"Tell him I wish to see him at once," he added.
She went to the door of the room.
"Ask Mr. Durham to come in," she called out. "I am glad to see you out again," she added as Durham came forward. "Mr. Harding is in here. Will you come in?"
He followed her into the room without speaking, his face so stern that a tremor of fear ran through her.
"Will you give me a few minutes alone with Mr. Harding, please, Mrs. Eustace?" he began, when his keen eyes caught sight of the open letter lying on the table.
He sprang forward and picked it up.
"How did this come here?" he cried, looking from one to the other.
"I brought it," Harding answered. "One of the troopers found it at Taloona and thought Mrs. Eustace or I had dropped it when attending to you."
"It must have fallen from my pocket," Durham said as he folded it up.
Mrs. Eustace was looking at him with anxious eyes.
