“Something in it, possibly, do you think?” James Macauley asked, in an aside, of Mrs. Burns.  “Miss Mathewson certainly has developed a lot of good looks this summer that I, for one, never suspected her of before.  Whether she could interest a man like him I don’t know and can’t guess.  He’s no ordinary man.  I didn’t like him much at first, but as he’s improved in health he’s shown up for what he is, and I can understand Red’s interest in getting him on his feet again.  He’s certainly on ’em now.  That was a great stunt he did for the little chap, according to Red.  Looks a bit suggestive of interest, his going off with Miss Amy for a walk, at the last minute, don’t you think?  Still, I can’t imagine any man’s looking in that direction when there’s what there is across the street.  He hasn’t shown any signs of life, there, has he?”

“Jimmy, you’re a sad gossip.  If I knew all these people’s affairs, or if I knew none of them, I shouldn’t discuss them with you.  But I’m quite willing to agree with you that both Amy and Charlotte are delightful, each in her way.”

“Never did get any satisfaction out of you,” grumbled James Macauley, good humouredly.  “I didn’t suppose women had such a fine sense of honour when it came to talking over other women.”

“Then it’s time you found it out.”

“What’s this?  Ellen giving you hot shot?” Burns came up, watch in hand.  “It’s time those people were back.  They’ve probably fallen into a discussion of surgical methods, and forgotten the time.”

The missing pair presently appeared.  James Macauley looked curiously at them, but could detect no sign of sentiment about them.  Indeed, as they came up the walk Leaver’s voice was heard saying in a most matter-of-fact way: 

“I’ll send you a reprint on that subject.  You’ll find the German notion has completely changed—­completely.  Nothing has happened in a long time that so marks advance in research along those lines.”

“He’s safe,” the observer whispered to Mrs. Burns.  “No fun to be had out of that.  Unless—­he was clever enough to change his line when he came within earshot.  It has been done, you know.  I’ve done it myself, though I never jumped to German reprints as a safety station.  But, you can usually tell by the woman.  She looks as if she had merely been out for a nice walk.  Not a hair out of place, no high colour, no—­”

Ellen moved away from him.  She was conscious that she, too, had been noting signs, but she would not join him further in discussing them.

“I am not good at farewell speeches,” said John Leaver, holding Ellen’s hand in both his own, when he had taken leave of every one else.  “I only hope I can show you, somehow, how I feel about what you and your husband have done for me.  I tried to tell Miss Mathewson something of the same thing, but she wouldn’t have it, which was fortunate, for the words stuck in my throat.”

Burns took him away.  “If they hadn’t, you’d have missed your train.  We’ve got to make time, now.”
