Slowly the time dragged by, until they heard a shouting in the distance, followed by a pistol shot. Then two horses burst into view, one ridden by Ostrello, and the other by a doctor who lived not a great distance away.

"I will do all I can," said the physician, as he leaped to the ground.

He set to work at once, meanwhile questioning the old woman regarding what had already been done. "That was all right--it has helped to put the patient into a perspiration and keep up the heart action."

"Another doctor is also coming," said Ostrello to Raymond and the detective.

"In that case I'll join my men," came from Adam Adams. "By that pistol shot something must be doing. I will be back later. See that that old woman does not get away." And he was off.

Something was indeed doing. The old mill had been surrounded and the chief of police had entered the building, followed by several other men of the party. The counterfeiters were taken by surprise, but they did not give up at once. Some began to fight, and in the melee two were seriously wounded. Then all but three surrendered, these three doing what they could to get out by a back way. One of the three was Matlock Styles.

The three men came out in the woods, and one was quickly shot in the leg, and fell headlong among the trees. Seeing this the second man shouted that he would surrender, and threw up his arms as a signal.

"You bloomin' fool! I'll not surrender!" cried Matlock Styles, and ran on, through the woods, and up the hill that led to the cottage.

He was still some distance off, when Adam Adams saw him coming. The detective had his pistol in his hand.

"Stop, Styles, or I'll fire on you!" he called out.

For an answer the Englishman raised his own pistol and fired point blank, the bullet cutting through the loose flap of Adam Adams' coat.

Then the Englishman went down, with a bullet in his left side. When Adam Adams ran up to him he was twisting and breathing heavily.

"You've done me up, hang you!" he gasped. "Oh, if I only could get at you!" and he tried to crawl towards his pistol, but Adam Adams promptly kicked it out of the way.

"You're down and out, Styles," said the detective. "It won't do you any good to squirm. You're in the hands of the law."

"What for, counterfeiting?"

"That and worse."

"Worse?"

"Yes, a good deal worse. Murder!"

By nightfall all of the prisoners were either in the jail or at the hospital at Sidham. Some of the secret service authorities from New York had arrived, and to them Adam Adams turned over the case, so far as it related to the counterfeiters.

"I did not start out to round up such a gang," he said, in speaking of the affair to Mr. Breslow, some days later. "I came here to clear up the murder mystery."

"But you get the credit, Adams," said the head of the secret service detail. "And you deserve it. But do you think you are going to convict Matlock Styles of the tragedy?"

"It's a sure thing. The _alibi_ won't bother me, for I can now prove it was a bogus one. John Watkins got the poison for him, and promised to impersonate him at Stony Hill, while the crime was being committed.

He did it, but I have found two people who thought it was not Styles after all. Watkins himself is willing to testify that he did the impersonating."

"How did they happen to use that strange powder?"

"Watkins got it from a friend of his, who afterwards mentioned the fact to Tom Ostrello. When Styles got it I suppose he thought the use of it might throw suspicion on Ostrello, which it did. Then suspicion was also thrown on Miss Langmore, so that the general public might get tangled up."

"Did Styles write that note, which was supposed to have been written by Mr. Langmore, saying she must obey or leave the house?"

"Yes. He is an expert penman, and most likely a regular forger as well as counterfeiter. He only made a mistake when he drank too much."

"Did Watkins know any of the details of the murder?"

"Yes. After it was over, Styles came to him and told his story, being half drunk at the time. He said he left home and came through the woods, where he saw Tom Ostrello just coming from the Langmore mansion.

As soon as the coast seemed clear, he ran past the bushes and got in the house by a window. He found Mr. Langmore in the library and asked again for the counterfeits. Langmore said he was going to give them to the authorities, and expose Styles. Then the Englishman said he would explain, and Langmore sat down in his chair to listen. Styles turned around, took some cotton from his pocket, and saturated it with the powder, and sprang at Langmore from behind. The victim struggled and got his face scratched from the Englishman's ring. Langmore was no match for his a.s.sailant, and in a minute the murder was done. Then Styles ran upstairs. He knew the servant was in the barn, and he heard Miss Langmore playing on the piano in the parlor. He met Mrs. Langmore just coming from her room. She was scared, but before she could scream or resist, he gave her what was left of the powder and she fell over where she was found. Then he stepped out of an upper window to the top of the piazza and dropped to the ground, and came away across the brook and through the woods."

"Then you are bound to convict him. What of Watkins?"

"I'll use him as a witness against Styles in the murder trial and then you can have him tried as a counterfeiter. The old woman will also prove a good witness. She is so old, and has promised to reform, so there is no use of our pushing a charge against her. The rest of the crowd will all get what they deserve. I'm glad we got the bogus printing plates."

"Have you heard anything of the Langmore estate?"

"Yes. Mr. Langmore left his wife her legal share, and the balance to his daughters, Margaret getting a little the larger portion. Mrs.

Langmore leaves her money to her sons, one-fourth to d.i.c.k, the spendthrift, and three-fourths to Tom. I have also rooted out some papers among Styles' effects, which will give Tom Ostrello his patent back, and also give some patent rights to Mr. Langmore's estate. I can tell you, Matlock Styles was a deep one. It was only once in a great while that he drank and bungled."

"Well, the greatest of criminals have their weak spots, you know that as well as I do. Styles, I suppose, also got up that bogus confession, signed in Miss Langmore's name."

"He did. When he found the girl wouldn't marry him, he was wild and ready for any treachery."

"And how is the girl doing?"

"I am going to see now."

When out on the street, Adam Adams ran into Tom Ostrello, arm in arm with Letty. He was amazed for an instant, and then his face broke into a smile.

"I just couldn't help it, Uncle Adam!" cried the girl. "I had to come here to congratulate Tom on his escape."

"Well, I don't blame you, Letty. Yes, it has turned out well for you.

I hope it turns out as well for Miss Langmore and Mr. Case."

Margaret was again at Martha Sampson's cottage. When the detective entered he heard a murmur of voices in one of the upper rooms. He ran upstairs, to find the girl sitting up in bed and Raymond by her side.

The young man's face was filled with happiness.

"Come in! Come in!" he cried joyously. "She has come around all right, Mr. Adams. She is a little weak still, but the doctor says she will be well as ever in a week or ten days. The good news has braced her up wonderfully."

"And all due to you, Mr. Adams," said the girl. "Oh, how can I ever thank you enough?" She clasped his hand warmly. "You are so good!"

"This is certainly famous," he replied, sitting down at the foot of the bed. "It's the best news yet. I have just left one happy couple and here I find another."

"You mean Tom Ostrello and that young lady from your office?" asked Raymond. And then, as the detective nodded, he went on: "I met them, and I asked them to come here. Margaret wanted to see them."

"I wish Tom to know that I want to be friends, always," said Margaret.

"We have had enough of trouble in the family. And when he gets married, I want to be friends with his wife, too."

"I am glad to hear that, for I know it will please Letty and she is a good girl. It may be-- Here they come, now!"

A minute later the newcomers were ushered into the sick room, and the two girls, who had never met, were introduced to each other. It was a happy meeting all around, and the lovers were all as devoted as lovers can well be. Seeing this, Adam Adams thought it about time to leave.

"I am going now," he said, and stopped at the door.
