XXII. O. B. AGAIN
"What's happened? Something very important. I ought to hope so afterthis confounded failure."
"Failure? Didn't he read the letters?"
"Yes, he read them. Had to, but--"
"Didn't weaken? Eh?"
"No, he didn't weaken. You can't get water out of a millstone. You maysqueeze and squeeze; but it's your fingers which suffer, not it. Hethinks we manufactured those letters ourselves on purpose to draw him."
"Humph! I knew we had a reputation for finesse, but I didn't know thatit ran that high."
"He denies everything. Said she would never have written such letters tohim; even goes so far to declare that if she did write them--(he mustbe strangely ignorant of her handwriting) they were meant for someother man than himself. All rot, but--" A hitch of the shoulder conveyedSweetwater's disgust. His uniform good nature was strangely disturbed.
But Mr. Gryce's was not. The faint smile with which he smoothed with aneasy, circling movement, the already polished top of his everpresent cane conveyed a secret complacency which called up a flash ofdiscomfiture to his greatly irritated companion.
"He says that, does he? You found him on the whole tolerablystraightforward, eh? A hard nut; but hard nuts are usually sound ones.Come, now! prejudice aside, what's your honest opinion of the man you'vehad under your eye and ear for three solid weeks? Hasn't there been thebest of reasons for your failure? Speak up, my boy. Squarely, now."
"I can't. I hate the fellow. I hate any one who makes me lookridiculous. He--well, well, if you'll have it, sir, I will say thismuch. If it weren't for that blasted coincidence of the two deathsequally mysterious, equally under his eye, I'd stake my life on hishonesty. But that coincidence stumps me and--and a sort of feeling Ihave here."
It is to be hoped that the slap he gave his breast, at this point,carried off some of his superfluous emotion. "You can't account for afeeling, Mr. Gryce. The man has no heart. He's as hard as rocks."
"A not uncommon lack where the head plays so big a part. We can't hanghim on any such argument as that. You've found no evidence against him?"
"N--no." The hesitating admission was only a proof of Sweetwater'sobstinacy.
"Then listen to this. The test with the letters failed, because what hesaid about them was true. They were not meant for him. Miss Challonerhad another lover."
"Only another? I thought there were a half-dozen, at least."
"Another whom she favoured. The letters found in her possession--notthe ones she wrote herself, but those which were written to her over thesignature O. B. were not all from the same hand. Experts have been busywith them for a week, and their reports are unanimous. The O. B. whowrote the threatening lines acknowledged to by Orlando Brotherson, wasnot the O. B. who penned all of those love letters. The similarity inthe writing misled us at first, but once the doubt was raised by Mr.Challoner's discovery of an allusion in one of them which pointed toanother writer than Mr. Brotherson, and experts had no difficulty inreaching the decision I have mentioned."
"Two O. B.s! Isn't that incredible, Mr. Gryce?"
"Yes, it is incredible; but the incredible is not the impossible. Theman you've been shadowing denies that these expressive effusions of MissChalloner were meant for him. Let us see, then, if we can find the manthey were meant for."
"The second O. B.?"
"Yes."
Sweetwater's face instantly lit up.
"Do you mean that I--after my egregious failure--am not to be kept onthe dunce's seat? That you will give me this new job?"
"Yes. We don't know of a better man. It isn't your fault, you said ityourself, that water couldn't be squeezed out of a millstone."
"The Superintendent--how does he feel about it?"
"He was the first one to mention you."
"And the Inspector?"
"Is glad to see us on a new tack."
A pause, during which the eager light in the young detective's eyeclouded over. Presently he remarked:
"How will the finding of another O. B. alter Mr. Brotherson's position?He still will be the one person on the spot, known to have cherisheda grievance against the victim of this mysterious killing. To my mind,this discovery of a more favoured rival, brings in an element of motivewhich may rob our self-reliant friend of some of his complacency. We mayfurther, rather than destroy, our case against Brotherson by locating asecond O.B."
Mr. Gryce's eyes twinkled.
"That won't make your task any more irksome," he smiled. "The loop wethus throw out is as likely to catch Brotherson as his rival. It alldepends upon the sort of man we find in this second O. B.; and whether,in some way unknown to us, he gave her cause for the sudden andoverwhelming rush of despair which alone supports this general theory ofsuicide."
"The prospect grows pleasing. Where am I to look for my man?"
"Your ticket is bought to Derby, Pennsylvania. If he is not employed inthe great factories there, we do not know where to find him. We have noother clew."
"I see. It's a short journey I have before me."
"It'll bring the colour to your cheeks."
"Oh, I'm not kicking."
"You will start to-morrow."
"Wish it were to-day."
"And you will first inquire, not for O. B., that's too indefinite; butfor a young girl by the name of Doris Scott. She holds the clew; orrather she is the clew to this second O. B."
"Another woman!"
"No, a child;--well, I won't say child exactly; she must be sixteen."
"Doris Scott."
"She lives in Derby. Derby is a small place. You will have no troublein finding this child. It was to her Miss Challoner's last letter wasaddressed. The one--"
"I begin to see."
"No, you don't, Sweetwater. The affair is as blind as your hat; nobodysees. We're just feeling along a thread. O. B.'s letters--the realO. B., I mean, are the manliest effusions possible. He's no more ofa milksop than this Brotherson; and unlike your indomitable friend heseems to have some heart. I only wish he'd given us some facts; theywould have been serviceable. But the letters reveal nothing exceptthat he knew Doris. He writes in one of them: 'Doris is learning toembroider. It's like a fairy weaving a cobweb!' Doris isn't a verycommon name. She must be the same little girl to whom Miss Challonerwrote from time to time."
"Was this letter signed O. B.?"
"Yes; they all are. The only difference between his letters andBrotherson's is this: Brotherson's retain the date and address; thesecond O. B.'s do not."
"How not? Torn off, do you mean?"
"Yes, or rather, neatly cut away; and as none of the envelopes werekept, the only means by which we can locate the writer is through thisgirl Doris."
"If I remember rightly Miss Challoner's letter to this child was freefrom all mystery."
"Quite so. It is as open as the day. That is why it has been mentionedas showing the freedom of Miss Challoner's mind five minutes before thatfatal thrust."
Sweetwater took up the sheet Mr. Gryce pushed towards him and re-readthese lines:
"Dear Little Doris:
"It is a snowy night, but it is all bright inside and I feel no chill in mind or body. I hope it is so in the little cottage in Derby; that my little friend is as happy with harsh winds blowing from the mountains as she was on the summer day she came to see me at this hotel. I like to think of her as cheerful and beaming, rejoicing in tasks which make her so womanly and sweet. She is often, often in my mind.
"Affectionately your friend, "EDITH A. CHALLONER."
"That to a child of sixteen!"
"Just so."
"D-o-r-i-s spells something besides Doris."
"Yet there is a Doris. Remember that O. B. says in one of his letters,'Doris is learning to embroider.'"
"Yes, I remember that."
"So you must first find Doris."
"Very good, sir."
"And as Miss Chall
oner's letter was directed to Derby, Pennsylvania, youwill go to Derby."
"Yes, sir."
"Anything more?"
"I've been reading this letter again."
"It's worth it."
"The last sentence expresses a hope."
"That has been noted."
Sweetwater's eyes slowly rose till they rested on Mr. Gryce's face:"I'll cling to the thread you've given me. I'll work myself through thelabyrinth before us till I reach HIM."
Mr. Gryce smiled; but there was more age, wisdom and sympathy foryouthful enthusiasm in that smile than there was confidence or hope.
