should have reported him as a suspect,” stated Captain Mary Lewis sharply. Nancy flushed, and asked, “To whom should I have reported him? They would only have laughed at me. Nobody on that train knew who I was.” “Never take a chance when it comes to anything like that,” said Major Reed. “Where large numbers of lives are involved it’s excusable to be suspicious of your own brother, rather than take any chances.” Nancy didn’t flare up in anger or burst into tears, but looked the major squarely in the eyes. “I’m sure you’re right.

The description you’ve given is elaborate compared with some we get. We’ve sometimes caught ’em on little more than a shoestring.” He saluted respectfully and their car
