eleven dollars and
sixty-three cents, and the marked bill was nearly half of the sum. He
begged them to let him go--offered them his watch, his ring, his
scarf-pin--but the justice insisted on cash. Then he told them that the
bill had a formula on it that was valuable to him and no one else.

"The justice was obdurate, and Mr. Poritol finally hit on the device
which you have seen. It fitted in well with his sense of the theatrical;
and the detective says that there was not a scrap of paper at hand. The
point was that Mr. Poritol was more afraid of delay than anything else.
He knew that I would put someone on his track."

"When did all this happen?" asked Orme.

"Yesterday afternoon. Mr. Poritol came back to Chicago by trolley and got
some money. He went back to the country justice and discovered that the
marked bill had been paid out. He has followed it through several persons
to you, just as Maku did, and as I have done. But I heard nothing of the
Japanese."

"You shouldn't have attempted this alone," said Orme, solicitously.

She smiled faintly. "I dared not let anyone into the secret. I was afraid
that a detective might learn too much." She sighed wearily. "I have been
on the trail since morning."

"And how did you finally get my address?"

"The man who paid the bill in at the hat-shop lives in Hyde Park. I did
not get to him until this evening, while he was at dinner. He directed me
to the hat-shop, which, of course, was closed. I found the address of the
owner of the shop in the directory and went to his house. He remembered
the bill, and gave me the addresses of his two clerks. The second clerk I
saw proved to be the one who had paid the bill to you. Luckily he
remembered your address."

Orme stirred himself. "Then the Japanese have the directions for finding
the papers."

"My predicament," said the girl, "is complicated by the question whether
the bill does actually carry definite directions."

"It carries something--a set of abbreviations," said Orme. "But I could
not make them out. Let us hope that the Japanese can't. The best course
for us to take is to go at once to see Walsh, the burglar."

He assumed that she would accept his aid.

"That is good of you," she said. "But it seems a little hopeless, doesn't
it?"

"Why? What else can we do? I suppose you saw to it that no one else
should have access to Walsh."

"Yes, father arranged that by telephone. The man is in solitary
confinement. Sever
