A man may be in sympathy with the modern movement for the emancipation of woman and yet feel aggrieved when a mere girl proves herself a more efficient thief than himself.  Woman is invading man’s sphere more successfully every day; but there are still certain fields in which man may consider that he is rightfully entitled to a monopoly—­and the purloining of scarabs in the watches of the night is surely one of them.  Joan, in Ashe’s opinion, should have played a meeker and less active part.

These unworthy emotions did not last long.  Whatever his other shortcomings, Ashe possessed a just mind.  By the time he had found Joan, after Mr. Peters had said his say, and dispatched him below stairs for that purpose, he had purged himself of petty regrets and was prepared to congratulate her whole-heartedly.  He was, however, resolved that nothing should induce him to share in the reward.  On that point, he resolved, he would refuse to be shaken.

“I have just left Mr. Peters,” he began.  “All is well.  His check book lies before him on the table and he is trying to make his fountain pen work long enough to write a check.  But there is just one thing I want to say—­”

She interrupted him.  To his surprise, she was eyeing him coldly and with disapproval.

“And there is just one thing I want to say,” she said; “and that is, if you imagine I shall consent to accept a penny of the reward—­”

“Exactly what I was going to say.  Of course I couldn’t dream of taking any of it.”

“I don’t understand you.  You are certainly going to have it all.  I told you when we made our agreement that I should only take my share if you let me do my share of the work.  Now that you have broken that agreement, nothing could induce me to take it.  I know you meant it kindly, Mr. Marson, but I simply can’t feel grateful.  I told you that ours was a business contract and that I wouldn’t have any chivalry; and I thought that after you had given me your promise—­”

“One moment,” said Ashe, bewildered.  “I can’t follow this.  What do you mean?”

“What do I mean?  Why, that you went down to the museum last night before me and took the scarab, though you had promised to stay away and give me my chance.”

“But I didn’t do anything of the sort.”

It was Joan’s turn to look bewildered.

“But you have got the scarab, Mr. Marson?”

“Why, you have got it!”

“No!”

“But—­but it has gone!”

“I know.  I went down to the museum last night, as we had arranged; and when I got there there was no scarab.  It had disappeared.”

They looked at each other in consternation.  Ashe was the first to speak.

“It was gone when you got to the museum?”

“There wasn’t a trace of it.  I took it for granted that you had been down before me.  I was furious!”

“But this is ridiculous!” said Ashe.  “Who can have taken it?  There was nobody beside ourselves who knew Mr. Peters was offering the reward.  What exactly happened last night?”
