"That's right," Scotty said. He held up a heavy volume called Cryptography for the Student. It was the only book on the subject in the scientist's library. "We've been going through this, trying to find some kind of clue. Honest, it's impossible."
"There are so many codes and ciphers," Barby added. "Dozens. And it says some of them can only be broken by days of work, by experts."
"There's not an expert in the house, either," Rick concluded. "I didn't think, when Bill called us up about it, that Chahda would use a code we couldn't figure out, but I didn't expect a page like that."
Hartson Brant read through the cable again. "How do you know you can't figure it out? Perhaps a little reasoning will clear the air. Chahda must have put a key in the message somewhere. How about this 'L' in front of his name?"
"That's right," Barby said excitedly. "That must mean something, because his name is Chahda Sundararaman. There isn't an L in it anywhere."
The scientist handed the cable back to Rick. "I'm about as curious as I can get," he said, "but I refuse to think any more about it until you hand me the clear version. I agree that Chahda wouldn't send a code you couldn't solve, so my advice is put the code book away. You won't need it, I'm sure. This isn't any code you'll find in there."
He started out of the room, then paused at the door, his eyes twinkling. "Will you have dinner at the table with us, or shall I ask mother to break out some emergency rations so you can stay on the job?"
"We'll eat with the family," Scotty replied. "We can keep on thinking while we eat, can't we?"
Rick watched his father wink at Barby, then walk toward the kitchen. "Dad's right," he announced. "He must be. So let's put the book back and start figuring this out. The answer probably is easy as pie once we find the key."
"How about starting with that odd letter?" Scotty asked. "That has to mean something."
