In this third installment of the series, 11-year-old whiz-kids Nick
and Tesla discover that someone in the quiet town of Half Moon Bay
has placed their beloved Uncle Newt under electronic
surveillance-but who is spying on him, and why? To expose the
secret agent, Nick and Tesla build all kinds of outrageous
contraptions. Throughout the book, the narrative is interrupted by
blueprints and instructions so that budding young inventors can
follow along. Science and electronics have never been so much fun!
