“First, with regard to Wentworth,” he said.  “There was a time once when he occupied very much the position that I now hold.  He was Mercer’s right-hand man.  But he took to drink, and that did for him.  I am afraid he was never very sound.  Anyhow, Mercer gave him up, and he disappeared.

“After he had gone, after I took his place, we found out one or two things he had done which might have landed him in prison if Mercer had followed them up.  However, the man was gone, and it didn’t seem worth while to track him.  It was not till afterwards that we heard he was at Bowker Creek, and Mercer was then on the point of starting for England, and decided to leave him alone.

“It’s a poor place—­Bowker Creek.  He had got a job there as boundary rider.  I suppose he counted on the shearing season to set him up.  But he wasn’t the sort of chap who ever gets on.  And when Mercer met you on his way out from the old country it was something of a shock to him to hear that you were on your way to marry Robin Wentworth.

“Of course, he ought to have told you the truth, but instead of that he made up his mind to take the business into his own hands and marry you himself.  He cabled from Colombo to Wentworth to wait for him at Bowker Creek, hinted that if he went to the coast he would have him arrested, and said something vague about coming to an understanding which induced Wentworth to obey orders.

“Then he came straight here and pressed on to Rollandstown, taking Beelzebub with him to show him the short cuts.  It’s a hard day’s ride in any case.  He reached Bowker Creek the day after, and had it out with Wentworth.  The man had been drinking, was unreasonable, furious, finally tried to shoot him.

“Well, you know Mercer.  He won’t stand that sort of thing.  He thrashed him within an inch of his life, and then made him write and give you up.  It was a despicable affair from start to finish.  Mercer’s only excuse was that Wentworth was not the sort of man to make any woman happy.  Finally, when he had got what he wanted, Mercer left him, after swearing eternal vengeance on him if he ever came within reach of you.  The rest you know.”

Yes, Sybil knew the rest.  She understood the whole story from beginning to end, realized with what unscrupulous ingenuity she had been trapped and wondered bitterly if she would ever endure her husband’s presence again without the shuddering sense of nausea which now overcame her at the bare thought of him.

She sat in stony silence, till at last Curtis paused beside her.

“I want you to rest,” he said.  “I think, if you don’t, the consequences may be serious.”

She looked up at him uncomprehendingly.

“Come, Mrs. Mercer!” he said.

She shrank at the name.

“Don’t call me that!” she said, and stumbled uncertainly to her feet.  “I—­I am going away.”

He put a steadying hand on her shoulder.
