“You know quite well what,” Wolfe declared. “The eraser was yanked out and placed purposely, and was a part of the message. No doubt as a dot after the N to show it was an initial? And he was interrupted permanently before he could put one after the W?”

“Sarcasm don’t change it any. It’s still NW.”

“No. It isn’t. It never was.”

“For me and the district attorney it is. I guess we’d better get on down to his office.”

Wolfe upturned a palm. “There you are. You’re not hare-brained, but you are pigheaded. I warn you, sir, that if you proceed on the assumption that Mr. Heller’s message says NW, you are doomed; the best you can expect is to be tagged a jackass.”

“I suppose you know what it does say.”

“Yes.”

“You do?”

“Yes.”

“I’m waiting.”
