penetrating curiosity that she saw in Marion's eyes caused her to
blush with confusion. Unable to meet her friend's gaze steadily, she
shifted her eyes toward the most uninteresting part of the car, the
floor, and said:

"That looks like a dangerous letter. It ought to be turned over to the
police as soon as possible."

"Both of them, don't you think?" Marion inquired.

"Why? I don't see anything in this shorter one. My guess would be that
it was written by your cousin or one of his friends."

"But do you notice the way they both end?--the same words," Marion
insisted.

"Yes, I noticed that," Helen replied slowly. But that is such a
common, ordinary expression, almost like 'a,' 'an,' or 'the,' that it
doesn't mean much to me here. Where are the letters postmarked?"

"Both in Westmoreland."

"That's something in favor of your suspicion that both letters were
written by the same person," Helen admitted. "Still it doesn't
convince me. You wouldn't expect the Spring Lake boys to mail a letter
like the shorter one at Spring Lake, would you? That would stamp its
identity right away."

"You are sure those letters were written by different persons?" Marion
inquired curiously.
