He went first to the tall French window in the middle of the wall that faced the door, and opening it, stepped out upon a small balcony with an iron railing. He looked down on a broad stretch of lawn that began immediately beneath him, separated from the house-wall only by a narrow flower-bed, and stretched away with an abrupt dip at the farther end, toward the orchard. The other window opened with a sash above the garden-entrance to the library. In the further inside corner of the room was a second door giving upon the passage; the door by which the maid was wont to come in, and her mistress to go out, in the morning.

Trent, seated on the bed, quickly sketched in his notebook a plan of the room and its neighbor. The bed stood in the angle between the communicating-door and the sash-window, its head against the wall dividing the room from Manderson's. Trent stared at the pillows; then he lay down with deliberation on the bed and looked through the open door into the adjoining room.

This observation taken, he rose again and proceeded to note on his plan that on either side of the bed was a small table with a cover. Upon that farthest from the door was a graceful electric-lamp standard of copper connected by a free wire with the wall. Trent looked at it thoughtfully, then at the switches connected with the other lights in the room. They were, as usual, on the wall just within the door, and some way out of his reach as he sat on the bed. He rose, and satisfied himself that the lights were all in order. Then he turned on his heel, walked quickly into Manderson's room, and rang the bell.

"I want your help again, Martin," he said, as the butler presented himself, upright and impassive, in the doorway. "I want you to prevail upon Mrs. Manderson's maid to grant me an interview."

"Certainly, sir," said Martin.

"What sort of a woman is she? Has she her wits about her?"

"She's French, sir," replied Martin succinctly; adding after a pause: "She has not been with us long, sir, but I have formed the impression that the young woman knows as much of the world as is good for her—since you ask me."

"You think butter might possibly melt in her mouth, do you?" said Trent. "Well, I am not afraid. I want to put some questions to her."

"I will send her up immediately, sir." The butler withdrew, and Trent wandered round the little room with his hands at his back. Sooner than he had expected, a small, neat figure in black appeared quietly before him.

The lady's maid, with her large brown eyes, had taken favorable notice of Trent from a window when he had crossed the lawn, and had been hoping desperately that the resolver of mysteries (whose reputation was as great below-stairs as elsewhere) would send for her. For one thing, she felt the need to make a scene; her nerves were overwrought. But her scenes were at a discount with the other domestics, and as for Mr. Murch, he had chilled her into self-control with his official manner. Trent, her glimpse of him had told her, had not the air of a policeman, and at a distance he had appeared sympathetique.
