Now Carmel was down in Part II to dance the Pastorale, and she ran into the house to change her Greek chiton for the dress of a Sicilian peasant. She went through the veranda and the open French window, and straight upstairs to her bedroom. She had brought nobody with her, because, for one thing, she needed no help, and for another she was hot and excited, and felt that she would like a few minutes' rest quite to herself. There was no great hurry, so she leisurely put on the pretty scarlet and white-striped skirt, the velvet apron, the white bodice and laced corsage, clasped the necklace round her throat, and twisted the gay silk handkerchief as a head-dress on her dark hair. It was a prettier and more effective costume even than the Greek one. There was an Eastern variety of color in it that suited her better than the simplicity of the chiton. She had completed it, from the gold bangles on her wrists to the scarlet stockings and neat shoes, and was just turning to run downstairs again, when she suddenly stopped and listened. Carmel's little bedroom was really a dressing-room, and possessed two doors. One led into the passage, and the other communicated with the Blue bedroom. This latter door was ajar just a couple of inches, and through the opening came the sound of a drawer pulled out. For a moment Carmel thought that Dulcie and Bertha must have come upstairs, and she was on the point of calling to them, when some strong and mysterious instinct restrained her. Instead, she walked softly across the floor, and peeped through the chink. It was no cousin or schoolfellow who was in the next room, but a slight fair man--an utter stranger--who was hastily turning over the contents of the drawer, and slipping something into his pocket. For a moment Carmel's heart stood still. She realized instantly that she was in the immediate vicinity of a burglar. Seeing the entertainment advertised by a placard on the gate, he must have entered the garden and waited his opportunity to slip into the house while everybody was outside watching the performance. He was apparently laying light fingers upon any article which took his fancy. Carmel's first and most natural impulse was to tear downstairs and give warning of what was happening. Then it occurred to her that while she did so the thief would very possibly make his escape. If only she could trap him. But how? Her fertile brain thought for a second or two, then evolved a plan. Very quietly she withdrew the key from the door which led out of her bedroom to the passage, and locked it on the outside. So far, so good: if Mr. Burglar went into the dressing-room he could not escape. Now she must be prepared to take a great risk. The key of the Blue bedroom was on the inside; she must open the door, withdraw it, and lock it on the outside before the thief could stop her. It was possible that he had calculated on the double exit, and that, hearing a noise behind him, he would make a dash for the dressing-room.
