-this thing to-night?"

"May upset my whole view of the case. We must give the benefit of
every doubt, after all. We may, for instance, come back to the figure
on the porch: if it was a woman you saw that night through the window,
we might start with other premises. Or Mr. Innes' explanation may turn
us in a new direction. It is possible that he shot Arnold Armstrong as
a burglar and then fled, frightened at what he had done. In any case,
however, I feel confident that the body was here when he left. Mr.
Armstrong left the club ostensibly for a moonlight saunter, about half
after eleven o'clock. It was three when the shot was fired."

I leaned back bewildered. It seemed to me that the evening had been
full of significant happenings, had I only held the key. Had Gertrude
been the fugitive in the clothes chute? Who was the man on the drive
near the lodge, and whose gold-mounted dressing-bag had I seen in the

It was late when Mr. Jamieson finally got up to go. I went with him to

big clock on the stairs behind me was the only sound.

Then I was conscious that some one was running up the drive. In a
minute a woman darted into the area of light made by the open door, and
caught me by the arm. It was Rosie--Rosie in a state of collapse from
terror, and, not the least important, clutching one of my Coalport
plates and a silver spoon.

She stood staring into the darkness behind, still holding the plate. I
got her into the house and secured the plate; then I stood and looked
down at her where she crouched tremblingly against the doorway.

"Well," I asked, "didn't your young man enjoy his meal?"

She couldn't speak. She looked at the spoon she still held--I wasn't
so anxious about it: thank Heaven, it wouldn't chip--and then she
stared at me.

"I appreciate your desire to have everythi
