"I didn't hear you," Bob said. "Probably my heart was in my mouth, and beating so loud that it deafened me; for, of course, I knew I carried my life in my hand."

"Your life in your hand?" repeated Eustace wonderingly.

"Certainly. I felt sure you would bound on me with a revolver the moment you heard me, shoot me dead, and then demand an explanation. It is the sort of ardent thing one might expect from a knight of your order, Sir Eustace."

Bob's chaff went deeper home than he meant it to. Eustace was in no mood for joking after the strain of the last few minutes. He hoped with all his heart that Mrs. Orban would not betray to Bob how terror-stricken he had just shown himself. Perhaps she understood, or it may be that she was half ashamed of her own unnecessary panic, for she only said,—

"It is really very good of you to have come in the face of that grave peril, and at such an hour too."

"Well, the fact is I wanted to," Bob said in his casual way, "and the mater insisted. I've left our old foreman sleeping in the house for to-night, and I thought I would just turn in with Eustace, if you don't mind."

"We shall be simply delighted," Mrs. Orban said, with a feeling of real relief.

"The mater wants me to take you all back to the Highlands early to-morrow," Bob went on; "you, Becky, and Eustace. She can't bear to think of your loneliness here. Do come and stay with us till Mr. Orban comes back."

It was the kind of thought good, homely little Mrs. Cochrane was celebrated for. But Mrs. Orban shook her head.

"It is just like your mother to think of such a thing," she said, "and just like her son to be her messenger so readily, but I can't do it, Bob. I couldn't possibly leave the maids and the house to take care of themselves. Mary and Kate would be terrified."
