Based upon Max Hardonniere's own experience as a covert operative during World War II, this is the story of a young man whose acquaintance with Prime Minister Winston Churchill would lead to him being recruited and trained as a spy who would fight his own war from behind enemy lines.

When Darren Dirkowitz's evil stepbrother (code name Waldo) gets hold of Darren's tippity-top-secret spy journal, he threatens to expose it to the entire Preston Middle School student body. Unless, that is, Darren starts doing his dirty work for him. Now Darren's got to use the oh-so-cloak-and-daggery skills he's honed in his secret alternate life as Dirk Daring, Secret Agent to spy on kids at school. Naturally, he also sets up a separate, sneaky surveillance program to unearth Waldo's own secrets. As more and more ugly truths are exposed, new alliances are forged and old friendships broken. Can Darren learn to be true to himself and build real friendships for the first time in his life? Or will he retreat back into his exciting but imaginary shadow world?
