He hung up the receiver, turned thoughtfully, opened the door again, and walked into the sunlit living room.
"Look here!" cried the Captain in a high state of excitement. "I've got a lot of numbers out of it already."
"Wonderful!" murmured the Tracer, looking over the young man's broad shoulders at a sheet of paper bearing these numbers:
9—14—5—22—5—18—19—1—23—25—15—21—2—21—20—15—14—3—5—9—12—15—22—5—25—15—21—5—4—9—20—8—9—14—23—15—15—4.
"Marvelous!" repeated the Tracer, smiling. "Now what do you suppose those numbers can stand for?"
"Letters!" announced the Captain triumphantly. "Take the number nine, for example. The ninth letter in the alphabet is I! Mr. Keen, suppose we try writing down the letters according to that system!"
"Suppose we do," agreed the Tracer gravely.
So, counting under his breath, the young man set down the letters in the following order, not attempting to group them into words:
INEVERSAWYOUBUTONCEILOVEYOUEDITHINWOOD.
Then he leaned back, excited, triumphant.
