i--Miss White?"

"Good night," said the girl and closed the door in his face.

He cursed angrily in the dark and raised his hand to rap on the panel of
the door, but thought better of it and, turning, walked back to the
interested Crewe, who stood in the shadow of a lamp-post watching the
scene.

"Well?" asked Crewe.

"Confound the girl, she won't talk," grumbled Silva. "I'd give something
to break that pride of hers, Crewe. By jove, I'll do it one of these
days," he added between his teeth.

Crewe laughed.

"There's no sense in going off the deep end because a girl turns you
down," he said. "What did she say about the flat? And what did she say
about her visit to Albemarle Place?"

"She said nothing," said the other shortly. "Come along, let's go back
to the colonel."

On the return journey he declined to be drawn into any kind of

and who knew what our business was. That somebody was this infernal Jack
o' Judgment, but who is Jack o' Judgment, hey?"

He looked round fiercely.

"I'll tell you who he is," he went on, speaking slowly "He's somebody
who knows our gang as well as we know it ourselves, somebody who has
been on the inside, somebody who has access, or who has had access, to
our working methods. In fact," he said using his pet phrase, "a business
associate."

"Rubbish!" said Pinto.

This polished man of Portugal, who had come into the gang very late in
the day, was one of the few people who were privileged to offer blunt
opposition to the leader of the Boundary Gang.

"You might as well say it is I, or that it is Crewe, or Dempsey, or
Selby----"

"Or White," said the colonel slowl
