n, "and I simply
refuse to have anything more to do with you. You're being simply
disgusting. Need I say more?" added Bones.

The girl wrote: "Dear Sir,--No useful purpose would be served either in
replying to your letter of to-day's date, or re-opening the discussion
on the circumstances of which you complain."

Bones went back to his office feeling better. Hamilton left early that
afternoon, so that when, just after the girl had said "Good night," and
Bones himself was yawning over an evening paper, and there came a rap
at the door of the outer office, he was quite alone.

"Come in!" he yelled, and a young man, dressed in deep mourning,
eventually appeared through the door sacred to the use of Miss
Marguerite Whitland.

"I'm afraid I've come rather late in the day."

"I'm afraid you have, dear old thing," said Bones. "Come and sit down,
black one. Deepest sympathy and all that sort of thing."

The young man licked his lips. His age was about twenty-four, and he
had the appearance of being a semi-invalid, as, indeed, he was.

"It's rather late to see you on this matter," he said, "but your name
was only suggested to me about an hour ago."

It was the young man's turn to nod.

"That's right, sir," he said. "John Siker was my father. I'm his only
son."

Bones waited.

"I've heard it said, Mr. Tibbetts," said the young man--"at least, it
has been represented to me--that you are on the look-out for likely
businesses that show a profit."

"That's right," agreed Bones; "that show me a big profit," he added.

"Well, Siker's Detective Agency has made two thousand a year clear for
twenty years," said the young man. "We've got one of the best lists of
clients in the kingdom, and almost every big business man in the City
is on our list. With a little more attention than my father has been
able to give to it for the last two years, there's a fortune in it."

Bones was sitting upright now, his ey
