This is a real case, not a puzzle out of a story magazine. I'm a detective, not a super-sleuth. Sherlock Holmes would know all about this case in no time, what with a magnifying glass and his knowledge of the bone structure of Polynesian aborigines. Philo Vance would solve it between puffs of a Regie cigarette, from simple deductions based on the squawks of those penguins we met up with yesterday. But not me. I don't know any more than you do. Maybe less, only I know how to act wise. I'm just blundering ahead, trying not to miss any of the more apparent lines of approach. Sooner or later the murderer will leave something open, and I'll stumble in.
