unless I call you. All I ask is that you use your eyes, and that good eyes will be required be sure, or I never should have arranged to have an extra pair to aid me on this occasion."
A moment later Williams announced Mr. Livingstone.
