Charlotte Farnham's friends—their number was the number of those who had seen her grow from childhood to maiden—and womanhood—commonly identified her for inquiring strangers as "good old Doctor Bertie's 'only,'" adding, men and women alike, that she was as well-balanced and sensible as she was good to look upon.

As Griswold had guessed, she stood but a single remove from an American lineage much older than the America of the Middle West. Her father had been a country physician in New Hampshire, migrating to the dry winters of Minnesota for his young wife's health. The migration had been too long postponed to save the mother's life; but it had made a beautiful woman of the daughter, dowering her with the luxuriant physical charm which is the proof that transplantation to fresher soil is not less beneficial to human- than to plant-kind.

She had been spending the winter at Pass Christian with her aunt, who was an invalid; and it was for the invalid's sake that she had decided to make the return journey by river. Patient little Miss Gilman was the least querulous of sufferers, but she was always very ill on a railway train. Hence Charlotte, who was at once physician, nurse, mentor, and dutiful kinswoman to the frail little lady who looked old enough to be her grandmother, had chosen the longer, but less trying, route to the far North.

So it had come about that their state-rooms had been taken on the Belle Julie; and on the morning of the second day out from New Orleans, Miss Gilman was so far from being travel-sick that she was able to sit with Charlotte in the shade of the hurricane-deck aft, and to enjoy, with what quavering enthusiasm there was in her, the matchless scenery of the lower Mississippi.

At Baton Rouge the New Orleans papers came aboard, and Miss Farnham bought a copy of the Louisianian. As a matter of course, the first-page leader was a circumstantial account of the daring robbery of the Bayou State Security, garnished with startling head-lines. Charlotte read it, half-absently at first, and a second time with interest awakened and a quickening of the pulse when she realized that she had actually been a witness of the final act in the near-tragedy. Her little gasp of belated horror brought a query from the invalid.

"What is it, Charlie, dear?"

For answer, Charlotte read the newspaper story of the robbery, head-lines and all.

"For pity's sake! in broad daylight! How shockingly bold!" commented Miss Gilman.

"Yes; but that wasn't what made me gasp. The paper says: 'A young lady was at the teller's window when the robber came up with Mr. Galbraith—' Aunt Fanny, I was the 'young lady'!"

"You? horrors!" ejaculated the invalid, holding up wasted hands of deprecation. "To think of it! Why, child, if anything had happened, a terrible murder might have been committed right there before your very face and eyes! Dear, dear; whatever are we coming to!"

Charlotte the well-balanced, smiled at the purely personal limitations of her aunt's point of view.

"It is very dreadful, of course; but it is no worse just because I happened to be there. Yet it seems ridiculously incredible. I can hardly believe it, even now."

"Incredible? How?"

"Why, there wasn't anything about it to suggest a robbery. Now that I know, I remember that the old gentleman did seem anxious or worried, or at least, not quite comfortable some way; but the young man was smiling pleasantly, and he looked like anything rather than a desperate criminal. I can close my eyes and see him, just as I saw him yesterday. He had a good face, Aunt Fanny; it was the face of a man whom one would trust almost instinctively."

Miss Gilman's New England conservatism, unweakened by her long residence in the West, took the alarm at once.

"Did you notice him particularly, Charlotte? Would you recognize him if you should see him again?" she asked anxiously.

"Yes; I am quite sure I should."

"But no one in the bank knew you. They couldn't trace you by your father's draft and letter of identification, could they?"

Charlotte was mystified. "I should suppose they could, if they wanted to. But why? What if they could?"

"My dear child; don't you see? They are sure to catch the robber, sooner or later, and if they know how to find you, you might be dragged into court as a witness!"

Miss Farnham was not less averse to publicity than the conventionalities demanded, but she had, or believed she had, very clear and well-defined ideas of her own touching her duty in any matter involving a plain question of right and wrong.

"I shouldn't wait to be dragged," she asserted quietly. "It would be a simple duty to go willingly. The first thing I thought of was that I ought to write at once to Mr. Galbraith, giving him my address."

Thereupon issued discussion. Miss Gilman's opinion upon such a momentous question—a question involving an apparent conflict between the proprieties and an act of simple justice—leaned heavily toward silence. There could be no possible need for Charlotte's interference. Mr. Galbraith and the teller would be able to identify the robber, and a thousand eye-witnesses could do no more. At the end of the argument the conservative one had extorted a conditional promise from her niece. The matter should remain in abeyance until the question of conscientious obligation had been submitted to Charlotte's father and decided by him.

Being by nature and inclination averse to shacklings, verbal or other, Charlotte gave the promise reluctantly, and the subject was dismissed. Not from the younger woman's thoughts, however. In the reflective field the scene in the bank recurred again and again until presently it became a haunting annoyance. To banish it finally she went to her state-room and got a book for herself and a magazine for her aunt.

An hour later, when Miss Gilman had finished cutting the leaves of the magazine, and was deep in the last instalment of the current serial, Charlotte let her book slip from her fingers and gave herself to the passive enjoyment of the slowly passing panorama which is the chief charm of inland voyaging.

It was a delectable day, sweet-scented with the mingled perfume of roses and jasmine and chinaberry trees wafted from the open-air conservatories surrounding the plantation mansions on either bank. The majestic onrush of the steamer, the rhythmic drumbeat of the machinery, the alternating crash and pause of the great paddle-wheels, the unhasting backward sweep of the brown flood, all these were in harmony with the sensuous languor of time and place.

For the moment Charlotte Farnham yielded in pure delight to the spell of the encompassments, fancying she could deny her lineage and look upon this sylvan Southland world through the eyes of those to whom it was the birthland. Then the haunting scene in the New Orleans bank returned to disenchant her; and after striving vainly to put it aside, she reopened her book. But by this time the story had lost its hold upon her, and when she had read a page or two with only the vaguest possible notion of what it was all about, she gave up in despair and let the relentless recollection have its will of her.

From where she was sitting she could see the steamer's yawl swinging from its tackle at the stern-staff; and after many minutes it was slowly borne in upon her that the ropes were working loose. When it became evident that the boat would shortly fall into the river and go adrift, she got up and put the book aside, meaning to go forward and tell the captain. But before she had taken the first step a man came aft to make the loosened tackle fast, and she stood back to let him pass.

It was Griswold. Up to that moment he had thrown himself so zealously into the impersonation of his latest rÔle as to be able to stand indifferently well in the shoes of the man whom he had supplanted. But at this crisis the machinery of dissimulation slipped a cog. Where the ordinary deck-hand would have gone about his errand heedless of the presence of the two women passengers, the proxy John Wesley Gavitt must needs take off his cap and apologize for passing in front of them.

Something half familiar in his manner of doing it attracted Charlotte's attention, and her eyes followed him as he went on and hoisted the yawl into place. When he came back she had a fair sight of his face and her eyes met his. In the single swift glance half-formed suspicion became undoubted certainty; she looked again and her heart gave a great bound and then seemed suddenly to forget its office. While he was passing she clung to the back of her chair and forebore to cry out or otherwise to advertise her emotion. But when the strain was off she sank into her seat and closed her eyes to grapple with the unnerving discovery. It was useless to try to escape from the dismaying fact. The stubble-bearded deck-hand with the manners of a gentleman was most unmistakably a later reincarnation of the pleasantly smiling young man who had courteously made way for her at the teller's wicket in the Bayou State Security; who had smiled and given place to her while he was holding his pistol aimed at President Galbraith.

It was said of Charlotte Farnham that she was sensible beyond her years, and withal strong and straightforward in honesty of purpose. None the less, she was a woman. And when she saw what was before her, conscience turned traitor and fled away to give place to an uprush of hesitant doubts born of the sharp trial of the moment.

She decided at once that there could be no question as to her duty. Of all those who were seeking the escaping bank robber, it was doubtful if any would recognize him as she had; and if she should hold her peace he would escape, perhaps to commit other crimes for which she could then justly be held accountable.

But, on the other hand, how could she bring herself to the point of giving him over to the vengeance of the law—just vengeance, to be sure, but cruel because it must inevitably crush out whatever spark of penitence or good intention there might be remaining in him? What did she know of his temptations? of the chain of circumstances which had dragged him down into the company of the desperately criminal? Some such compelling influence there must have been, she reasoned, since a child might see that he was no hardened felon. It was a painful conflict, but in the end the Puritan conscience triumphed and turned mercy out of doors. Her duty was plain; she had no right to argue the question of culpability.

She got upon her feet, steadying herself by the back of the chair. She felt that she could not trust herself if she once admitted the thin edge of the wedge of delay. The simple and straightforward thing to do was to go immediately to the captain and tell him of her discovery, but she shrank from the thought of what must follow. They would seize him: he had proved that he was a desperate man, and there would be a struggle. And when the struggle was over they would bring him to her and she would have to stand forth as his accuser.

It was too shocking, and she caught at the suggestion of an alternative with a gasp of relief. She might write to President Galbraith, giving such a description of the deck-hand as would enable the officers to identify him without her personal help. It was like dealing the man a treacherous blow in the back, but she thought it would be kinder.

"Aunt Fanny," she began, with her face averted, "I promised you I wouldn't write to Mr. Galbraith until after we reached home—until I had told papa. I have been thinking about it since, and I—I think it must be done at once."

Now Miss Gilman's conscience was also of the Puritan cast, and justice had been given time to make its claim paramount to that of the conventional proprieties. Hence the invalid yielded the point without reopening the argument.

"I don't know but you are right, after all, Charlie, dear," she said. "I've been thinking it over, too. But it seems like a very dreadful thing for you to have to do."

"It is very dreadful," said Charlotte, with a much deeper meaning in the words than her aunt suspected. Nevertheless, she went away quickly and locked herself in her state room to write the fateful letter which should set the machinery of the law in motion and deliver the robber deck-hand up to justice.
