"Madam, you have supplied the one link necessary to the establishment of this theory. Allow me to felicitate you upon it. But whatever our satisfaction may be from a professional standpoint, we cannot but feel the unhappy nature of the responsibility incurred by these discoveries. If this seemingly respectable family stooped to such subterfuge, going to the length of winding rags around the wheels of their lumbering old coach to make it noiseless, and even tying up their horse's feet for this same purpose, they must have had a motive dark enough to warrant your worst suspicions. And William was not the only one involved. Simsbury, at least, had a hand in it, nor does it look as if the girls were as innocent as we would like to consider them."
"I cannot stop to consider the girls," I declared. "I can no longer consider the girls."
"Nor I," he gloomily assented. "Our duty requires us to sift this matter, and it shall be sifted. We must first find if any child alighted from the cars at the Mountain Station on that especial night, or, what is more probable, from the little station at C., five miles farther back in the mountains."
"And—" I urged, seeing that he had still something to say.
"We must make sure who lies buried under the floor of the room you call the Flower Parlor. You may expect me at the Knollys house some time to-day. I shall come quietly, but in my own proper person. You are not to know me, and, unless you desire it, need not appear in the matter."
"I do not desire it."
"Then good-morning, Miss Butterworth. My respect for your abilities has risen even higher than before. We part in a similar frame of mind for once."
And this he expected me to regard as a compliment.
