"Witty, fast moving, with a tight plot, believable characters, and unexpected ending, Killer Code is a delightful first novel that will leave you with a smile." – T. Mike Walker, author, The Butterfly Bride, Respect, and Voices of the Bottom of the World
"Compelling reading and Mr. Walker brilliantly evokes the culture of Silicon Valley and the varied and occasionally bizarre character of the people inhabiting it." – John Dizikes author of Opera in America, Winner of the 1993 National Book Critics Circle Award in Criticism
"In his new book, Killer Code, author John Walker combines both murder and comedy into a fast-paced mix of money and power that just may be the first mystery thriller set in the high-rolling environs of Silicon Valley. The novel accurately portrays the tremendous pressures of the software development world, and Walker throws in some good old-fashioned mystery and suspense to cook up a most satisfying read." – Ellen Tanner Marsh, New York Times Best Selling Author
