"The what?" asked de Bohun.

"The probing," answered his guest briefly. "That's a longer job, 'specially as I noticed that there's stone floors about. Now 'ere's another matter. Look at this carpet. That's Aubusson, that is. Ah, I notice everything! Aubusson—that's what it is."

"Mr. Collop," broke in Marjorie, in her suffering....

"Now, Miss," said Mr. Collop with command, "don't you interrupt me. Let me put the necessaries before you. When you get all this done, sir, what are you to do, then? What are you to do next? Why, I'll tell you. You'll have all the shutters shut: I noticed you 'ad shutters: and those curtains pulled. Then you'll put what they call Marlin's New Irridiant up. That's the light we work by. And I'll tell you for why. You 'ave plain electrics in the room and they casts shadows. Don't they, Miss?" he appealed to his hostess. But before she could agree, he went on, like a mighty river in flood:

"Now, casting shadows, you might miss a small object. That's how objects do get missed. You've got to think of these things. Artificial light that is distributed high and in the corners...."

The Home Secretary could bear no more. "Yes, yes, yes," he said. "Where does one get the stuff?"

"You'll see!" said Mr. Collop tartly, but with pardonable pride. "It's expensive, mind you," he added honestly. "But you got to do this job well or not at all."

"But, Mr. Collop," said poor Marjorie, who could hardly bear another moment, "before all this expense couldn't we ..."

"No, Miss," said the redoubtable Collop, shaking his head firmly. "Not to be thought on! I wouldn't undertake the responsibility, I wouldn't. And mind you, this ain't the first job of the sort I've tackled; not by thousands it ain't." (An exaggeration—due, I am afraid, to the whiskey.) "I wouldn't undertake the responsibility! I'll put no man under a cloud till I've made certain that it's not lost and hiding of its own. If it's not found, why then it'll be time to begin."

It was Marjorie who found the decision to break off the battle. She got up suddenly.
