"Yes, a shutter, and I knew well that every shutter on my house was either shut tight or locked open. I look to that every night, as soon as it's lamp-lighting time; them downstairs I shut, them upstairs I open, sometimes. I knew where that slammin' shutter was by the sound, and it set me to dressing quick. I had opened the shutters on Mr. Brierly's windows that very afternoon, thinking the rooms would not seem quite so dreary and lonesome when his brother came to look through 'em and they was locked open, I knew well! All the same, it was them shutters, or one of 'em, that was clattering then, and I knew it."

"Were you alone in the house, you and your little girl?" asked Ferrars.

"All alone, yes, sir; and I took Nellie with me and went out into the hall——"

"You mean downstairs?"

"Yes, sir. We sleep downstairs. Now, I thought I had seen that everything was right when Mr. Jones and Mary was with me, but when we went into that hall—Doctor—" turning again toward that gentlemen, for she had addressed her later remarks to Ferrars,—"I guess you may remember a shelf just at the foot of the stairs. It's right behind the door, when it stands open, and that's why we hadn't seen it, or I hadn't before. Well, I always set the lamp for Mr. Brierly's room—his bedroom lamp, that is—on that shelf for him every morning, as soon as it had been filled for the night's burning; and the morning he was killed I had put it there as usual, and it had been there ever since. It was there when Mr. Brierly and you two gentlemen called, after the inquest."

A queer little sound escaped the detective's throat, and again he checked the doctor's impatience with that slight movement of the head.

"I don't call myself brave," the woman went on, "but I caught Nellie by the hand—I was carrying my bedroom lamp—and ran up the stairs and straight to Mr. Brierly's door. I don't know what made me do it, but I stooped down to look through the keyhole, and there in the door was the very key I had given to that boy to take to Mr. Brierly's brother."

"What did you do?" asked the doctor, breathlessly.

"I set down my lamp very softly, told Nellie in a whisper not to make a noise, and then very carefully tried the key. It turned in the lock. I didn't dare go in, but I locked the door, left the key in it, and went downstairs and out at the front door. I went around the house and stood under the window of that room. The side window shutter that I had fastened back was swinging loose. I went back to the sitting-room, locking the front door and the doors from the hall into the front room and sitting-room, taking out the key of the front door, and leaving the other keys in the locks, on my side. Then I lit the big lamp, pulled down the curtains, fixed the side door so I could open it quick, and set the big dinner bell close by it. I made Nellie lie down on the lounge with her clothes on, and there I sat till morning. Before daylight I went into the kitchen and moved about very softly to get myself a cup of coffee, and a bite of breakfast for Nellie. I had been careful not to let her see how I was scared, and she went sound asleep right away. As soon as I thought you would be up I awoke my little girl, and left her sitting upon the side stoop, while I came here to you. Mr. Brierly's brother ought to be first to enter that room, and—if there was anyone there last night—they're there yet."

"What room is that which I ought to enter, Mrs. Fry?" said a voice behind them, and turning, all together, they saw Robert Brierly standing at the edge of the porch where it joined the wall of the doctor's room.
