The young man frowned.  Another interruption!  And Miss Bowman!  It was at her house that he was to dine.  What could the woman want?  Surely it was not so late that she was looking him up.  But perhaps something had happened, and she was calling off her dinner.  What luck if she was!  Then he would be free to attend the problem of the young woman whom fate, or Providence, had suddenly thrust upon his care.

He took the receiver, resolved to get out of going to the dinner if it were possible.

“Good evening, Mrs. Bowman.”

“Oh, is that you, Mr. Dunham?  How relieved I am!  I am in a bit of difficulty about my dinner, and called up to see if your sister couldn’t help me out.  Miss Mayo has failed me.  Her sister has had an accident, and she cannot leave her.  She has just ’phoned me, and I don’t know what to do.  Isn’t Cornelia at home?  Couldn’t you persuade her to come and help me out?  She would have been invited in Miss Mayo’s place if she had not told me that she expected to go to Boston this week.  But she changed her plans, didn’t she?  Isn’t she where you could reach her by ’phone and beg her to come and help me out?  You see, it’s a very particular dinner, and I’ve made all my arrangements.”

“Well, now, that’s too bad, Mrs. Bowman,” began the young man, thinking he saw a way out of both their difficulties.  “I’m sorry Cornelia isn’t here.  I’m sure she would do anything in her power to help you.  But she and mother were to dine in Chestnut Hill to-night, and they must have left the house half an hour ago.  I’m afraid she’s out of the question.  Suppose you leave me out?  You won’t have any trouble then except to take two plates off the table”—­he laughed pleasantly—­“and you would have even couples.  You see,” he hastened to add, as he heard Mrs. Parker Bowman’s preliminary dissent—­“you see, Mrs. Bowman, I’m in somewhat of a predicament myself.  My train was late, and as I left the station I happened to meet a young woman—­a—­a friend.” (He reflected rapidly on the old proverb, “A friend in need is a friend indeed.”  In that sense she was a friend.) “She is temporarily separated from her friends, and is a stranger in the city.  In fact, I’m the only acquaintance or friend she has, and I feel rather under obligation to see her to her hotel and look up trains for her.  She leaves the city to-night.”

“Now, look here, Tryon Dunham, you’re not going to leave me in the lurch for any young woman.  I don’t care how old an acquaintance she is!  You simply bring her along.  She’ll make up my number and relieve me wonderfully.  No, don’t you say a word.  Just tell her that she needn’t stand on ceremony.  Your mother and I are too old friends for that.  Any friend of yours is a friend of mine, and my house is open to her.  She won’t mind.  These girls who have travelled a great deal learn to step over the little formalities of calls and introductions.  Tell her I’ll call on her afterwards, if she’ll
