“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 can’t talk about.”
“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.”
