"You think it's a bomb plot?" asked Jane.

"I don't know what it is. These empire-mad fools stop at nothing.

Nothing is sacred to them, women, children, property. With fanatical energy and ability they commit murders, resort to arson, use poisons, foment strikes, wreck buildings, blow up ships, do anything, attempt anything to serve the Kaiser. Karl Boy-ed spent three millions here in America in two months, and Von Papen a million more. What for? Ten thousand dollars to one man to start a bomb factory, twenty-five thousand dollars to another to blow up a tunnel. Millions on millions for German propaganda was raised right here, and it is far from all spent yet. We've got to find out what the wonder-worker is and destroy it before it destroys--God knows what."

"Very well," said Jane with quiet determination, "I'll search their apartment."

"No, not that," said the chief, "I'll send some fake inspectors to test the electric wiring, and they'll do the searching. I do not know for sure that the Hoffs suspect you of watching them, but I'm taking no chances. It will be just as well for you and Dean to be out of the way to-morrow all day, so that you will have an alibi. Germany's secret agents are suspicious of everybody. They do not even trust their own people. What I want you and Dean to do is to try to follow the Hoffs and see where they go. I don't want to use the same persons twice to trail them as they may get suspicious."

"I can easily do that," said Jane, feeling relieved. "I'll tell Mother I want our car for all day."

"No, don't use your own car. They might recognize it. I'll provide another one. They gave two of my men the slip last week somewhere the other side of Tarrytown. Let's hope they are not so successful this time."

"But won't they recognize me?"

"Not if you disguise yourself with goggles and a dust coat. Dean can make up, too. He had practice enough at college, eh, Dean?"

Jane turned to look interestedly at Dean, who had the grace to color up.


She was right then. He was a college man, working in the secret service not for the sake of the job but for the sake of his country.

"Of course I can disguise myself too," she said enthusiastically, a new zest in her work asserting itself, now that she knew her principal co-operator was probably in the same social stratum as herself.

"You can rely on us, Chief," said Dean, as they left the office together. "We'll run them down."
