The boy smiled a happy smile. "I'll go," he said resolutely.

"Thanks, awfully," said Miss Brodie. "I shall feel so much safer with you in the waiting room."

It was a difficult matter to surprise Mr. Rae, and even more difficult to extract from him any sign of surprise, but when Dunn, leaving Miss Brodie and his brother in the anteroom, entered Mr. Rae's private office and laid the letter for Mr. Sheratt before him, remarking, "This letter is from Sir Archibald, and withdraws the prosecution," Mr. Rae stood speechless, gazing now at the letter in his hand, and now at Mr. Dunn's face.

"G.o.d bless my soul! This is unheard of. How came you by this, Sir?"

"Miss Brodie--" began Dunn.

"Miss Brodie?"

"She is in the waiting room, Sir."

"Then, for heaven's sake, bring her in! Davie, Davie! Where is that man now? Here, Davie, a message to Mr. Thomlinson."

Davie entered with deliberate composure.

"My compliments to Mr. Thomlinson, and ask if he would step over at once. It is a matter of extreme urgency. Be quick!"

But Davie had his own mind as to the fitness of things. "Wad a note no'

be better, Sir? Wull not--?"

"Go, will you!" almost shouted Mr. Rae.

Davie was so startled at Mr. Rae's unusual vehemence that he seized his cap and made for the door. "He'll no' come for the like o' me," he said, pausing with the door-k.n.o.b in his hand. "It's no' respectable like tae--"

"Man, will ye no' be gone?" cried Mr. Rae, rising from his chair.

"I will that!" exclaimed Davie, banging the door after him. "But," he cried furiously, thrusting his head once more into the room, "if he'll no' come it's no' faut o' mine." His voice rose higher and higher, and ended in a wrathful scream as Mr. Rae, driven to desperation, hurled a law book of some weight at his vanishing head.

"The de'il take ye! Ye'll be my deith yet."

The book went crashing against the door-frame just as Miss Brodie was about to enter. "I say," she cried, darting back. "Heaven protect me!

Rob, save me!"

Rob sprang to her side. She stood for a moment gazing aghast at Mr.

Dunn, who gazed back at her in equal surprise. "Is this his 'usual'?"

she inquired.

At that the door opened. "Ah, Mr. Dunn, this is Miss Brodie, I suppose.

Come in, come in!" Mr. Rae's manner was most bland.

Miss Brodie gave him her hand with some hesitation. "I'm very glad to meet you, Mr. Rae, but is this quite the usual method? I mean to say, I've heard of having advice hurled at one's head, but I can't say that I ever was present at a demonstration of the method."

"Oh," said Mr. Rae, with bland and gallant courtesy, "the method, my dear young lady, varies with the subject in hand."

"Ah, the subject!"

"And with the object in view."

"Oh, I see."

"But pray be seated. And now explain this most wonderful phenomenon." He tapped the letter.

"Oh, that is quite simple," said Miss Brodie. "I set the case of young Mr. Cameron before my uncle, and of course he at once saw that the only thing to do was withdraw the prosecution."

Mr. Rae stood gazing steadily at her as if striving to take in the meaning of her words, the while s.c.r.e.w.i.n.g up his ear most violently till it stuck out like a horn upon the side of his shiny, bald head. "Permit me to say, Miss Brodie," he said, with a deliberate and measured emphasis, "that you must be a most extraordinary young lady." At this point Mr. Rae's smile broke forth in all its glory.

"Oh, thank you, Mr. Rae," replied Miss Brodie, smiling responsively at him. "You are most--" But Mr. Rae's smile had vanished. "What! I beg your pardon!" Miss Brodie's smiling response was abruptly arrested by finding herself gazing at a face whose grave solemnity rebuked her smile as unwarranted levity.

"Not at all, not at all!" said Mr. Rae. "But now, there are matters demanding immediate action. First, Mr. Sheratt must receive and act upon this letter without delay." As he spoke he was scribbling hastily a note. "Mr. Dunn, my young men have gone for the day. Might I trouble you?"

"Most certainly," cried Mr. Dunn. "Is an answer wanted?"

"Bring him with you, if possible; indeed, bring him whether it is possible or not. But wait, it is past the hour appointed. Already the officer has gone for young Cameron. We must save him the humiliation of arrest."

"Oh, could I not warn him?" cried Miss Brodie eagerly. "No," she added, "Rob will go. He is in the waiting room now, poor little chap. It will be a joy to him."

"It is just as well Rob should know nothing. He is awfully fond of Cameron. It would break his heart," said Mr. Dunn.

"Oh, of course! Quite unnecessary that he should know anything. We simply wish Cameron here at the earliest possible moment."

Dunn went with his young brother down the stairs and out to the street.

"Now, Rob, you are to go to Cameron's lodgings and tell him that Mr. Rae wants him, and that I want him. Hold on, youngster!" he cried, grabbing Rob by the collar, "do you understand? It is very important that Cameron should get here as quick as he possibly can, and--I say, Rob," the big brother's eyes traveled over the darkening streets that led up into the old town, "you're not afraid?"

"A wee bit," said Rob, tugging at the grasp on his collar; "but I don't care if I am."

"Good boy!" cried his brother. "Good little brick! I wouldn't let you go, but it's simply got to be done, old chap. Now fly!" He held him just a moment longer to slap him on the back, then released his hold. Dunn stood watching the little figure tearing up the North Bridge. "Great little soul!" he muttered. "Now for old Sheratt!"

He put his head down and began to bore through the crowd toward Mr.

Sheratt's house. When he had gone but a little distance he was brought up short by a bang full in the stomach. "Why, what the deuce!"

"Dod gast ye! Whaur are ye're een?" It was Davie, breathless and furious from the impact. "Wad ye walk ower me, dang ye?" cried the little man again. Davie was Free Kirk, and therefore limited in the range of his vocabulary.

"Oh! That you, Davie? I'm sorry I didn't see you."

"A'm no' as big as a hoose, but a'm veesible." And Davie walked wrathfully about his business.

"Oh, quite," acknowledged Dunn cheerfully, hurrying on; "and tangible, as well."

"He's comin'," cried Davie over his shoulder; "but gar it had been masel'," he added grudgingly, "catch me!"

But Dunn was too far on his way to make reply. Already his mind was on the meeting of the lawyers in Mr. Rae's office, and wondering what would come of it. On this subject he meditated until he reached Mr. Sheratt's home. Twice he rang the bell, still meditating.

"By Jove, she is stunning! She's a wonder!" he exclaimed to himself as he stood in Mr. Sheratt's drawing-room. "She's got 'em all skinned a mile, as Martin would say." It is safe to affirm that Mr. Dunn was not referring to the middle-aged and highly respectable maid who had opened the door to him. It is equally safe to affirm that this was the unanimous verdict of the three men who, half an hour later, brought their deliberations to a conclusion, frankly acknowledging to each other that what they had one and all failed to achieve, the lady had accomplished.
