The Inspector's speech might seem cold-hearted, but Brunt was a practical man, and he was truly glad for himself that in addition to finding the murderer he did not also have to recover a fortune of rare jewels. "Now," he went on, "as to the maid, Estelle. I have talked with her, but she is so hysterical and her stories so contradictory, that I am inclined to the opinion that she has some sort of guilty knowledge or at least suspicion of the intruder. The man was stocking-footed, and it is a pity, Miss Stuart, that you erased that footprint on the floor! But it would have been of doubtful use, I dare say. We have found faint tracks of the powder on the steps of the staircase, and though the last ones are almost indiscernible they seem to lead through the butler's pantry, and to an exit by that window. But the window was found fastened this morning, so, if it was used as a means for the burglar's getaway, it must have been fastened afterward by some person inside. Could this person have been the maid, Estelle?" "Sure it could!" exclaimed Haviland, who was an interested listener. "That girl is a sly one! I caught her this morning, trying to take away that glass of milk. I told her to let it alone." "Why?" asked the Inspector. "Because I thought if she wanted to get it away, there must be some reason for her to want it! What was it?" "Nonsense!" and Anita looked scornfully at Gray; "naturally, Estelle would do up the rooms, and would, of course, remove the remains of Miss Lucy's night luncheon." "But that's just it!" said Haviland, triumphantly: "she didn't take the plate that had had sandwiches on it! If she had, I should have thought nothing of it. But she took the glass of milk, in a furtive, stealthy way, that made me look at her. She turned red, and trembled, and I told her to set the glass down. She pretended not to hear, so I told her again. Then she obeyed. But she glared at me like a tigress." "Oh, rubbish!" said Anita. "She was annoyed at being interfered with in her work, and perhaps fearful of being censured." "All right," said Haviland, "then there's no harm done. If that girl is entirely innocent, what I said won't hurt her. But she looked to me as if on a secret errand and a desperate one." "What puzzles me is," mused the Inspector, "why she persists in saying that she left the tray in good order in the room,--though it was discovered an hour later, upset,--when we know that Miss Carrington had been dead since, at least, two or three o'clock." "Look here, Inspector," and Haviland frowned, "if the murder was committed at two or three o'clock, how is it that Mrs. Frothingham saw the intruder escaping at four or later?" "There is a discrepancy there," admitted Brunt, "but it may be explained away. The doctors cannot be sure until the autopsy is completed of the exact hour of death, and, too, the lady next door may have made an error in time."
