"Why, that's odd," said Cram. "Better bolt it now, or all the cattle along the levee will be in there. You can't lock out the water, though. Who had the key besides Mr. Lascelles or Madame?" "Nobody, sare; but there is muddy foots all over the piazza." "The devil! I'll have to look in for a moment." A nod to Pierce brought him too from the saddle, and the officers handed their reins to the orderlies. Then together they entered the gate and strode up the white shell walk, looking curiously about them through the dripping shrubbery. Again that dismal howl was raised, and Pierce, stopping with impatient exclamation, tore half a brick from the yielding border of the walk and sent it hurtling through the trees. With his tail between his legs, the brute darted from behind a sheltering bush, scurried away around the corner of the house, glancing fearfully back, then, halting at safe distance, squatted on his haunches and lifted up his mournful voice again. "Whose dog is that?" demanded Cram. "M'sieu' Philippe's: he not now here. He is de brudder to Monsieur." At the steps the captain bent and closely examined them and the floor of the low veranda to which they led. Both were disfigured with muddy footprints. Pierce would have gone still further in the investigation, but his senior held up a warning hand. "Two men have been here," he muttered. "They have tried the door and tried the blinds.--Where did you sleep last night, boy?" and with the words he turned suddenly on the negro. "Did you hear no sound?" "No, sare. I sleep in my bed,--'way back. No, I hear noting,--noting." And now the negro's face was twitching, his eyes staring. Something in the soldier's stern voice told him that there was tragedy in the air. "If this door is locked, go round and open it from within," said Cram, briefly. Then, as Alphonse disappeared around the north side, he stepped back to the shell walk and followed one of its branches around the other. An instant later Pierce heard him call. Hastening in his wake, the youngster came upon his captain standing under a window, one of whose blinds was hanging partly open, water standing in pools all around him. "Look here," was all he said, and pointed upward. The sill was above the level of their heads, but both could see that the sash was raised. All was darkness within. "Come with me," was Cram's next order, and the lieutenant followed. Alphonse was unlocking the front door, and now threw it open. Cram strode into the wide hall-way straight to a door of the east side. It was locked. "Open this, Alphonse," he said. "I have not the key. It is ever with M'sieu' Lascelles. It is his library."
