his coffee cup, "it must be that it is so; but who would believe it?"
I sighed in vexation. His habit of musing aloud but refusing to tell the trend of his thoughts while lie arranged the factors of a case upon his mental chess-board was one which always annoyed me, but nothing I had been able to do had swerved him from his custom of withholding all information until he reached the climax of the mystery. "Non, non," he replied when I pressed him to take me into his confidence, "the less I speak, the less danger I run of showing myself to be one great fool, my friend. Let me reason this business in my own way, I beseech you." And there the matter rested.
Toward midnight he rose impatiently and motioned toward the door. "Let us go," he suggested. "It will be an hour or more before we reach our destination, and that should be the proper time for us to see what I fear we shall behold, Friend Trowbridge."
We drove across country to Springville through the early autumn night in silence, turned in at the orphanage gates and parked before the administration building, where Superintendent Gervaise maintained his living quarters.
"Monsieur," de Grandin called softly as he rapped gently on the superintendent's door, "it is I, Jules de Grandin. For all the wrong I have done you I humbly apologize, and now I would that you give me assistance."
Blinking with mingled sleep and surprize, the little, gray-haired official let us into his rooms and smiled rather fatuously at us. "What, is it you'd like me to do for you, Dr. de Grandin?" he asked.
"I would that you guide us to the sleeping apartments of Mère Martin. Are they in this building?"
"No," Gervaise replied wonderingly. "Mother Martin has a cottage of her own over at the south end of the grounds. She likes the privacy of a separate house, and we"
"Précisément," the Frenchman agreed, nodding vigorously. "I well understand her love of privacy, I fear. Come, let us go. You will show us the way?"
Mother Martin's cottage stood by the southern wall of the orphanage compound. It was a neat little building of the semi-bungalow type, constructed of red brick, and furnished with a low, wide porch of white-painted wood. Only the chirping of a cricket in the long grass and the long-drawn, melancholy call of a crow in the near-by poplars broke the silence of the starlit night as we walked noiselessly up the brick path leading to the cottage door. Gervaise was about to raise the polished brass knocker which adorned the white panels when de Grandin grasped his arm, enjoining silence.
Quietly as a shadow the little Frenchman crept from one of the wide, shutterless front windows to the other, looking intently into the darkened interior of the house, then, with upraised finger warning us to caution, he tiptoed from the porch and began making a circuit of the house, pausing to peer through each window as he passed it.
At the rear of the cottage was a one-story addition which evidently housed the kitchen, and here the blinds were tightly drawn, though beneath their lower edges there crept a faint, narrow band of lamplight.
"Ah—bien!" the Frenchman breathed, flattening his aquiline nose against the window-pane as though he would look through the shrouding curtain by virtue of the very intensity of his gaze.
A moment we stood there in the darkness, de Grandin's little waxed mustache twitching at the ends like the whiskers of an alert tom-cat, Gervaise and I in total bewilderment,
