moment Karlov puts his hands on you
the whole game goes blooey. That's the plain fact. There is death in
this game. These madmen expect to blow up the United States on May
first. We are easing them along because we want the top men in our net.
But if Karlov takes it into his head to get you, and succeeds, he'll
have a stranglehold on the whole local service; because we'd have to
make great concessions to free you."

"Why wasn't I told this at the start?"

"You were told, indirectly. We did not care to frighten you."

"I'm not frightened," said Kitty.

"Nope. But we wish to the Lord you were, Miss Conover. When you want to
come home, wire me and I'll motor out for you."

Another fragment. Karlov's agent sought his chief and found him in the
cellar of the old house, sinisterly engaged. The wall bench was littered
with paraphernalia well known to certain chemists. Had the New York bomb
squad known of the existence of this den, the short hair on their necks
would have risen.

"Well?" greeted Karlov, moodily.

building for his home. No elevator goes up unless you have credentials.
Our man is hiding there, Boris."

Karlov dry-washed his hands. "We'll send him one of the samples if we

"Every day but Sunday."

"Good news. Two bolts; one or the other will go home."

About the same time in Cutty's apartment rather an amusing comedy took
place. Professor Ryan, late physical instructor at one of the aviation
camps, stood Hawksley in front of him and ran his hard hands over the
young man's body. Miss Frances stood at one side, her arms folded, her
expression skeptical.

"Nothin' the matter with you, Bo, but the crack on the conk."

"Right-o!" agreed Hawksley.

"Lemme see your hands. Humph. Soft. Now stand on that threshold. That's
it. Walk t' the' end o' the hall an' back. Step lively."

"But," began Miss Frances in protest. This was cruelty.

"I'm the doctor, miss," interrupted Ryan, crisply. "If he falls down he
goes t' bed, an' you stay. If he makes it, he follows my instructions."

When Hawksley returned to the starting line the walls rocked, there were
two or three blinding stabs of pain; but he faced this
