Mascola's eyes darted about the floor, coming to rest upon a big vat only a few feet away. For an instant he hesitated. A faint metallic click from the doorway caused him to make up his mind. His body straightened as his hands traveled upward to the level of his shoulders. The palm of his right hand opened and a thin two-edged blade rattled to the floor.

Gregory took a step forward and shoved the knife away with his foot. Keeping one eye fixed warily upon Mascola, he shot a glance over his shoulder to determine the author of the interruption.

He turned to see a trim little figure in loosely-fitting outing clothes striding across the floor. Facing the light which streamed in from the open door, he could not distinguish the newcomer's face. He only noted the ease of the stranger's movements, the poise of the uptilted head and the nervous manner with

which the Italians fell away before the advancing figure.

"What's the trouble?"

Gregory stared. It was a girl. She had turned into the light and was facing him. As he formed an answer to her question he saw that her sun-bronzed cheeks were flushed with red and her clear brown eyes were looking into his inquiringly. In her hand she held an automatic revolver.

Gregory strove to make his explanation brief.

"These men refused to work. I told them to go. Mascola and I had some trouble. He drew his knife. Then you came."

The girl nodded, dislodging a lock of red-gold hair from under her knitted cap. Turning quickly to Mascola, she commanded: "Get out."

Mascola made no sign that he intended to comply with the order. With folded arms he looked insolently at the speaker.
