"Norty's foreign letters, or some of them at any rate."

"Chris! You never went into her room and took them?"

"That's exactly what I did, old sport! I'm going to look them over, and put them back before she finds out."

Marjorie gasped.

"But look here! It doesn't seem quite—straight, somehow."

"Can't be helped in the circumstances," replied Chrissie laconically. "We've got to outwit her somehow. It's a case of 'Greek meets Greek'. How else are we to find out anything?"

"I don't know."

The idea of entering a teacher's bedroom and taking and reading her private correspondence was intensely repugnant to Marjorie. Her face betrayed her feeling.

"You'd never do on secret service," said Chrissie, shaking her head. "I thought you were patriotic enough to dare anything for the sake of your country. Go downstairs if you don't want to see these letters. I'll read them by myself."

"I wish you'd put them back at once," urged Marjorie.
