man of your
experience--"

"I am not afraid to tackle it if I can see the formula," Garth answered
quietly.

"Say, Simmons," George put in with a wry face, "if there's anything
phony about your education, drop off here."

Garth fingered a frayed sheet of white paper.

"I am not afraid if I can see the formula," he repeated.

The leader turned to Nora.

"You're sure there's some of the stuff in the safe with the formula? The
foreigner wouldn't dicker without a sample to analyze."

"I saw the formula and the sacks put in the safe to-night," she
answered.

George shook his head.

"Nora, you're a wonder."

"No wonder," she said contemptuously. "Nothing but hard work. An
imbecile could have made friends with the housekeeper, but it took
drudgery to get at the old man. I won't waste that. If there's any
slip--"

The leader glanced at the gray mask.

"That's up to Simmons now," he said.

CHAPTER III

IN THE STEEL ROOM

Garth's fingers played with the piece of white paper.

"You haven't told me where the house is," he said.

The moment the leader had answered Garth was standing on the bench. He
waved his arm. Suddenly he blew out the lamp.

"On the dock!" he stammered to the darkness. "A noise!"

As the others crept to the door he scratched rapidly and silently with a

"If your nerves jump like that, Simmons, what a chance we'll have!"
George said. "Not a sign. Light up."

Garth struck the match and relighted the lamp.

"I never take unnecessary risks," he said simply.

Nora, he knew, would guess that his excess of caution was a police
trick. His eyes sought her anxiously as the lamp flamed, but she gave no
sign. After a moment she whispered:

"Let's start. It--it frightens me here."

The leader opened the door.

"It's time," he said. "They're asleep in the house by now."

They followed him, threading obscure spaces and alleyways to the
unlighted end of a street which deployed into a stone mason's yard, and
always Garth asked:

"Will she whisper my life away to the others?"

A taxicab waited there. Garth manoeuvred so that he had a seat by the
window. He let his hand, which clenched the piece of paper, dangle
through. Such policemen as he saw were indifferent until crossing One
Hundred and Twenty-fifth Street he noticed one wh
