Compulsion
Sam didn’t come to San Francisco for its spectacular scenery, its hills, its cable cars or any of the countless attractions that made the city unique. He didn’t even want to come, had fought the urge for years.

It was a treacherous bay, Sam knew, with undertows and currents that could overwhelm the strongest swimmer.
