That open (but often shut) private eye, Nero Wolfe ignores police assumptions when he links three unrelated deaths and, with his meager force against N.Y.'s finest, ties in extortion with the murders. Inspector Cramer is redder-faced; Archie Goodwin lands in a rough mix-up; Wolfe expounds on the science and art of detection and his grumbles and snooperies prove out. Calculating.
