 What is Puerto Pacifico?
The series of events leading up to Pembroke's present occupation had commenced on a dismal, overcast evening in the South Pacific a year earlier. Bound for Sydney, two days out of Valparaiso, the Colombian tramp steamer Elena Mia had encountered a dense greenish fog which seemed vaguely redolent of citrus trees. Standing on the forward deck, Pembroke was one of the first to perceive the peculiar odor and to spot the immense gray hulk wallowing in the murky distance. Pembroke came as close to being a professional adventurer as one can in these days of regimented travel, organized peril, and political restriction. Loyalty to person or to people was a trait Pembroke had never recognized in himself, nor had it ever been expected of him. His situation could have been any small western American seacoast city. One in particular, an attractive woman of about thirty, tossed back her long, chestnut locks and gazed up intently at Pembroke as he passed. "You're not casual enough, for one thing," said Pembroke, deciding to play along with her for the moment. "Incidentally, just where are we, anyway? "Puerto Pacifico," she told him. It means peaceful port. But as he left the shop he began checking off every west coast state, city, town, and inlet. None, to the best of his knowledge, was called Puerto Pacifico. "Which way is it to San Francisco?" asked Pembroke. "This is Puerto Pacifico." "All cargo ships, I'll bet. No passengers," said Pembroke.
