and hats were neatly arranged in the closet, but nowhere could he find a dressing gown or a pair of bedroom slippers. Clara, moreover, could not recall having seen the housekeeper wear any hat or clothes other than those in the closet. If McDonald's daughter had fled from the house in slippers and dressing gown it was strange she hadn't been heard of long ago. It became increasingly clear to him that the woman remained hidden in the house. It should be easy enough to find her. He would search every corner for the one whose brain, he was now convinced, held the solution of the mystery. But on the lower floor he found no trace. He paused in the lower hall, intending to ring for McDonald to guide him through the rest of his task.
All at once his hand which he had raised to the bell hesitated. He braced himself against the wall. Through the heavy atmosphere a stifled groan had reached him, followed by a difficult dragging sound. But as he sprang up the stairs he knew he hadn't heard the cause of Clara's fright, for the groan had sufficiently defined itself as having come from a man.
In the upper hall there was no light beyond the glow sifting through the stair well. It was enough to show Garth a dark form huddled at the foot of the stairs leading to the third story. He ran over and stooped.
"McDonald! What's the matter? Are you hurt?"
The silence of the house was heavier, more secretive than before.
