"She is dead," said Musard gently. "This is a terrible business, and our first duty is to try and capture the monster who committed this foul crime."

They stood there in silence for a moment, looking earnestly at one another. Outside, somewhere in the woodland, there sounded the haunting gush of a night-bird's song, shivering through the quietness like a silver bell. The sweet note finished in a frightened squawk, and was followed by the cry of an owl. The song had betrayed the singer.

Musard turned away from Miss Heredith, and walked restlessly around the bedroom, scanning the heavy pieces of furniture and the faded hangings, and peering into every nook and corner, as if seeking for the murderer's place of concealment. A roomy old wardrobe near the window attracted his eye, and he stopped in front of it and flung its doors open. It contained some articles of the dead girl's apparel—costumes and frocks—hanging on hooks.

His eye wandered to the window, shrouded in the heavy folds of the damask curtains. He walked over to it, and drew the curtains aside. The bottom half of the window was wide open.

Miss Heredith, who was following his movements closely, gave vent to a faint cry of surprise.

"The window!" she exclaimed.

Musard looked round inquiringly.

"The window—what of it?" he asked.

"It was closed when I came in here before dinner to see Violet."

"You are quite sure of that?"
