August Riordan, a cynical jazz bass-playing San Francisco private eye, is hired by Silicon Valley multi-millionaire Edwin Bishop, an entrepreneur who has founded several highly successful software game companies.

Riordanís search for the thief takes him through both the high-tech Silicon Valley and the underground S&M scene in San Francisco.
