Could this little store, the Jack of Hearts, be the central point of the mystery? In his search for information Curly had already been in it, had bought a cigar, and had stopped to talk with Mrs. Wylie, the proprietor.

She was a washed-out little woman who had once been pretty. Habitually she wore a depressed, hopeless look, the air of pathetic timidity that comes to some women who have found life too hard for them. It had been easy to alarm her. His first question had evidently set her heart a-flutter, but Flandrau had rea.s.sured her cheerfully. She had protested with absurd earnestness that she had seen nothing of Mr. Cullison. A single glance had been enough to dismiss her from any possible suspicion.

Now Curly stepped in a second time. The frightened gaze of Mrs. Wylie fastened upon him instantly. He observed that her hand moved instinctively to her heart. Beyond question she was in fear. A flash of light clarified his mind. She was a conspirator, but an unwilling one. Possibly she might be the author of the anonymous warnings sent Bolt.

The young _vaquero_ subscribed for a magazine and paid her the money.

Tremblingly she filled out the receipt. He glanced at the slip and handed it back.

"Just write below the signature 'of the Jack of Hearts,' so that I'll remember where I paid the money if the magazine doesn't come," he suggested.

She did so, and Curly put the receipt in his pocket carelessly. He sauntered leisurely to the hotel, but as soon as he could get into a telephone booth his listlessness vanished. Maloney had returned to town and he telephoned him to get Mackenzie at once and watch the Jack of Hearts in front and rear. Before he left the booth Curly had compared the writing of Mrs. Wylie with that on the sheet that had come by special delivery. The loop of the J's, the shape of the K's, the formation of the capital H in both cases were alike. So too was the general lack of character common to both, the peculiar hesitating drag of the letters.

Beyond question the same person had written both.

Certainly Mrs. Wylie was not warning the sheriff against herself. Then against whom? He must know her antecedents, and at once. There was no time for him to mole them out himself. Calling up a local detective agency, he asked the manager to let him know within an hour or two all that could be found out about the woman without alarming her.

"Wait a moment I think we have her on file. Hold the 'phone." The detective presently returned. "Yes. We can give you the facts. Will you come to the office for them?"

Fifteen minutes later Curly knew that Mrs. Wylie was the divorced wife of Lute Blackwell. She had come to Saguache from the mountains several years before. Soon after there had been an inconspicuous notice in the _Sentinel_ to the effect that Cora Blackwell was suing for divorce from Lute Blackwell, then a prisoner in the penitentiary at Yuma. Another news item followed a week later stating that the divorce had been granted together with the right to use her maiden name. Un.o.btrusively she had started her little store. Her former husband, paroled from the penitentiary a few months before the rustling episode, had at intervals made of her shop a loafing place since that time.

Curly returned to the Del Mar and sent his name up to Miss Cullison. With Kate and Bob there was also in the room Alec Flandrau.

The girl came forward lightly to meet him with the lance-straight poise that always seemed to him to express a brave spirit ardent and unafraid.

"Have you heard something?" she asked quickly.

"Yes. Tell me, when did your father last meet Lute Blackwell so far as you know?"

"I don't know. Not for years, I think. Why?"

The owner of the Map of Texas answered the question of his nephew. "He met him the other day. Let's see. It was right after the big poker game. We met him downstairs here. Luck had to straighten out some notions he had got."

"How?"

Flandrau, Senior, told the story of what had occurred in the hotel lobby.

"And you say he swore to get even?"

"That's what he said. And he looked like he meant it too."

"What is it? What have you found out?" Kate implored.

The young man told about the letters and Mrs. Wylie.

"We've got to get a move on us," he concluded. "For if Lute Blackwell did this thing to your father it's mighty serious for him."

Kate was white to the lips, but in no danger of breaking down. "Yes, if this man is in it he would not stop at less than murder. But I don't believe it. I know Father is alive. Ca.s.s Fendrick is the man we want. I'm sure of it."

Curly had before seen women hard as nails, gaunt strong mountaineers as tough as hickory withes. But he had never before seen that quality dwelling in a slim girlish figure of long soft curves, never seen it in a face of dewy freshness that could melt to the tenderest pity. She was like flint, and yet she could give herself with a pa.s.sionate tenderness to those she loved. He had seen animals guard their young with that same alert eager abandon. His conviction was that she would gladly die for her father if it were necessary. As he looked at her with hard unchanging eyes, his blood quickened to a fierce joy in her it had known for no other woman.

"First thing is to search the Jack of Hearts and see what's there. Are you with me, Uncle Alec?"

"I sure am, Curly;" and he reached for his hat.

Bob too was on his feet. "I'm going. You needn't any of you say I ain't, for I am."

Curly nodded. "If you'll do as you're told, Bob."

"I will. Cross my heart."

"May I come too?" Kate pleaded.

She was a strongwilled impulsive young woman, and her deference to Curly flattered him; but he shook his head none the less.

"No. You may wait in the parlor downstairs and I'll send Bob to you with any news. There's just a chance this may be a man's job and we want to go to it unhampered." He turned at the door with his warm smile. "By the way, I've got some news I forgot. I know where your father got the money to pay his poker debts. Mr. Jordan of the Cattlemen's National made him a personal loan. He figured it would not hurt the bank because the three men Luck paid it to would deposit it with the bank again."

"By George, that's what we did, too, every last one of us," his uncle admitted.

"Every little helps," Kate said; and her little double nod thanked Curly.

The young man stopped a moment after the others had gone. "I'm not going to let Bob get into danger," he promised.

"I knew you wouldn't," was her confident answer.

At the corner of the plaza Curly gave Bob instructions.

"You stay here and keep an eye on everyone that pa.s.ses. Don't try to stop anybody. Just size them up."

"Ain't I to go with you? I got a gun."

"You're to do as I say. What kind of a soldier would you make if you can't obey orders? I'm running this. If you don't like it trot along home."

"Oh, I'll stay," agreed the crestfallen youth.

Maloney met them in front of the Jack of Hearts.

"d.i.c.k, you go with me inside. Uncle Alec, will you keep guard outside?"

"No, bub, I won't. I knew Luck before you were walking bowlegged," the old cattleman answered brusquely.

Curly grinned. "All right. Don't blame me if you get shot up."

Mrs. Wylie's startled eyes told tales when she saw the three men. Her face was ashen.

"I'm here to play trumps, Mrs. Wylie. What secret has the Jack of Hearts got hidden from us?" young Flandrau demanded, his hard eyes fastened to her timorous ones.

"I--I--I don't know what you mean."

"No use. We're here for business. d.i.c.k, you stay with her. Don't let her leave or shout a warning."

He pa.s.sed into the back room, which was a kind of combination living room, kitchen and bedroom. A door led from the rear into a back yard littered with empty packing cases, garbage cans and waste paper. After taking a look around the yard he locked the back door noiselessly. There was no other apparent exit from the kitchen-bedroom except the one by which he and his uncle had entered from the shop. But he knew the place must have a cellar, and his inspection of the yard had showed no entrance there. He drew back the Navajo rug that covered the floor and found one of the old-fashioned trap doors some cheap houses have. Into this was fitted an iron ring with which to lift it.
