When Willie entered a few moments later in search of his co-laborer, Delight was alone. He glanced questioningly about the room,--at the girl's flushed cheeks, the half-made cake, the snowy floor.

"Bob--Mr. Morton spilled some flour," the young woman explained, evading his eye.

The little old man made no response. He studied the burning face, the drooping lashes; he also looked meditatively at some footprints on the floor. They may not have been as startling in their significance as were the famous marks Crusoe discovered in the sand, but they were quite as illuminating.

A trail of small ones led about the room and beside them, as if echoing to their light tread, was a series of larger ones. The inventor's gaze pursued them curiously to a spot before the stove where they became very much confused and afterward branched apart, the larger set trailing off toward the stairs, and the smaller moving back into the pantry.

The detective stroked his chin for an interval.

"U--m!" observed he thoughtfully.

CHAPTER XIII

A NEWCOMER ENTERS

The next day Mr. Howard Snelling made his appearance at the Spence workshop.

Bob was fitting wire netting to some metal uprights and struggling to focus his mind on what he was doing enough to forget that Delight Hathaway was on the other side of the part.i.tion when from the window above the bench he saw Cynthia Galbraith come rolling up to the gate in her runabout, accompanied by a strikingly handsome stranger.

He hurried out to meet them.

Her father and Roger, the girl said, had gone to a yacht race at Hyannis, so she had brought Mr. Snelling over. She introduced the two men but refused somewhat curtly to come in, explaining that she would be back, or some one else would, to fetch the guest home to Belleport for luncheon. Then, without a backward glance, she started the engine and disappeared around the curve of the Harbor Road.

Perhaps it was just as well, Robert Morton reflected, that she had not accepted his invitation to come in, for to bring her and Delight together at this delicate juncture might result in awkwardness; nevertheless, it certainly was something unprecedented for Cynthia to be so brusque and be in such a hurry. The enigma puzzled him, and he found it recurring to his mind persistently. However, he resolutely shook it off and turned his attention instead to his new acquaintance.

He was, he could not but admit, quite unprepared to find Mr. Howard Snelling, his future chief, possessed of so attractive a personality.

Mr. Galbraith, when alluding to the expert craftsman, had never mentioned his age, and Bob had gleaned the impression that the man before whose ability the entire Galbraith shipbuilding plant bowed down was middle-aged, possibly even elderly. Therefore to be confronted by some one in the early forties was a distinct shock.

Snelling's hair was, to be sure, sprinkled lightly with gray, but this hint of maturity was given the lie by his ruddy, unlined countenance and the youthfulness with which he wore his clothes. A good tailor had evidently found a model worthy of his skill and had tried to live up to the task set him, for everything in the stranger's att.i.tude and appearance proclaimed smartness and the _savoir faire_ of the man about town. Yet Howard Snelling was something far better than either a fashion plate or a society darling. He was energy personified. It spoke in every motion of his strong, fine hands, in the quick turn of his head, in the alert attention with which he listened. Nothing escaped his well-trained eye. One's very thoughts seemed to be at his mercy. Mingling, however, with these more astute qualities and counterbalancing them was a winning tact and courtesy which instantly put another at his ease. Without these characteristics Mr. Snelling would have been unbearable; but with them he was thoroughly charming.

"Well, Morton, I am glad to have a chance to meet you in the flesh," he said, as they still loitered at the gate. "The Galbraiths have sung your praises until I began to think you a sort of myth. You certainly have something to live up to if you are to reach the reputation they have painted of your virtues. Mr. Galbraith, in particular, thinks there is no obstacle that you cannot conquer."

He swept his eye curiously over the young man before him.

"You mustn't believe a word of what they've told you, Mr. Snelling,"

laughed Robert Morton. "Our friends are always over-indulgent to our faults. When I begin work under you, a thing I am greatly antic.i.p.ating, you will find out what a duffer I really am."

The elder man smiled.

"I'm ready to take the chance," said he.

"Besides," Bob went on, "Mr. Galbraith has given you something of a character too. He has frightened me clean out of my life with his tales of your--"

"Pooh! Nonsense!" broke in Mr. Snelling deprecatingly. "I like my job, that's all; and Mr. Galbraith and I happen to hit it off."

Nevertheless Bob could see that he was pleased by the flattery.

It was on his tongue's end to voice his thought and add that the man who could not get on with a person of Mr. Snelling's adroitness and diplomacy would be hard to please; but although he did not utter the words he felt them to be true.

"Now," began the New Yorker with a swift change of subject, "let us get down to business. How are we going to work this thing? You must coach me. I gather I am being employed on quite a delicate mission. My instructions are to come in here as a friend of yours and the Galbraiths, and without raising the suspicion that I have much of any knowledge about boats, I am to help get this invention into workable shape. Any parts we lack, any drawings we wish made, any materials we need I have authority to procure from our Long Island plant. There is to be no stint as to expense. The enterprise is to be carried through to the finish properly."

Robert Morton gasped.

"I had no idea Mr. Galbraith meant to go into it to such lengths," he murmured.

"Oh, Mr. Galbraith never does things by halves when once he is interested," was the reply. "Besides, he has a hunter's scent for the commercial. He says there is a live idea here that has money in it, and that's enough for him. Anyway, whether there is or not," Snelling added hurriedly, "we are to humor the old gentleman's whims and get his idea so he can handle it."

"It is tremendously generous of Mr. Galbraith."

Howard Snelling regarded his companion quizzically for a moment, then remarked with gravity:

"Oh, there is a kind heart in Mr. Galbraith, in spite of all his business instincts."

"Had you ever met the rest of the family before now?" questioned Bob more with a desire to turn the channel of conversation than because he had any interest in the matter.

The inquiry, idly made, produced an unexpected result, visibly throwing the expert out of his imperturbable composure; he flushed, stammered, and bit his lip before he successfully conquered his confusion:

"I--eh--oh, yes," was his reply. "I've been a dinner guest at the New York house several times; been sent for on a pinch to help out. Then Mr. Galbraith summons me there occasionally for consultation on business matters. The Belleport place is attractive, isn't it?"

"It's corking!"

"I suppose you spend a lot of time over there," ventured Snelling, lighting a gold-tipped Egyptian cigarette and offering Bob one.

Something in the question, he could not have told what, caused Robert Morton to dart a quick, furtive glance at the speaker.

Mr. Snelling was smoking and blowing indifferently into the air filmy rings of smoke, but through it the disconcerted young man encountered his penetrating gaze.

"I don't get over there very often," said Bob. "This invention keeps me rather busy."

"Of course, of course!" was the cordial response. "And now as to our policy on this deal. I shall follow your lead, understand. Any a.s.sertion you see fit to make you can trust me to swear to. You may introduce me to the old chap as your college pal, even your long-lost brother, if you choose."

"I hardly think that will be necessary," Robert Morton answered, a hint of coldness in his voice. "I shall simply introduce you for what you are, Mr. Galbraith's friend--"

"And yours," smiled Mr. Snelling, graciously placing a hand on the young man's shoulder.

It was unaccountable, absurd, that Bob should have shrunk at the touch; nevertheless he did so.

"Don't you think," he replied abruptly, "that the sooner we go in and get to work the better? How long do you expect to be able to stay here?"

Again the color crept into Snelling's cheek, but this time he was quite master of himself.

"I cannot tell yet. It will depend to some extent on how we get on."

"I suppose you really can't be spared from the Long Island plant a great while."

"As to that, Mr. Galbraith is all-powerful," was his smiling answer.

"What he wills must be arranged. Fortunately just now business is running slack, at least my part of it is. Most of our contracts are well on the way to completion and others can carry them out, so I can stay down here as long as is necessary. It can go as my vacation, if worst comes to worst. Hence you see," concluded he, pulling a spray of honeysuckle to pieces, "we don't need to rush things."
