t the Hoffs talked about. That would help a
lot. If ever he was caught prowling about the hall, the fact that he was
your chauffeur would provide him with an alibi. Do you think you can fix
it up with your father?"

"I'm sure of it. When can he come?"

"The sooner the better--to-night--to-morrow."

"I'll tell Dad at dinner to-night that I've learned of a good chauffeur
and have asked him to come in at eight this evening."

"Fine," said Carter. "He'll be there. And don't forget to report once a
day to the Chief."

"I won't."

"And if anything unexpected turns up," said Carter, "and you need help,
take a good look at that nurse that is passing."

Jane turned curiously to inspect a buxom girl in a drab nurse's costume
who was wheeling a baby carriage along the sidewalk near-by. Seeing
herself observed the girl stopped, and at a sign from Carter wheeled her
charge up to where they were standing.

"K-22," said Carter, "I want to introduce you to K-19."

Gravely the two girls, nodding, inspected each other.

"She always wears a blue bow at her neck," Carter added, "so you can
recognize her by that."

The girl smilingly nodded again and wheeled the carriage on up the
Drive.

"Who is she?" Jane asked eagerly, turning to Carter.

"Just K-22," said the agent, "and all she knows about you is that you
are K-19. That's the way we work in the service mostly. The less one
operative knows about another the better, for what you don't know you

"Doesn't she even know my name?" persisted Jane.

"She may have found it out for herself while she has been watching the
Hoffs, but we didn't tell her. Nobody in the service knows who you are
except the Chief and myself--and of course K-27 will have to know if he
takes the chauffeur's job."

"What is his name?"

"I don't know yet," said Carter gravely. "I haven't seen his references,
so I don't know what name they are made out in. You can find out what to
call him when he reports to-night. You'll see that he gets the job?"

"Indeed I will," answered Jane, experiencing a sense of relief at the
prospect of having some one at hand in the household with whom she could
discuss her activities.

And as she had anticipated she had little difficulty in interesting her
father in the subject of a new chauffeur. Mr. Strong for several days
had been trying to find one without success.

"You say this man's last place was with the British High Commission."

"Some on
