air of profound deference, "is no respecter of persons."
"But it ought to be of characters," Lady Maclure cried, warmly. "What's the good of having a blameless character, I should like to know, if—if"
"If it doesn't allow you to commit a robbery with impunity? the detective interposed, finishing her sentence his own way. "Well, well, that's true. That's perfectly true—but Sir Justin's character, you see, can hardly be called blameless."
"He's a gentleman," Persis cried, with flashing eyes, turning round upon the officer; "and he's quite incapable of such a mean and despicable crime as you dare to suspect him of."
"Oh, I see," the officer answered, like one to whom a welcome ray of light breaks suddenly through a great darkness. "Sir Justin's a friend of yours! Did he come into the porch with you?"
"He did," Persis answered, flushing crimson; "and if you have the insolence to bring a charge against him———"
"Calm yourself, madam," the detective replied, coolly. "I do nothing of the sort—at this stage of the proceedings. It's possible there may have been no robbery in the case at all. We must keep our minds open for the present to every possible alternative. It's—it's a delicate matter to hint at; but before we go any further do you think, perhaps, Sir Justin may have carried the rubies away by mistake, entangled in his clothes?—say, for example, his coat-sleeve?"
It was a loophole of escape; but Persis didn't jump at it.
"He had never the opportunity," she answered, with a flash. "And I know quite well they were there on my neck when he left me, for the last thing he said to me was, looking up at this very window: 'That balcony's awfully convenient for a burglary. Mind you take good care of the Remanet rubies.' And I remembered what he'd said when I took them off last night; and that's what makes me so sure I really had them."
"And you slept with the window open!" the detective went on, still smiling to himself. "Well, here we have all the materials, to be sure, for a first-class mystery!"

For some days more, nothing further turned up of importance about the Great Ruby Robbery. It got into the papers, of course, as everything does nowadays, and all London was talking of it. Persis found herself quite famous as the American lady who had lost her jewels. People pointed her out in the park; people stared at her hard through their opera-glasses at the theatre. Indeed, the possession of the celebrated Remanet rubies had never made her half so conspicuous in the world as the loss of them made her. It was almost worth while losing them, Persis thought, to be so much made of as she was in society in consequence. All the world knows a young lady must be somebody when she can offer a reward of five hundred pounds for the recovery of gewgaws valued at six thousand.
Sir Justin met her in the Row one day. "Then you don't go to Paris for awhile yet—until you get them back?" he inquired very low.
And Persis answered, blushing, "No, Sir Justin; not yet; and I'm almost glad of it."
"No, you don't mean that!" the young man cried, with perfect boyish ardour. "Well, I confess, Miss Remanet, the first thing I thought myself when I read it in The Times was just the very same: 'Then, after all, she won't go yet to Paris!'"
Persis looked up at him from her pony with American frankness. "And I," she, said, quivering, "I found anchor in Browning. For what do you think I read?
'And learn to rate a true man's heart.
Far above rubies.'
The book opened at the very place; and there I found anchor!"
But when Sir Justin went round to his rooms that same evening his servant said to him, "A gentleman was inquiring for you here this afternoon, sir. A close-shaven gentleman. Not very prepossessin'. And it seemed to me somehow, sir, as if he was trying to pump me."
Sir Justin's face was grave. He went to his bedroom at once. He knew what that man wanted; and he turned straight to his wardrobe, looking hard at the dress coat he had worn on the eventful evening. Things may cling to a sleeve, don't you know—or be entangled in a cuff—or get casually into a pocket! Or someone may put them there.

For the next ten days or so Mr. Gregory was busy, constantly busy. Without doubt, he was the most active and energetic of detectives. He carried out so fully his own official principle of suspecting everybody, from China to Peru, that at last poor Persis got fairly mazed with his web of possibilities. Nobody was safe from his cultivated and highly-trained suspicion—not Sir Everard in his studio, nor
