"Because we haven't satisfied ourselves about what Mason and the black valet were doing on the river with that boatman. If we find that the old gray-bearded fellow was the one who brought the body to the morgue, it would seem to indicate that Mason and the c.o.o.n know something about how Mr. Dalton may have met his doom. Remember the object they had towing behind the boat may have been the old broker's corpse. We can find out by attending the coroner's inquest and gaining a glimpse of the man who picked up the body."

"Then we shall do so."

On the following day they went to the morgue again and there found the coroner and his jury.

The inquest was in progress.

As the boatman who found the body was the only witness present the Bradys saw him the moment they entered the building.

It proved that their suspicion was correct.

He was the same little old man whom they had seen rowing Mason and Johnson out on the river.

Satisfied of this and having learned his address, the detectives left the building with renewed hope in their hearts.

Outside, Harry said to his partner:

"It's the same fellow, sure enough."

"No doubt about it, Harry. But then, he may have found the body long before he met the negro and Mason. He may have learned whose corpse it was and telegraphed to Mason to come down to the river and identify it."

Harry shook his head.

"I don't agree with your view," said he.

"Why not? It's plausible."

"No, it ain't. It don't account for Johnson being there ahead of Mason."

"By Jove, I didn't think of that."

"I tell you, Old King Brady, the whole circ.u.mstance is so suspicious that I'm yet of the opinion that the whole thing is a deep-laid plot, and I'm convinced that we will get at the bottom of the mystery if we keep a watch on the foxy Mr. Mason."

"It won't do any harm to try a while longer."

Harry looked pleased to hear this, and they went downtown and put their plan in operation at once.

Within the next few days several important events occurred.

The body was taken from the morgue and was buried from Mr. Dalton's house, Lizzie and Mason being the chief mourners.

The Bradys had found out who Mr. Dalton's lawyer was.

Having called on him and explained their suspicions of Mason, they asked him if he had seen Mr. Dalton's will.

He told them that Mason had given it to him that morning, with a request that it be read at the house that afternoon.

It was then sealed up and according to Mason's story, had been in Mr.

Dalton's safe a long time, in the Broad street office.

"We must hear the contents of that will," said Old King Brady. "As Mason is an unscrupulous man, we fear he may have tampered with it."

"You might disguise yourselves and go with me," suggested the lawyer.

"I could tell Mason you were called on as witnesses."

"Very well. What time are you going there?"

"I'll leave here at four o'clock."

"We shall be on hand to go with you."

With this understanding they separated.

The Bradys went home and disguised themselves.

Both were expert at such work, and quickly made such a wonderful change in their outward appearance that they could safely defy recognition.

Harry was made up as a stylish young woman, and Old King Brady, in a black wig and beard, looked like a minister.

The lawyer did not know them when they returned to his office, and laughed heartily when he found out who they were.

"I never saw such skillful disguising done before," he exclaimed, admiringly, "and I can a.s.sure you that Mason will not know who you are."

They proceeded to Mr. Dalton's house and were introduced to Lizzie and the broker's nephew as two witnesses to the reading of the will.

Neither Mason nor the girl knew the detectives.

When all were seated and the lawyer had made a few remarks about his business, he opened the seals on the will and read it aloud.

By this paper the old broker left a fortune amounting to half a million, most of which was invested in stocks, bonds and mortgages.

But it was a peculiar will.

After speaking of the high regard in which he held Ronald Mason, the broker went on to say that he earnestly desired his daughter to marry the young man. If she did so she was to receive half the fortune. If she failed to do so, every cent was to go to Mason.

The brokerage business was left to him to do with it as he pleased.

When the lawyer ceased reading, Lizzie Dalton was as pale as death.

Rising to her feet she bitterly denounced the terms of the will, and said:

"I don't believe my father ever wrote such a will. He always was opposed to Mason marrying me. So was I. And what is more, if I forfeit every dollar coming to me, I'll never marry that man!"

She pointed at Mason.

His clean-shaven face was convulsed with anger.

"So!" he sneered. "That's your answer, is it?"
